[geos-devel] Geos 3 build issues on Windows

[Mateusz Łoskot]

Hi Charlie,

By the way, there is a Bug Tracker for GEOS that is a better place to
report bugs because then it will be guaranteed to
not to forgot about them ;-)

Are you sure those files do not include <algorithm> in latest CVS?
I did update (cvs update -P -d) my sandbox today and GEOS compiles well.
Here you can see that those files include (revision nr visible):

Yes. You have to remove those files from your project. Those files have
been left for some archive reason but should not be compiled.

You're right. Those files are empty and look like this:

namespace geos {
namespace geom { // geos.geom
namespace util { // geos.geom.util

} // namespace geos.geom.util
} // namespace geos.geom
} // namespace geos

strk:
Will those files be used for any purpose?

I have no idea :-(
May be those empty files for which VC++ gives warnings cause those errors?
