I've been avoiding doing either, though, because usually MIT is available as the system library and that krb5-config will be found first, so I don't think adding /usr/heimdal/bin to the search path will actually help anything. > We also probably need to do better about detecting the proper header vs > detecting libraries, apparently... (I haven't looked at this in detail, > maybe this is better in master or something) I'm able to build my Kerberos packages with both Heimdal and MIT installed on the system on different paths, so I know that the macros work and produce the right flags. However, you do have to be very careful about what other flags you pass in and the ordering of flags. Generally, you need to put KRB5_CPPFLAGS before anything else in your CPPFLAGS setting, and likewise with KRB5_LDFLAGS and LDFLAGS. Otherwise, if you have anything that (erroneously) adds -L/usr/lib or -L/usr/lib64 to your link flags, you will pick up the default Kerberos library instead of the one that you wanted. Unfortunately, this is to some extent an unavoidable limitation in the way that one specifies paths to a compiler. There isn't any way to portably pass in a -L flag that applies only to a specific -l flag but not to any other, so if you have multiple libraries that you're linking with at different paths, you can create situations where it's actually impossible to specify exactly the libraries you want. -- Russ Allbery ([email protected]) <http://www.eyrie.org/~eagle/> _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
