Hi all,
I am a bit confused about what is going on with selection of compiler on
Snow Leopard for the apbs port. It is taking clang for C but llvm-g++-4.2
for C++, and the latter does not work for this port. If clang++ were used I
think it would work. Why is that not being selected? Why is an inconsistent
pair of C and C++ being used?
Thanks,
David
In the Portfile I have
compiler.blacklist macports-gcc-4.4 macports-gcc-4.5 macports-gcc-4.6 \
macports-dragonegg-3.3 macports-dragonegg-3.4
gcc-4.2 llvm-gcc-4.2 apple-gcc-4.2 macports-llvm-gcc-4.2
The failing buildbot output:

Selected parts of that:
