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

[Tobias Oberstein]

Hi Ryan,

with CXX=clang++ the build nearly finishes (I am a moron, sorry, clang 
isn't that clever), that is

	CC=`which clang` \
	CXX=`which clang++` \
	CXXFLAGS="-std=c++11" \
	MAKE_NPROCS=4 \
~/pypy-5.6-linux_x86_64-portable/bin/pip install --no-cache-dir 
--verbose PyPy-cppyy-backend

I get to

     [ 95%] Linking CXX shared library ../../lib/libCling.so
     make[3]: Verzeichnis 
„/tmp/pip-build-EJ5mSe/PyPy-cppyy-backend/builddir“ wird verlassen
[ 95%] Built target Cling

but then it fails compiling clingcwrapper.cxx.o

This is

oberstet at thinkpad-t430s:~/scm/oberstet/scratchbox/cpp/capnproto/test1$ 
clang++ --version
clang version 3.8.0-2ubuntu4 (tags/RELEASE_380/final)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

Thanks for your help!
Tobias
