[geos-devel] Re: Where did distancePointLine go?

[Stuart C Sides]

Mark,

I am compiling on Linux x86_64 with only the --prefix option for 
configure. I have tested 3.0.0rc4 and several SVN versions. To make sure I 
had the latest I downloaded the SVN version again on Oct 8th. I continue 
to get the following:

If I manually copy CGAlgorithms.h and GeometrySnapper.h from 
"source/headers/..." to their respective include areas everything works 
fine including the ld and execution. It seems odd that the object modules 
would be in the library but these two include files are not moved during 
the "make install".

Thanks

Hi Stuart,

Are you using GEOS 3.0.0rc4 compiled as a DLL under Win32? There was a
fix a while back for MingW DLLs that was causing functions not to be
exported which has been fixed in the SVN repository.


ATB,

Mark.
