Here's the Makefile I use to build my program:

krb5ver:
        gcc -Wall -c -I/usr/local/kerberos/include krb5ver.c
        gcc -o krb5ver krb5ver.o  -L/usr/local/kerberos/lib -lk5crypto -lkrb5 
-lcom_err

If you install libraries in a non-standard location that the dynamic linker doesn't know about, you have to encode the path to the libraries into the binary. Adding -R/usr/local/kerberos/lib will probably fix the problem.

Russ,

Thanks, that fixed it! I must say, I didn't even know about the -R option to gcc and can't find it in the gcc man page. What does -R do anyway?

I had just assumed that the '-L/usr/local/kerberos/lib' would be sufficient to tell the linker where to find the libraries. Why did only libk5crypto have a problem and not, for example, libkrb5?

(My knowledge about linking is clearly inadequate).

Thanks again.

Mike
