MacPorts sets `MACOSX_DEPLOYMENT_TARGET` in their build environment. This likely elides the insertion of the linker flags `configure` is meant to generate, but it seems to not hurt. Correct behaviour from the `configure` script probably shouldn't depend on the user setting environment variables to avoid misdetection of the OS version. _______________________________________________ gmp-bugs mailing list gmp-bugs@gmplib.org https://gmplib.org/mailman/listinfo/gmp-bugs
