Hi, The dev-lang/nettle-3.9.1-r1 ebuild contains this code: # https://git.lysator.liu.se/nettle/nettle/-/issues/7 if use cpu_flags_ppc_altivec && ! tc-cpp-is-true "defined(__VSX__) && __VSX__ == 1" "${CPPFLAGS}" "${CFLAGS}" ; then ewarn "cpu_flags_ppc_altivec is enabled, but nettle's asm requires >=P7." ewarn "Disabling, sorry! See bug #920234." myeconfargs+=( --disable-power-altivec ) fi This unconditionally disables altivec because the invocation of tc-cpp-is-true is incorrect. tc-cpp-is-true quotes the arguments to the compiler so by passing a quoted CPPFLAGS and CFLAGS, the compiler gets exactly two quoted arguments instead of having them split by the shell as expected. In my case, the compiler invocation in tc-cpp-is-true looks like this: powerpc64le-unknown-linux-gnu-gcc -E '' '-O2 -pipe -mcpu=power9 -mtune=power9' -P - which is an invalid compiler command so the test always fails. Just removing the unwanted quotes from the ebuild is sufficient to avoid this problem.
