Building freeradius 2.2.3 configured with --with-system-libtool fails with the error message unable to infer tagged configuration when the system libtool was built using a different compiler from the one being used to build freeradius now.
unable to infer tagged configuration
The fix is to use --tag=CC or --tag=CXX, as applicable, every time you invoke libtool with --mode=compile or --mode=link.
Here is the patch I committed to MacPorts to fix this problem:
Perhaps you could include it in your next release.
OK. This kind of nonsense makes me happy we moved away from libtool in v3. We spent way too much time fighting with it, instead of actively developing FreeRADIUS.
Patch to use --tag=CC. Fixes #497
