Hi everyone, I just want to make clear that this is *not* specific to c++11 projects. Even if you don't use any c++11 features, clang can't link against the library. Try compiling my example code (which is valid c++98) with $ g++ -std=c++98 -o options options.cpp -lboost_program_options $ clang++ -std=c++98 -o options options.cpp -lboost_program_options The results are the same - works on gcc, fails to link on clang on sid, while both commands used to work on stable. If I understand the consequences of this failure right, this will severely impact the usefulness of clang++, since it will start failing to link against *any* c++ library compiled by recent g++, breaking unchanged and valid user code - be it c++11, c++03 or c++98. I don't think this is that much of an issue on sid - after all, it's called "unstable" for a reason - but it might be a showstopper for stable, if clang++ is to be an alternative for g++. - Danny
