Can't build toolchain on Linux (Ubuntu feisty 64-bit) about iphone-dev HOT 24 OPEN

I've heard of this from several people. One said that they would get me a 
patch. As I don't have a 64-bit system, 
I'll have to wait on that.

64bit People!
If your GCC supports the -m32 flag just compile odcctools with it (add to CFLAGS
environment variable) and it will work flawlessly.

Thanks for the great toolchain.

64bit People!

The above comment helped my compile, but it still gacked and died until I also 
added
-m32 to the LDFLAGS env var.

export CFLAGS="-m32"
export LDFLAGS="-m32"

The compile finished without complaint -- still seeing whether it's actually 
going to
work, ymmv.

Thanks avnerus for the push in the right direction.

Thanks, emersonrp. I've added a note in the [[Portability]] section of the wiki.

I've made some changes to odcctools to get it building on 64bit, but the 
resulting
binaries aren't working properly (I tested the arm nm against the binary libs 
of csu
and it can't read symbols.)  So, more work to do...

I'm on Ubuntu Gutsy x86_64, and the -m32 stuff doesn't help.  I get the error 
message:

checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler
cannot create executables
See `config.log' for more details.

So you guys didn't tell me of all the stuff I'd need to get:

-- subversion
-- csh
-- libc6-dev
-- flex
-- m4
-- bison
-- pax
-- g++
-- patch

On my ubuntu amd64 system I do:
export CFLAGS="-m32"
export LDFLAGS="-m32"
./configure --target=arm-apple-darwin --disable-ld64
and get:
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... arm-apple-darwin
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler
cannot create executables

any ideas?

sudo apt-get install gcc-multilib fixed that, now onto make giving me:

I had exactly the same problem. I have installed 32 bit gcc and make; make 
install finished just fine 
after that.

when I find the 32 bit gcc and make?
thank you

The 32-bit gcc can be obtained by installing gcc-multilib.  I had to install
gcc-4.2-multilib because gcc-4.3 was giving me errors.  However, it's the 
multilib
package that provides the necessary compiler.

After installing that, you should be able to set the CFLAGS and the LDFLAGS to 
"-m32"
and compile properly.  I have yet to see if the toolchain works, but the 
compilation
completed successfully.

Ubuntu 8.04 64-bit

with :

export CFLAGS="-m32"
export LDFLAGS="-m32"

../../../odcctools/ar/archive.c: In function ‘open_archive’:
../../../odcctools/ar/archive.c:122: warning: implicit declaration of function 
‘flock’
At top level:
cc1: error: unrecognized command line option "-Wno-long-double"
make[1]: *** [archive.o] Error 1

OK so I get 
At global scope:
cc1plus: warning: unrecognized command line option "-Wno-long-double"
make[1]: *** [ld.o] Error 1
make[1]: Leaving directory `/root/iphone-dev/build/odcctools/ld64'
make: *** [ld64] Error 2

When compiling with --enable-ld64, I'm running 32bit ubuntu 9.04, but I 
understand
doing that is a requirement to get the toolchain working for 3.0?

Anyways, when I do --disbable-ld64, make runs just fine.

(Same Comment 17)

The solution offered in Comment 15  by avikstrange, Jan 19, 2009 worked for me.
* Linux version 2.2.26-2-686 (Debian 2.6.26-17)
* (gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25))

I initially "installed" gcc 4.2 by simply running "apt-get install gcc-4.2". 
However,
when you run "gcc --version" in the command-line, it still prints version 4.3, 
to
"fix" this I did:

#Double check you have gcc 4.2, you should see "gcc-4.2" executable
ls -al /usr/bin|grep gcc

#Remove existing symbolic link to gcc 4.3
rm /usr/bin/gcc

#Link to 4.2
ln -s /usr/bin/gcc-4.2 /usr/bin/gcc

#Verify this worked
gcc --version

Should now print out something like "gcc (GCC) 4.24 (Debian 4.2.4-6)"

At this stage I had already exported LDFLAGS and CLFAGS manually so I don't 
know if
this helped; I also used configure with --disable-ld64. After performing this 
make
worked fine.

Hope this helps...

I had to do the last comment but also do it with apt-get install g++-4.2 and ln 
-s
/usr/bin/g++-4.2 /usr/bin/g++ after getting a g++ command not found.

hi, see issue 221

There were 2 "big" bugs in the odcctools which caused the trouble with native 
64bit:

1. in include/foreign/machine/vm_types.h: the vm_address_t was forced to 32bit, 
but its used for storing memory addressing (->> CRASH)
2. in libmacho/arch.c: in the NXGetArchInfoFromCpuType you returned a non 
static pointer on a static table - the driverdriver tried to change the table 
(->> CRASH)

oh it's issue 212 ;) sorry

A positive feedback.

First making odcctools failed with conflicting types. I added CFLAGS=-m32 
LDFLAGS=-m32 option in configure. Then configure complains "configure: error: C 
compiler cannot create executables". After I installed 32bit version of libgcc, 
odcctools compiles successfully (with some warnings still).

see issue 212 - i've fixed the problems in the toolchain. With my patches, the 
toolchain is fully 64bit compatible and there's no need for the m32-flags / 
multilib-gcc anymore

Here is a patch set for building on linux with gcc and glibc.  I am not sure 
how many of these patches will work on different linux distros but on gentoo it 
solved all of the compile errors and explicit declarations as well as a ton of 
warnings due to the objc++ garbage sprinkled about.  I have not tired building 
with otool or an objc enabled compiler.  Hopefully someone finds some of these 
useful and incorporates them into the repository.

These have only been tested on x86_64 and you do not need to pass in -m32.  I 
compiled with the following:

./configure --prefix=/usr --build=x86_64-pc-linux-gnu 
--host=x86_64-pc-linux-gnu --target=i586-apple-darwin10 --mandir=/usr/share/man 
--infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc 
--localstatedir=/var/lib --libdir=/usr/lib 
--with-sysroot=/usr/i586-apple-darwin10 --enable-ld64

make && make install
