Re: [geos-devel] Building GEOS with GDAL

I did the change you mentioned but it does not work. Still gives the same warnings.

It gives these warnings while compiling ogrgeometryfactory.cpp, ogrpolygon.cpp and ogrgeometry.cpp. Here is the compile command

cl /nologo /MD /EHsc /Ox /DHAVE_GEOS=1 -I..\port -I..\ogr -I..\gcore -I..\alg -I\inc -I"D:\Software\VStudio\VC98\ATL\Include" -DWIN32 -I. -Iogrsf_frmts -I..\frmts\gtiff\libgeotiff -IC:/GEOS/trunk/capi -DHAVE_GEOS=1 /c ogrgeometry.cpp

Are all the flags and options correct?

And these are the errors i get at the end when it tries to link:

Any clue?

mmm... maybe the type specifier is just placed in the wrong
way:

133: extern GEOSGeometry* GEOS_DLL GEOSGeomFromWKT(const char *wkt);
134: extern char GEOS_DLL *GEOSGeomToWKT(const GEOSGeometry* g);

Since you don't get a warning on 134 I suppose it should be:

134: extern char * GEOS_DLL GEOSGeomToWKT(const GEOSGeometry* g);

Can you try ?
