Hi Arlind,

No, if you do have the build.conf, it will be considered automatically
unless you do not have SCons installed. The automatic detection is more
relevant for building the extension. But in your case it doesn't reach
that point. I assume that you do not have SCons installed? That would
explain, why the build.conf is ignored.
Another thing regarding your first mail. It seems that the function
determineCompiler(...) doesn't work reliably in your case. There are 2
things you could try:
1. Change the order in the candidate list of compilers, but I doubt that
would work, as for some reason the above named function doesn't work
properly.
2. In setup.py you could replace:
cppcompiler = determineCompiler(candidates)
with
cppcompiler = "g++-4.8"
Good luck,
Max
