[Gdal-dev] Re: OGR with Geos in Windows?

[Rodrigo Aceves]

Hi Frank,

I've done as you suggested and it compiled OK, but when it comes to link
there are a lot of warnings and errors. The errors are something like
"function already defined in geos.lib" and at the end it says "library
conflicts, use /NODEFULTLIB:library". The problem is with two libraries. But
when I use de NODEFAULT there are more erros. This time the errors say
"scanf not defined" or something like that.

Let me explain what I did: I created an empty project in VC .NET and added
all the files of GEOS and compiled, it worked after minor changes in the
code. So it produced a geos.lib file.

Then I use your suggestion and added geos.lib to the ADD_LIBS path. And put
the headers diretory inside the ogr directory. I defined HAVE_GEOS and ran
Nmake.

That's when I get all this errors.

Any idea?

Thanks in advance.
