Another one like libssp. In libstdc++-v3's configure.ac, we see this:
# This depends on GLIBCXX CHECK_LINKER_FEATURES, but without it assumes no. GLIBCXX_ENABLE_SYMVERS([yes]) The comment lies. If we haven't yet checked the linker features, it will check them, and configure will fail in a combined build because newlib/libgloss hasn't yet been installed. Since we already check for cross compiling, I've been using this conditional instead: if test x"$gcc_no_link" = xyes; then true; else # This will run GLIBCXX CHECK_LINKER_FEATURES, so we can't use it if we can't # build executables. GLIBCXX_ENABLE_SYMVERS([yes]) fi but of course this will drop support for cross compiled linux targets having symbol versioning. Suggestions?
