Re: [libvirt] [PATCH] build: fix typos in configure-set makefile variable names

That sounds reasonable, if we're guaranteed always to have a libdl.
However, the fact that it's not needed on F12 suggests that we should
be adding it only when necessary (hence a configure-time test).
I guess the problem might lie in the way the VirtualBox driver's
dependencies are linked; didn't FC13/Rawhide move to use --no-add-needed
by default?
If that's the case you have two options:
- a bug in the VirtualBox driver's dependencies, that causes some of
the libraries not to link to libdl;
- the VirtualBox driver *does* need libdl, but never linked it in by
itself as it relied on the --add-needed behaviour.
Easy way to test this is to try configuring on Rawhide with
LDFLAGS="-Wl,--add-needed" and see what happens… if it builds fine, it's
the latter.
On the other hand, you do have one problem: libdl is only present in
glibc/uclibc, as other C libraries have it part of the base library, so
I'd suggest adding a configure test.
If Richard can confirm whether it's the case, I should be able to write
one fairly quickly, I hope, as I have something similar laying around.
