Re: OS X 10.10 build problems w/ typegen

Hi Sylvain, all,

I tried this in the meantime but I can only build gccxml with gcc 4.2 or
clang, all other versions of gcc that macports provide result in a compile
error like:

:info:configure -- Searching 16 bit integer

:info:configure -- Looking for stddef.h

:info:configure -- Looking for stddef.h - not found

:info:configure -- Check size of unsigned short

:info:configure -- Check size of unsigned short - failed

:info:configure -- Check size of unsigned int

:info:configure -- Check size of unsigned int - failed

:info:configure -- Check size of unsigned long

:info:configure -- Check size of unsigned long - failed

:info:configure CMake Error at
/opt/local/share/cmake-3.1/Modules/TestBigEndian.cmake:51 (message):

:info:configure   no suitable type found

:info:configure Call Stack (most recent call first):

:info:configure   GCC/config_cmake/CMakeLists.txt:158 (TEST_BIG_ENDIAN)

:info:configure

:info:configure

:info:configure -- Configuring incomplete, errors occurred!


If I compiled with clang I cannot let it use one of the gcc compilers:

export GCCXML_COMPILER=g++-mp-4.3 (tried various mp versions)

gccxml Structs.hpp

cc1plus: error: unrecognized command line option "-stdlib=libc++"

error: could not identify compiler via -E preprocessing

Support item
ERROR_unsupported_compiler_in_gxConfiguration_GetCompilerId/find_flags is
not available:

 checked
"/opt/local/share/gccxml-0.9/ERROR_unsupported_compiler_in_gxConfiguration_GetCompilerId/find_flags"

Could not determine GCCXML_FLAGS setting.


Does anyone have orogen/typegen working with gccxml on a OSX 10.10 system?
If so, could you please share how you did it?

Is the clang version ready for testing? I would be happy to try it on my
setup (Ubuntu 14.04, Mint 17, OSX 10.9 and 10.10).


Regards,


Ruben
