gpgme 1.7.0: no type named 'shared_ptr' in namespace 'std'

[mojca (Mojca Miklavec)]

Installing gpgme 1.7.0 fails on 10.7 with:

/bin/sh ../../../libtool  --tag=CXX   --mode=compile /usr/bin/clang++ -std=c++11 -DHAVE_CONFIG_H -I. -I../../..  -I../../../src -I/opt/local/include -I/opt/local/include -DBUILDING_GPGMEPP -I/opt/local/include  -pipe -Os -stdlib=libstdc++ -arch x86_64 -MT context.lo -MD -MP -MF .deps/context.Tpo -c -o context.lo context.cpp

This might be connected with libstdc++ (i.e. no proper support for C++11), but I didn't try to investigate any further yet.

Yes, it looks like it requires libc++. Guess I should add the cxx11 portgroup.

[oliver.ruben@…]

I can confirm the same problem on 10.8.5.

[dbevans (David B. Evans)]

Workaround committed in r153382, cpp bindings are only built if libc++ is the default C++ stdlib (typically 10.9+), C language API is built in all cases. Now builds on all buildbots 10.6+.
