Problem in the Linux build (fix attached)

Postby godlike » Mon May 11, 2015 4:12 pm

Hi,

Pulled the latest revision of Newton and tried to build on my machine with Ubuntu 14.04. Unfortunately there are multiple failures.
- It seems the SSE4 include header is not actually included (smmintrin.h)
- The -msse4 is missing from the compiler args
- For some reason wxWidgets that my system has installed (ver 3.x) complains about the C++ standard. So I added -std=c++11 to the demosSandbox/CMakeLists.txt

Patch that fixed my build here: http://ancient-ritual.com/tmp/fix_linux_build.diff

PS: The forum doesn't allow uploading .diff or .patch or .txt files

To be fully coherent with the current defines, maybe the SSE4 include (smmintrin.h) should be ifdefed with DG_SSE4_INSTRUCTIONS_SET:
Code: Select all
#ifdef DG_SSE4_INSTRUCTIONS_SET
  #include <smmintrin.h>
#endif

I think Julio mentioned somewhere that he is planning to drop SSE prior to ver 4. So, it's going to be SSE4.x or no-SSE. Anyway, this part of dgTypes.h probably needs some cleaning because the SSE headers are guarded by this:

Code: Select all
#if (defined (_POSIX_VER) || defined (_POSIX_VER_64) || defined (_MINGW_32_VER) || defined (_MINGW_64_VER))


and this doesn't take into account the DG_SCALAR_VECTOR_CLASS or something related to SIMD
