You say to use libkrb5 for the valid_cksumtype error, which libkrb5 file do I use? I've tried libkrb5.a, libkrb5.so, and libkrb5.so.3 and the valid_cksumtype error remains. Also, is this the correct syntax? -L/usr/kerberos/lib/libkrb5.a I also tried -L/usr/kerberos/lib/libkrb5 but that didn't work either. Thanks! You don't specify any libs after the -L/usr/kerberos/lib . You can check which libs contain a given ref with 'nm <lib> | grep <ref>'. E.g., valid_cksumtype is in libkrb5.
