| | Hi Andrew,
| |
| | 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>
| |
| | that means samba links fine to the custom libs (-L is for that) but at
| | runtime the loader uses the
| | 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

I have tested that on my SuSE 9.2 box and I  finally got an output like this
with the patch applied
