Bug#800492: libc++-dev: Missing __cxxabi_config.h in libc++-dev

[Xiangyu Liu]

Actually I found the __cxxabi_config.h in libc++abi-dev package ( 3.7.0-1
), and I installed libc++abi-dev. But it could not be found automatically
by /usr/include/c++/v1/cxxabi.h.
If I set CXXFLAGS += /usr/include/libcxxabi  then it did work. So my bug
report should be " Clang 3.7 can't find __cxxabi_config.h automatically
with libc++-dev & libc++abi-dev".
Anyway, let me keep it for libc++-dev.


Thanks,
Best Regards,
Ricky X.Y. LIU
