When compiling GCC is being hard-set -march=pentiumpro and of course this leads to failure given my environment is also setting -m64 causing cc1plus to yield: cc1plus: error: CPU you selected does not support x86-64 instruction set Reproducible: Always Steps to Reproduce: 1. 2. 3.
All the myth plugins need to have their src_compile() function modified. The code local cpu="`get-flag march || get-flag mcpu`" if [ ! -z "${cpu}" ] ; then sed -e "s:pentiumpro:${cpu}:g" -i "settings.pro" || die "sed failed" fi Should be replaced with if [ "${ARCH}" == "amd64" ]; then sed -e "s:-march=pentiumpro::" -e "/DEFINES += MMX/d" -i settings.pro else local cpu="`get-flag march || get-flag mcpu`" if [ "${cpu}" ] ; then sed -e "s:pentiumpro:${cpu}:g" -i "settings.pro" || die "sed failed" fi fi (In fact it is adding three lines before and one after..) This, and adding ~amd64 to the keywords make at least mythdvd mythweather mythgallery and mythvideo build.
Fixed in 0.16. thanks
