cling-feedstock's Issues

Misspelled option

I believe -DINSTALL_RPATH_USE_LINK_PATH=ON should be removed or changed to -DCMAKE_INSTALL_RPATH_USE_LINK_PATH=ON; it is being ignored in its current spelling, I believe.

Duplicate builds of cling

We failed to bump the build number in a cling rebuild, which ended up with some platforms having two builds of cling with the same version and build numbers, but not the same hash.

We should delete the newest builds of cling 0.7 with build number 2 (only those corresponding to platforms for which we already had one), namely

linux-64/cling-0.7-hf817b99_2.tar.bz2
linux-aarch64/cling-0.7-h6293a0b_2.tar.bz2

Issues finding headers

The following was done inside a the official miniconda3 docker container that is based on Ubuntu and has almost nothing installed:

$ docker run --rm -it continuumio/miniconda3 bash

Create an environment:

$ conda create --name test-cling -c conda-forge/label/gcc7 -c conda-forge -c defaults python=3.7 cling
$ source activate test-cling

Cling then fails to find standard headers and segfaults when I try to compute 2+3:

If I manually set the include directories instead it seems okay:

Windows `cling` crashes when trying to print a value

I read the conda-forge documentation and could not find the solution for my problem there.

Issue:

cling crashes when it tries to print a value.

I open the issue here because this occurs on my Windows machine, but not on the Ubuntu WSL. As they don't provide a precompiled Windows binary, I think the problem is from the building system of conda-forge.

Reproduction:

Install cling from conda-forge
Open a cmd and start cling
int a = 1 (no semicolon)

Expected Behavior:

It prints (int) 1.

Actual Behavior:

It crashes with errors as below.

Note:

If the statement does not print a value, like int a = 1;, then there's no problem.

If the value is printed using C++ functions, like printf, then it can print without any issue.

Windows exception handling

It seems that the windows support of cling is incomplete and that IO operations are not yet available. We reached out to the upstream team on this issue.

Marking "cling v0.6 build 0" as broken

Hello, @conda-forge/core, would it be possible to mark some cling builds as broken? Namely cling 0.6 build 0 on all platforms:

cling-0.6-h1a24767_0.tar.bz2
cling-0.6-h7475705_0.tar.bz2
cling-0.6-he513fc3_0.tar.bz2

Linux build glibc compatibility

Launching the current build of cling produced by conda-forge yields:

Warning in cling::IncrementalParser::CheckABICompatibility():
  Possible C++ standard library mismatch, compiled with __GLIBCXX__ '20140120'
  Extraction of runtime standard library version was: '20160609'

and later on, the interpreter errors on IO operations. (Linux platform...)

This error does not occur when building the recipe locally since the glibc version is consistent.

cling has tight constraints in terms of glibc version match between what was used at link time and runtime.
We could prevent this by building cling with conda's gcc and libgcc instead of the one of the build container (this might require to build the entire llvm/clang stack like this). Besides, for the resulting cling binary to support modern C++, we would need a more recent version of gcc.

EDIT: the approach with gcc is blocking on ContinuumIO/anaconda-issues#1465

ERROR in cling::executePrintValue(): cannot pass value!

Using python=2.7 allows me to create a C++11 notebook.
The example from https://github.com/SylvainCorlay/cling-binder does not work however:

It might be related to #1 since I see the following in the console:

[I 23:57:33.655 NotebookApp] Kernel restarted: 2725a98c-a398-4032-a630-ce9e38f3f294

  Extraction of runtime standard library version was: '20160609'
[ClingKernelApp] ERROR | UNKNOWN MESSAGE TYPE: u'comm_open'

[OSX] The new build with the root flavor of clangvariant is not functional

With the latest build on OSX, starting cling shows the following error message.

/Users/scorlay/miniconda3/include/c++/v1/stdlib.h:94:15: fatal error: 'stdlib.h' file not found
#include_next <stdlib.h>

Then, doing anything that does io results in the following

/Users/scorlay/miniconda3/include/c++/v1/stdlib.h:94:15: fatal error: 'stdlib.h' file not found
#include_next <stdlib.h>
              ^~~~~~~~~~

cling 0.4

Hello,

are you planning bringup cling 0.4 version into conda?

Thanks.

update circle

@conda-forge-admin, please update circle

cling is not properly worked in Windows conda python 2.7

I use conda python 2.7, install cling by this command in Window system:

conda install -c conda-forge cling

Jupyter notebook will be crashed, after I create a new C++ notebook, not matter C++11, 14 or 17.

Traceback (most recent call last): File "~\AppData\Local\Anaconda2\Scripts\jupyter-cling-kernel-script.py", line 2, in <module> from clingkernel import main File "~\AppData\Local\Continuum\Anaconda2\lib\site-packages\clingkernel.py", line 24, in <module> from fcntl import fcntl, F_GETFL, F_SETFL ImportError: No module named fcntl

ImportError: No module named 'clingkernel'

Thank yout @SylvainCorlay for working on this!
I just tried to install this in my conda environment:

$ conda install cling
...
The following NEW packages will be INSTALLED:

    clangdev:      3.9.1-cling_3 conda-forge [cling]
    cling:         0.3.post-0    conda-forge [cling]
    cling-patches: 1-0           conda-forge
    libcxx:        3.9.1-0       conda-forge
    llvmdev:       3.9.1-cling_4 conda-forge [cling]
    system:        5.8-2         defaults   
...

however, when I create a C++11 notebook the kernel dies with the following printed to the console:

[I 20:15:10.037 NotebookApp] Creating new notebook in

    from clingkernel import main
ImportError: No module named 'clingkernel'

and there doesn't seem to be any "clingkernel" in conda-forge channel:

$ conda install clingkernel
...
PackageNotFoundError: Package not found: '' Package missing in current linux-64 channels:

Close matches found; did you mean one of these?

Setting include path on cling on windows to avoid visual studio headers

[*] I read the conda-forge documentation and could not find the solution for my problem there.

Issue:

Environment (conda list):

$ conda list

Details about conda and system ( conda info ):

$ conda info

I installed cling on windows with conda-forge channel. The installation succeeded.
I have visual studio 2022 preview installed on my machine.
When I try to include something such as or , cling searches in visual studio include directory and reports some errors.
There is a way to set cling include path without searching isual studio headers files?
I have cling 0.8 on windows 10 64 bit.
