[LAD] can't build libffado 2.2.1 under gentoo

Hello, i'm trying to build libffado from proaudio overlay. The problem seems to be in ffado itself. Somewhat long time ago (about year) i could install it, but now i have following problems on compilation: - First, it seems, that it now uses more modern language features: the specified option --std=c99, added by one of ebuild's patch, as well as without any options (tried to build tarball with) gives long error list. - With compiler flag --std=c++11 compilation continued for relatively long time, but then failed with following errors: http://pastebin.com/hkttBN9X there seems to be one common feature: definition with "quadlet_t" argument fails to overload same def with "byte_t" arg. I looked to src/libutil/cmd_serialize.h, and there are four (with original) variants for each functions... i don't understand, why only quadlet_t - typed variant fails, while others proceed. What i found yet is that this type is defined in raw1394 headers: $ grep -r 'quadlet_t;' /usr/include /usr/include/libraw1394/raw1394.h:typedef u_int32_t quadlet_t; And what is interesting, when i tried to build from tarball manually: $ scons -DCOMPILE_FLAGS='--std=c++11' ... that flag was not even passed to g++, so thanks for gentoo S). ------------- $ gcc --version gcc (Gentoo 4.9.3 p1.5, pie-0.6.4) 4.9.3
