[Qgis-developer] Compiling against geos-3.0.0rc4

[Mike Leahy]

Hello list,

I know that GEOS 3.x is not officially supported yet, but I've been able
to compile the released qgis 0.8 against geos-3.0.0rc3 without any
trouble - the patch that was posted in December, or something similar,
must have been applied before it was released.  I just tried compiling
against rc4 of GEOS, and produces some new problems.  The first error
(below) seems to be an issue with the linker.  After getting that error,
if I make clean then make again, I get a different error (also below).
Since the problem only happens with rc4 of GEOS and not rc3, I checked
with the geos-devel mailing list first, but so far no answers seem to be
jumping out.  Can anyone make sense of what's going on, or offer some
ideas that I could try?

Regards,
Mike

And here's what I get if I make clean, then try again (starting from a
fresh source instead will return me to the error above):
