My guess is that you're running afoul of the changes in the linker. It
used to be that the linker would implicitly link against the
dependencies of anything you linked with. Now it has to be explicit.
Also, make sure it's actually relinking here. If you are linking against
a pre-built binary that might have been linked to libtalloc 1.x, there
was an ABI change that you might be hitting.
Delivering value year after year.
Red Hat ranks #1 in value among software vendors.
