I think the answer is fairly straightforward: the above link line does not include "-ldl" so libdl is not linked in, and the reference is indeed undefined. This may have worked previously with indirect linkage (i.e. one of the other libraries linked to libdl either directly or indirectly). Either way, it's the configure test that's broken, not your system! This is how I check for dlopen: AC_CHECK_LIB(dl, dlopen, [DLOPEN_LIBS="-ldl"]) Regards, Roger -- .''`.
