I don't know what the right fix is, but that's not it (libraries shouldn't go in LDFLAGS but in LDADD).

What error do you get, what commands do make/libtool end up running, and what platform are you on?

Ideally, please do "make -k -C src/check-compat" to get *all* the output and errors from src/check-compat. If you could attach your src/libtelepathy.la so I can see what libtool thinks it depends on, that'd also be helpful.

Hey,

I'm on Debian Sid, on x86, make -k -C outputs this:

don't mind asking for more info.

Amusingly enough, your FTBFS is because you're compiling without optimizations. As a result, the static functions that call into dbus-glib, but are never called, are not optimized away to nothing, and as a result linking against dbus-glib is needed (linking against telepathy-glib is not required though). I'll fix this in darcs.

Fixed in Darcs, will be in the next release.
