calypso's Issues

Auto detecting Clang modules

Hello Elie,

After the 'Auto-detect Clang module map files and add module maps for libc and POSIX standard headers' push today, most of the examples in the libstdc++ directory don't work? Is there something missing from that push? Or should the command line be different now or something?

The errors are similar to this (some are missing ptrdiff_t also):
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/ext/new_allocator.h(61): Error: undefined identifier 'size_t'

Paradoxically the iterator example actually parsed, when it never worked before :)

I also saw the Qt5 demo and tried it here but it gives me a few errors like this:
Error: struct cpp..div_t conflicts with static import cpp..div_t at /usr/include/stdlib.h(97)
and then a template specialization error, just in case you aren't seeing the same thing.

Thanks,
Kelly

assert(handle !in _handleToDSO) in setDSOForHandle fails on OSX

@Syniurge @klickverbot @ MartinNowak (since this seem to touch on druntime shared library initialization issues)

to reproduce: same test case as in #63

$calypso_D/lib/libcalypso-ldc-shared.dylib is being registered twice; depending on program, it could be another file that is registered twice;
workaround: just return from _d_dso_registry (in Calypso/runtime/druntime/src/rt/sections_elf_shared.d) when input corresponds to a so already registered.

Here is where it would fail:

#in void setDSOForHandle(DSO* pdso, void* handle):
assert(handle !in _handleToDSO); // fails

not sure if the fix is good enough though, doesn't seem so based on other bug i have after that

cpp11-push has undefined references

Dlib matrix.h modmap error

Hello Elie,

I am getting an error when trying to modmap dlib/matrix/matrix.h, which is one the main headers needed for much of Dlib. It appears as though returning the 'literal_assign_helper' struct value at line 1670 of matrix.h is the problem. If you need more information on the bug, please let me know.

Here is part of the backtrace:

Libstdc++ array error (happens in other libs)

Hello Elie,

When trying to compile the array.h libstdc++ example we get this error:

/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/bits/exception_ptr.h(116): Error: class cpp.std.__exception_ptr.exception_ptr.exception_ptr identity assignment operator overload is illegal

and a few very similar errors (along with this same error) occur when trying to compile some other libs. I just thought I would document it here to make it somewhat of a priority.

Thanks,
Kelly

Can't build after clang submodule added

Hello Elie,

I still can't build Calypso even after the last couple changes to help with the new clang submodule. I rebuilt llvm in debug mode (which is going to really suck for build times and the QT demo), added libc++ and libc++-abi, since that seemed to be required??? Not absolutely sure on that one. Now I get this error:

[  0%] Built target impcnvgen
[  0%] Built target idgen
[ 16%] Built target LDCShared
[ 16%] Performing configure step for 'clang'
-- Found LLVM_CONFIG as /usr/local/bin/llvm-config
CMake Error at CMakeLists.txt:62 (if):
  if given arguments:

    "STREQUAL" "Debug" "AND" "NOT" "Debug+Asserts" "STREQUAL" "Debug"

  Unknown arguments specified

-- Configuring incomplete, errors occurred!

Maybe my version of cmake isn't new enough? cmake-2.8.12.2? I checked into this a little (after a bunch of errors with llvm stuff) and couldn't see what was wrong.

'Frustrated' would be the word for my state of mind at this point, because I would like to try out the new Ogre demo and the build process really needs to be easier than this. I think the install instructions on the website need updating ...and with absolutely dead easy cut-n-paste instructions or people are going to get frustrated and not try Calypso out.

Sorry to be a nag, but it takes a good 30 mins to rebuild llvm/libc++, etc. and I have tried at least 4-5 different combinations over the last couple days and still don't have a working Calypso binary :(

Thanks,
Kelly

P.S. Btw, I can't use the Ubuntu binaries you have spoken of for llvm/clang, because I prefer not to be on the absolute bleeding edge with my linux installs, so I am on 14.04 and not 15.04. I believe this would be the norm, as running non-LTS versions of Ubuntu is a little rare. I literally can't upgrade because the version of linux on my Calypso machine (which is non production) doesn't have an upgrade path to non-LTS versions.

duplicate symbol __D6ℂcpp3std9type_info9type_info6__initZ

on OSX, I'm getting:

when adding:

modmap (C++) "<vector>";
import (C++) std.vector;

is there an up to date document that contains C++ features support + limitations?

Eg, I'd like to know whether this could work with things like:

stdio.h
opencv2/opencv.hpp
<boost>

I'm sure others are wondering too

EDIT: summarizing from answers below

a proper test suite
finish MSVC support (catching exceptions)
dtor calls by the GC
copy ctor calls for function arguments => done recent commits
documentation
more testing with more libraries and platforms (esp. OS X).

ubuntu Build instructions

I could not find the build instructions anywhere. I figured it out how to do it by googling and making cmake happy. Here are the instructions that work for Ubuntu 16.04 in case someone else wants to try this awesome compiler:

Add the llvm-3.9 repo
sudo apt-get install llvm-3.9 clang-3.9 ninja-build systemtap-sdt-dev
Clone this repo and cd into it
git submodule update --init
mkdir build && cd build

make

Loss of qualifiers in function parameters in Clang template instantiations

Hello Elie,

It looks like the list.d example stopped working a couple weeks back.

/home/wilsonk/Downloads/Calypso/tests/calypso/libstdc++/list/list.d(76): Error: template cpp.std.list.list!(int, *allocator!int).list.remove_if cannot deduce function from argument types !()(bool function(const(int))), candidates are:

Just thought I would let you know in case you didn't see it. The qtdemo (along with my expanded version that I haven't pushed yet) and all other libstdc++ examples work the same after this weeks changes, though, so no regressions there.

Project highlighting and first public beta version

Hi! I think that it's very important to make first public release something like beta version, it will help to attract attention for more developers to project, and there is good chance that some of them will help of fixing and improving project.

What do you think about this idea?

Errors while running CTest

is `modmap (C++) "basics.cpp";` an error (instead of basics.h) ?

all the code in calypso shows modmap (C++) {foo.h or foo} except for:

tests/calypso/basics.d:14:1:modmap (C++) "basics.cpp";

is it an error to put the source file instead of header file? The docs don't specify which should be used; I'm guessing it's ok to add .h and .cpp; however, instructions in basics3.d shows:

* Build with:
 *   $ clang++ -std=c++11 -c basics.cpp -o basics.cpp.o
 *   $ ldc2 -cpp-args -std=c++11 basics.cpp.o -L-lstdc++ basics.d

will that introduce ODR violations since ldc2 command will get the obj both from basics.cpp.o and from .calypso_cache/*.o ?

GDAL error again

Hello Elie,

It looks like there was a regression for the GDAL example after the last few months since the last time I was around :)

I get this error:

ldc2 basics.cpp.o deletes source file basics.cpp

following instructions from https://github.com/Syniurge/Calypso#specific-flags-and-building-the-basic-example :

EDIT: basics.cpp doesn't get deleted if i instead write:

clang++ -std=c++11 -c basics.cpp -o basics2.cpp.o
path_to_build/ldc2 -cpp-args -std=c++11 basics2.cpp.o -L-lstdc++ basics.d

EDIT: IIRC same issue on ubuntu

Build Failure with Nix: fatal error: 'typeinfo' file not found

I am working on reproducible builds for LDC and you project as well using the Nix package manager.
I have ldc working fine however I am stuck on an issue with calypso's build when it tries to compile runtime/druntime/src/ldc/eh/cpp/unwind-cxx.h:33:10 which is from what I can tell included in line one of build/runtime/calypso_cache.h. For some reason it cannot handle the following line as it throws fatal error: 'typeinfo' file not found stopping the build:

#include <typeinfo>

You can test my build environment on any platform that Nix support (linux, osx, cygwin, etc.) by cloning my nix expressions for your project with instructions Nekroze/ldc-calypso.nix and you can find the output of my build (with the middle (boring) part removed) at this gist.

OS X build issue

I am just adding this in case someone else runs into this problem. I was building Calypso on OS X and I needed to add '-lc++abi' to the CMAKE_EXE_LINKER_FLAGS to get things compiled. There was an error like

Undefined symbols for architecture x86_64: 
    "std::terminate()", referenced from: 
        _main in test-648ddf.o

Just thought I should mention it.

GDAL example problems on OS X

GDAL almost works out-of-the-box on OS X but it needs a couple changes. Elie can you patch cpptypes.h with this please, as it is too much work for such a simple change to make a PR IMHO:

 }

Then the GDAL example will compile but not quite link because of this:

      __siginfo::operator=(__siginfo const&) in __cpp___siginfo.o

If you just remove __cpp___siginfo.o from the link line from the verbose Calypso output by hand, then the example compiles. I am not sure why the above error is appearing...I tried to include -lc++ and -lc++abi to no avail???

There seems to be one major error holding back a few nice VTK examples. I have isolated it so that I could add it to the basics.hpp example test code like so:

    template <class T>
    class testClassTemplate:
    public testClassTemplate<arrayOfTen<T>>
    {
    public:
      enum test {
        FREE,
        DELETE
      };

    protected:
      int test;

    };

Then instantiate from basics.d ala. "auto tt = new testClassTemplate!(arrayOfTen!int);" and you get this error:

basics.hpp(129): Error: variable cpp.test.testClassTemplate.testClassTemplate!(arrayOfTen!int).testClassTemplate.test conflicts with enum cpp.test.testClassTemplate.testClassTemplate!(arrayOfTen!int).testClassTemplate.test at basics.hpp(123)
basics.d(157): Error: template instance cpp.test.testClassTemplate.testClassTemplate!(arrayOfTen!int) error instantiating

I guess there is a problem with Type::merge() and decorations in mtype.c...maybe? Anyways, I just took a quick look and thought that was where the problem lay.

Thanks,
Kelly

Needing to define CLANG_INCLUDE_DIRS also...

Hello. Please see the following session transcript. The Calypso readme only tells to define LLVM_SOURCE_PATH on the CMake command line, and even the http://wiki.dlang.org/Building_LDC_from_source page does not mention anything about having to manually define CLANG_INCLUDE_DIRS but only if I include that then CMake runs correctly.

macro functions not mapped to D

macros don't seemed to be mapped to D, despite what's said in https://wiki.dlang.org/Calypso: Constant and empty preprocessor macros (mapped to enums).

Other tools support macros (eg: swig, dstep etc)

test.h:

#define my_macro 42
#define my_macro2(x) (2*x)

main.d:

modmap (C++) "test.h";
import (C++) _;
void main(){
  enum a1=my_macro;  // Error: undefined identifier 'my_macro'
  enum a2=my_macro2(3);  // Error: undefined identifier 'my_macro2'
}

Use cases:
many (eg: CV_32F in opencv etc)

workaround:
add this in test.h:

enum class macros{
	_CV_8U=CV_8U,
	_CV_32F=CV_32F,
};

and in main.d:

import (C++) macros;
enum CV_8U=macros._CV_8U;

obviously, not ideal.

And for macro function, the workaround is more involved (define a template etc), and generates other issues: #67

EDIT: and this is despite:
Dsymbol* DeclMapper::VisitMacro(const clang::IdentifierInfo* II, const clang::Expr* E)
in ddmd/cpp/cppmodule.cpp

Can't build today

Hello Elie,

I tried building today (Oct 14), after the change to the clang libs instead of the binary, but I get this error when trying to link ldc2 (everything else builds fine up until linking):

I updated clang/llvm to the latest 3.6 version. I can see that AnnotateHappensAfter is defined in libclang_rt.tsan-x86_64.a and I try to link this lib in manually, but I still get the same errors?? Not sure what the problem is. Any ideas?

Build with external clang

I am trying to build your awesome project with a pre-installed version of clang, still 3.6 but pre-built and on the lib and include paths but I am not having any success and I am rather new to cmake.

Is there a way to get cmake to do this or is there some switch that your project can read to use a different clang without having to build it?

Unless your project modifies clang but it doesn't seem to so this should be doable and I think a good feature to have, it would keep compile times down as well.

Several libs now fail with typedefs conflicting with themselves

Hello Elie,

I have managed to get several libs to compile somewhat but I keep running into errors like this:

/usr/include/_G_config.h(21): Error: struct cpp.core.stdc.zmq._G_fpos_t conflicts with static import cpp.core.stdc.zmq._G_fpos_t at /usr/include/_G_config.h(21)
/usr/include/_G_config.h(26): Error: struct cpp.core.stdc.zmq._G_fpos64_t conflicts with static import cpp.core.stdc.zmq._G_fpos64_t at /usr/include/_G_config.h(26)
/usr/include/libio.h(369): Error: struct cpp.core.stdc.zmq._IO_cookie_io_functions_t conflicts with static import cpp.core.stdc.zmq._IO_cookie_io_functions_t at /usr/include/libio.h(369)

Other types like pthread_t, etc. don't work and the libstdc++ example for has similar errors. It seems like this is an issue that needs to be addressed fairly quickly, but I don't know why it is happening.

There was an error like this in a scintilla header and I just replaced the typedef by hand everywhere in the file, and then every part of the library that I tested would compile (at least a dozen headers). Woohoo.

Thanks,
Kelly

a C++ derived class that defines an operator hides automatic base class conversion

@Syniurge : a C++ derived class that defines an operator hides automatic base class conversion

test.h:

struct A{ int x;};

struct B : public A{
  // comment to remove error
  operator float() const;
};

main.d:

modmap (C++) "test.h";
import (C++) A;
import (C++) B;

void main(){
  B b;
  int bx=b.x;
}

compiling produces this error:
Error: template instance opCast!(A) does not match template declaration opCast(type : float)

The error goes away if we remove operator float() const;

It works if we add operator A*() {return this;} in B and change the D code to:
int bx=(cast(A*)b).x; but this is obviously not practical.

Calypso could then exist as a LDC plugin in the form of a shared library.

It is designed so that when the day comes splitting Calypso from LDC will be easy and Calypso could then exist as a LDC plugin in the form of a shared library.

Is there already a roadmap with open issues for this day to happen?

FastFlow test case

Hello Elie,

There is an issue with trying to instantiate an abstract class from the FastFlow C++ library in a D test program. If I use this simple test program:

modmap (C++) "ff/farm.hpp";
import (C++) ff.ff_node;
class Worker : ff_node {
//alias svc = cpp.ff.ff_node.ff_node.svc;
public:
override void* svc(void * task) { return task; }
}
void main() {}

I get this error:

test.d(10): Error: function test.Worker.svc does not override any function, did you mean to override 'cpp.ff.ff_node.ff_node.svc'?

You can see I tried to use an alias to get the override to work (and I tried a few other things to no avail). I tried making a cpp file and overriding in a simple class and then using that class also, bit it didn't work either.

Thanks,
Kelly

Random memory corruption with GCC 4.9.2 (and failure to compile the Qt5 demo)

When compiled with (Ubuntu 15.04) GCC 4.9.2, LDC + Calypso fails to compile the Qt5 demo. It turned out that sometimes a vptr gets corrupted, sometimes it's the last bytes of a Type... and I haven't been able to pinpoint when the corruption happens, because using a breakpoint and querying the values through gdb would always prevent the corruption from happening or wreaking havoc and the compilation of the Qt5 demo would terminate successfully.

None of those random issues occurred with Calypso built with Clang 3.6:

    export CC=clang
    export CXX=clang++
    cmake (...)

The corruption seems related to the recently enabled instantiation of C++ templated constructors because it's always them which get corrupted. Any idea on how to track the issue down? For now I have given up and switched to Clang, and will add a note to the README if this doesn't get fixed.

Changes after C++11 fixes Sept 2016

Here is a diff of a few of the comments that can be removed/changed in the libstdc++ examples since the C++11 fixes (I will try to flesh out some better example code and finish array.d, etc. soon) :

Qt5 demo

Hello Elie,

Spectacular job on getting far enough to get a Qt demo to work. Unfortunately I can't quite get it to build here :(

I am also getting a couple new errors in the libstdc++ tests, and the pertinent one is when compiling the 'set' example. The reason this is pertinent is that I get the exact same error with the Qt5 demo, but the example is so simple with set.d that it might be easier to track down. When compiling set.d with "ldc2 -L-lstdc++ set.d" I get this error:

And I also see that 'trivial dtor' error above when compiling the Qt5 demo (right after Calypso tries to output the code for 'allocator').

So I am not sure if you were seeing this error for set.d or qt5demo.d or not, but I am seeing it here. I don't have any extra modulemap_d files anywhere or anything...everything is the same as a few days ago when set.d worked, so I don't know what is going on.

Have you run into this before? Any ideas on how to fix it?

Thanks,
Kelly

Qt 5 simple demo compiles but fails to start

Executing qt5demo_simple fails with:

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.

Reinstalling the application may fix this problem.

Need binary to test

Hi! I am Suliman, who asked about help with GDAL lib. Could you build new release new binaries for Windows. I would like to test GDAL again, you said that it's shout work now, but as you know I have only basic knolages in programming.

Maybe you could example of using GDAL to Calypso examples, to get more people to be able use GDAL with D?

Qt demo issue

Hey Elie,

I am building against Qt5.5.1 downloaded straight from the Qt website (ie. not compiled by me) and I have found that the only way to get the demo to compile is with these changes:

With these changes I could get a working executable about 4 weeks ago, but now I get this error when building the demo:

collect2: error: ld returned 1 exit status
Error: /usr/bin/gcc failed with status: 1

So it almost builds but is now just missing the ModuleInfo for some reason. It would be cool if we could version out that code for version 5.5.1 (and other versions downloaded directly) so that users don't have to build Qt themselves. Or perhaps I am just doing something wrong...download a different version?

Thanks,
Kelly

Strange CMake error

Hey Elie, I ran into this weird error with cmake, after yesterdays updates, when it tries to generate the ldc-druntime.dir/link.txt (and the -debug.dir/link file also).

I was getting build errors where /bin/ar kept saying 'unrecognized file format' but that wasn't the real problem, the real problem was that the link.txt file had some stray backslashes in it like this:

/usr/bin/ar cr ../lib/libdruntime-ldc-debug.a  /home/wilsonk/Downloads/Calypso/build/runtime/_\
_cpp-__cxxabiv1-__base_class_type_info.o /home/wilsonk/Downloads/Calypso/build/runtime/__cpp-_\

o /home/wilsonk/Downloads/Calypso/build/runtime/__cpp-_Unwind_Reason_Code.o CMakeFiles/druntim\
e-ldc-debug.dir/druntime/src/core/stdc/errno.c.o

So it almost seems like there is a string copy that is failing after a certain length? Weird. I am using cmake-2.8.12.

It looks like issue #16 is back

Hello Elie,

I am getting the same issue as #16 again after yesterdays commits...or at least I think it is the same issue:

/usr/include/x86_64-linux-gnu/sys/stat.h(209): Error: function cpp.core.sys.posix.sys.stat.stat conflicts with static import cpp.core.sys.posix.sys.stat.stat at /usr/include/x86_64-linux-gnu/bits/stat.h(46)

I ran into this when testing the dlib demo I have again, but it also happened with a couple other test libs I have set up. I just thought I would let you know. The Qt demo also isn't compiling for me:

semantic3 QOpenGLDebugMessagePrivate

#4 0x7a04b1 TemplateInstance::tryExpandMembers(Scope*) (/home/wilsonk/Downloads/Calypso/build/bin/ldc2+0x7a04b1)
etc...

Maybe it works for you still? just wanted you make sure you knew about this stuff and that we have a record of it.

Thanks,
Kelly

Calypso won't link after ldc-0.16.1 update

Hey Elie,

I just did a pull (which went fine) and a submodule update and then tried to remake Calypso by removing the entire bulid dir and running cmake. It all compiles but it just won't link. I get dozens of undefined references when trying to link ldc2? Some examples:

Missing libs? I wonder how your version built? I am still on llvm-3.6.2 if that matters?

        The module 'test_calypso' is already defined in '/tmp//main'.

Build failure problem with CLANG_INCLUDE_DIRS

After the problem I reported in issue #23 I am still having problems building. That issue only solved the cmake execution, but when I run make, I got:

[samjnaa:~/sr/_repos/git/_dlang/calypso/build] make
...
[  8%] Building CXX object CMakeFiles/LDCShared.dir/dmd2/cpp/cppexpression.cpp.o

                from /home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6/tools/clang/include/clang/AST/ASTContext.h:18,
                from /home/samjnaa/sr/_repos/git/_dlang/calypso/dmd2/cpp/astunit.h:18,
                from /home/samjnaa/sr/_repos/git/_dlang/calypso/dmd2/cpp/cppexpression.cpp:3:
/home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6/tools/clang/include/clang/AST/ASTFwd.h:22:35: fatal error: clang/AST/DeclNodes.inc: No such file or directory
#include "clang/AST/DeclNodes.inc"
                                ^
compilation terminated.

So I look for the required file:

[samjnaa:~/sr/_repos/git/_dlang/calypso/build] find /home/samjnaa/sr/_repos/svn/_llvm/ -name "DeclNodes.inc"
/home/samjnaa/sr/_repos/svn/_llvm/build/tools/clang/include/clang/AST/DeclNodes.inc

Then I changed the CLANG_INCLUDE_DIRS in the cmake command to use the built include dirs:

[samjnaa:~/sr/_repos/git/_dlang/calypso/build] cmake .. -DLLVM_SOURCE_PATH="/home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6" -DCLANG_INCLUDE_DIRS="/home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6/build/tools/clang/include"
-- LDC version identifier: cfcae2
-- Using path for Intrinsics.td: /usr/lib/llvm-3.7/include
-- Configuring done
-- Generating done
-- Build files have been written to: /home/samjnaa/sr/_repos/git/_dlang/calypso/build

But now the make is looking for a header which is in the source include dirs:

[samjnaa:~/sr/_repos/git/_dlang/calypso/build] make
...
[  8%] Building CXX object CMakeFiles/LDCShared.dir/dmd2/cpp/cppexpression.cpp.o

                                ^
compilation terminated.
...
[samjnaa:~/sr/_repos/git/_dlang/calypso/build] find /home/samjnaa/sr/_repos/svn/_llvm/ -name "ASTContext.h"
/home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6/tools/clang/include/clang/AST/ASTContext.h

Then I try to specify both, using : (colon) as the path separator on my platform:

[samjnaa:~/sr/_repos/git/_dlang/calypso/build] cmake .. -DLLVM_SOURCE_PATH="/home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6" -DCLANG_INCLUDE_DIRS="/home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6/build/tools/clang/include:/home/samjnaa/sr/_repos/svn/_llvm/llvm-3.6/tools/clang/include"
-- LDC version identifier: cfcae2
-- Using path for Intrinsics.td: /usr/lib/llvm-3.7/include
-- Configuring done
-- Generating done
-- Build files have been written to: /home/samjnaa/sr/_repos/git/_dlang/calypso/build

But still no fruit and I'm getting the same error. I tried using the semicolon and curiously I get the previous error. I'm not sure what else to try...
