[postgis-devel] mingw autotools

Paul,
Yes that sounds familiar.  Haven't been able to build the GEOS 3.2+ with the
newer MingW (I could build 3.1 with the newer), so I had to scrap my newer
install and revert when started working on 1.5.

 Even gdal which WKT Raster relies on technically doesn't support MingW,
though it works with some hacking. 

Anyway.  For 2.0 I want a clean start and go VS/VS Express all the way. 

Thanks,
Regina

It got more confusing, unfortunately. I had an older VM configured exactly
to the old wiki page and the autotools there spit out a usable configure. So
the problem (maybe?) is with moving up to the latest minor version of
MingGW? So I don't know what the answer is except that building with MinGW
is impossibly confusing. If VCC can offer a saner build situation it might
be worth the time spent to just suck it up and go to a pure VCC build. Proj
and GEOS already build in VCC as does pgsql so it's just postgis to do...
