[pypy-dev] cppyy fails to build on gcc 5 and clang

[Ryan Gonzalez]

I think you misunderstood me. Your build log shows:

  

oberstet at thinkpad-t430s:~/scm/oberstet/scratchbox/cpp/capnproto/test1$ make
cpppypy  

CC=`which clang` \  
CXX=`which clang` \  
CXXFLAGS="-std=c++11 -stdlib=libc++" \  
LDFLAGS="-stdlib=libc++" \  
MAKE_NPROCS=4 \  
~/pypy-5.6-linux_x86_64-portable/bin/pip install --verbose PyPy-cppyy-backend  

  

  

I'm saying to _remove_  the `-stdlib=libc++` that's currently there.

libcxx from clang is not used. Seems a configuration mismatch: to use libcxx,  
the cmake machinery needs to be told to do so (-Dlibcxx=ON IIRC), as it's off  
by default.

these extra arguments to cmake, but should be possible. I don't think libcxx  
has been tested outside MacOS X, though.
