Can't compile with clang #24

Closed aleixpol closed 8 years ago

I recently switched to building my software with clang, now icemon isn't compiling.

Here's the error message:

This is not only a problem for Clang.

This is related to the ABI switch in GCC 5 (see https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html)

Both Clang + GCC seem to assume C++11 ABI for the (static) icecc library; which has been compiled using the old ABI, though.

Trying to work out a patch for this...

@aleixpol: Please test

I confirm it fixes it. Thanks for looking into it!
