Problems compiling on gentoo

[siffland]

I would really like to get this compiled on gentoo (the portage overlay does not work). I have gotten around most issues but am stuck on this latest:

-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_CMAKE_CONFIG -D__VIDEOCORE4__ -U_FORTIFY_SOURCE -Wall -DHAVE_OMXLIB -DUSE_EXTERNAL_FFMPEG -DHAVE_LIBAVCODEC_AVCODEC_H -DHAVE_LIBAVUTIL_OPT_H -DHAVE_LIBAVUTIL_MEM_H -DHAVE_LIBAVUTIL_AVUTIL_H -DHAVE_LIBAVFORMAT_AVFORMAT_H -DHAVE_LIBAVFILTER_AVFILTER_H -DOMX -DOMX_SKIP64BIT -ftree-vectorize -DUSE_EXTERNAL_OMX -DTARGET_RASPBERRY_PI -DUSE_EXTERNAL_LIBBCM_HOST -isystem/var/tmp//usr/include -isystem/var/tmp//opt/vc/include -isystem/usr/arm-bcm2708-linux-gnueabi/sys-root/usr/include -isystem/var/tmp//opt/vc/include/interface/vcos/pthreads -isystem/var/tmp//usr/include/freetype2 -isystem/usr/include -isystem/opt/vc/include -isystem/opt/vc/include/interface/vcos/pthreads/ -isystem/usr/include/freetype2/ -I./ -Ilinux -Iffmpeg_compiled/usr/local/include/ -c OMXPlayerSubtitles.cpp -o OMXPlayerSubtitles.o -Wno-deprecated-declarations In file included from OMXPlayerSubtitles.cpp:23:0: Enforce.h:49:15: error: looser throw specifier for 'virtual const char\* Enforce_error::what() const' /usr/lib/gcc/armv6j-hardfloat-linux-gnueabi/4.5.4/include/g++-v4/exception:69:25: error: overriding 'virtual const char\* std::exception::what() const throw ()' Enforce.h:35:45: error: looser throw specifier for 'virtual Enforce_error::~Enforce_error()' /usr/lib/gcc/armv6j-hardfloat-linux-gnueabi/4.5.4/include/g++-v4/exception:65:13: error: overriding 'virtual std::exception::~exception() throw ()' make: **\* [OMXPlayerSubtitles.o] Error 1

I have not modified the Makefile at all and here is my modified Makefile.include

Any help would be appreciated. I updated my GIT repository last night and did a rpi-update to ensure the latest firmware.

Thanks,

You will have to use GCC 4.6 or above.

I've actually addressed this issue in Gentoo bugzilla: https://bugs.gentoo.org/show_bug.cgi?id=421683
