Hi Wreckor,

As you have already noted, the first thing you need to change is the
exports in your test.def file, prefixing an underscore to TestFunc,
ie:

        LIBRARY test.dll
        EXPORTS
                _TestFunc

This takes care of the second error message.

Well without the -shared option the relocations are discarded, so the
linker is operating correctly.  (This is because in a non-shared
executable, all of the relocations should have been resolved, so there
is no need for the relocation table).

The real problem however is a bug in the linker.  Try applying the
patch below and then rerunning LD, but this time, include the -shared
command line option.

If this fixes your problem, please let me know so that the patch can
be applied to the sources.

Cheers
