| I think I have found what your problem is with linking to a custom heimdal
|
| heimdal's krb5-config returns this:
|
| metze at COMPILIX:~> krb5-config --libs
| -L/usr/lib -lkrb5 -lasn1 -lcrypto -lroken -lcrypt -lresolv
|
| or this for a custom version
|
| metze at COMPILIX:~/samba4/samba4-heimdal/bin> ./krb5-config --libs
| -L/home/People/metze/samba4/samba4-heimdal/lib -lkrb5 -lasn1 -lcrypto
| -lroken -lcrypt -lresolv
|
|
| and MIT krb5-config returns this
|
| metze at routox:~> krb5-config --libs
| -L/usr/lib -Wl,-rpath -Wl,/usr/lib -lkrb5 -lk5crypto -lcom_err
|
| so heimdal is missing the -Wl,-rpath -Wl,<LIBPATH>
|

| system libs (-Wl,-rpath... is for this one)

I have a patch for this, but I think -Wl,-rpath is maybe not portable to all linkers, we need to
check that...

But it should fix your current problem, and only add the path flags when they are not the system default
