The problem is in boost/numeric/conversion, which should throw exceptions with boost::throw_exception, not literal throw, to aid compilation with -fno-exceptions. I'm spinning a build that should fix this.
Note that boost::throw_exception is then defined in the client. In rocs, it's in src/Plugins/dotParser/dotgrammar.cpp:
namespace boost
{
void throw_exception(std::exception const &) {}
}
But, from boost documentation, "callers of throw_exception are allowed to assume that the function never returns; therefore, if the user-defined throw_exception returns, the behavior is undefined". Just FYI.
FWIW, I think it sucks that we're building KDE with -fno-exceptions when the rest of Fedora is using -fexceptions even for C code. We should probably patch the kdelibs CMakeLists.txt to kill that -fno-exceptions use. Build requeued, https://koji.fedoraproject.org/koji/taskinfo?taskID=3224594 in the meantime, I would tend to agree with kevin's sentiments about exceptions. anyone interested to poke kde upstream about that? new build looks like a winner, thanks! |
