I specified the clang as compiler for webkit-gtk via /etc/portage/bashrc script: /etc/portage/bashrc [ -r ${ROOT}/etc/portage/package.clang ] || return 0 while read -a target; do if [ "${target}" = "${CATEGORY}/${PN}" ]; then export CC="clang" export CXX="clang++" break fi done < ${ROOT}/etc/portage/package.clang /etc/portage/package.clang net-libs/webkit-gtk Build fails with error: typedef redefinition with different types ('char *' vs 'WTF::String'), and it looks like clang can't handle namespaces properly, if I'm not mistaken. GCC compiles webkit-gtk right. Reproducible: Always Complete build log: http://ompldr.org/vOXdkaw/build.log
1) Please post your `emerge --info' output. 2) Please attach the entire build log. Note: As far as I can tell, clang is far from being a finished, reliable replacement for gcc.
