OK, I think we figured out why this is:
19:11 < Jeroen> given that krb is a library, it probably supports
programs which are multithreaded
19:11 < Jeroen> so it doesn't have to use pthreads
19:11 < Jeroen> only when pthreads is there, it has to do proper locking
19:11 < Jeroen> so it declares the symbols weak
19:11 < Jeroen> and checks whether they are available
19:12 < Jeroen> but because pthread_mutex_lock is an inline function
calling _pthread_mutex_lock
19:12 < Jeroen> and krb doesn't know about that
19:13 < Jeroen> there is a non-weak reference to _pthread_mutex_lock
I guess one option would be to patch krb5 to add weak pragmas for
_pthread_mutex_lock et al. The other option would be to change
libpthread to not have these inline functions. I will talk to the Hurd
maintainers about this, do you have an opinion whether a change in krb5
(at least for Debian) is feasable in the meantime?
cheers,
Michael
