Building ACE on AIX with IBM Open XL C/C++

[Sergio Romana]

Hi Johnny, thanks you for responding.  I have tried 6.5.21 but it fails as the Open XL C/C++ compiler is very different to the IBM XL C/C++ compiler, both in terms of the actual compiler executable names and the options recognised by the compiler. I have tried amending the make include file to use the new compiler executable names and to change the compiler options to the Open XL C/C++ equivalents.

ibm-clang++_r -fexceptions -m64 -frtti -g -fsanitize=integer-divide-by-zero,null -DACE_AIX_VERS=703 -I/home//ACEAix/ACE.6.5.21_c1/ACE_wrappers -DACE_NO_INLINE -I.. -DACE_BUILD_DLL -DACE_AS_STATIC_LIBS -c -o .obj/ACE.o /home/ACEAix/ACE.6.5.21_c1/ACE_wrappers/ace/ACE.cpp
In file included from /home/ACEAix/ACE.6.5.21_c1/ACE_wrappers/ace/ACE.cpp:5:
/home/ACEAix/ACE.6.5.21_c1/ACE_wrappers/ace/Auto_Ptr.h:77:12: error: no member named 'auto_ptr' in namespace 'std'
   77 | using std::auto_ptr;
      |       ~~~~~^
1 error generated.

I think I’ll need to dig into this a bit more to see what #defines I need to set in the config header file.

Hi,

Have you tried to compile ACE 6.5.21 with the newer IBM compiler, maybe that is the easiest to get something to work again on AIX.

Hello, I currently run an older version of ACE (6.5.21) on AIX that was built using XL C/C++ V11.1.  I’m trying to move to AIX 7.3 with clang based IBM Open XL C/C++ V17.1.3.  I notice that since version 7.1.0 that AIX versions of the config and make include files are no longer provided. The config/make files supplied with older versions of ACE are for the IBM XL C/C++ compiler.

Has anyone built ACE (any version) on AIX using the clang based Open XL C/C++ compiler?

Any help would be greatly appreciated.

Thanks
