C++ compiler automatically adds -lstdc++ or -lc++ unless -nostdlib or -nostdlib++. Modern Clang converts -lstdc++ into -lc++ unless -nostdlib or -nostdlib++. xapian-bindings uses libtool which adds -nostdlib and uses autoconf to detect GCC which includes Clang due to __GNUC__ defined for compatibility. Why not use ports/packages where this is already solved? >From databases/py-xapian/Makefile post-patch: @${REINPLACE_CMD} -e 's|-lstdc++||g' ${WRKSRC}/configure Alternatively, replace -lstdc++ with -lc++ in Clang via environ(7) $ export CCC_OVERRIDE_OPTIONS='# s/stdc\+\+/c++/' # sh(1) style $ setenv CCC_OVERRIDE_OPTIONS '# s/stdc\+\+/c++/' # csh(1) stylehelp
