Description Sergei Trofimovich gentoo-dev 2020-05-30 08:22:17 UTC
On sys-devel/gcc-config[-native-symlinks] system fribidi fails to build in configure phase as:

"""
...
checking size of void *... 4
checking size of wchar_t... 4
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in `/tmp/portage/dev-libs/fribidi-1.0.9/work/fribidi-1.0.9-abi_x86_32.x86':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
"""

sys-devel/gcc-config[-native-symlinks] removes default 'cc' and 'gcc' symlinks and relies on ebuilds passing CC/CXX variables.

In this case CC_FOR_BUILD variable is not set in the ebuild.

The following seems to be enough to get fribidi going again:
