seems to be due to this : http://sources.gentoo.org/viewcvs.py/gentoo-x86/eclass/flag-o-matic.eclass?r1=1.117&r2=1.118 If I apply this to the ebuild : - emake CC="$(tc-getCC)" || die + emake CC="$(tc-getCC)" CFLAGS="${CPPFLAGS} ${CFLAGS}" || die it compiles fine, but without it, it won't since it ignores CPPFLAGS @mike: is it the correct way of supporting cppflags here ? that's the only way I can think of now, but then, why changing the behavior of append-lfs-flags ?
Created attachment 126106 [details] mpglen-0.1.ebuild doing that would be an acceptable fix, but i think the overall ebuild could be greatly simplified
thanks ! commited. I just added this (plus relevant inherit): src_compile() { tc-export CC emake || die "emake failed" } so that it calls gcc with its full name rather than "cc"
