/usr/lib/libmp4v2.so: undefined reference to `std::ctype<char>::_M_widen_init() const@GLIBCXX_3.4.11' Looks like you upgraded GCC lately, and didn't rebuild your world Try recompiling at least libmp4v2
just update the system with emerge -e system emerge -e system emerge -e world emerge -e world I did try to do emerge -C libmp4v2 emerge faac wich pull in also libmp4v2 but the result is what you can see above
Actually looks more like a gcc-config problem: that error means that some of the libs are linked against a more recent libstdc++ than the linker finds. Try resetting selected gcc and check /etc/ld.so.conf.
Thx for pointing me up the gcc issue I'm fixing the issue stay tuned
fixed thanks again for the support
