How can I find geos_c.lib and libtiff_i.lib?

Hi everybody,
When I try to build MapWinGIS, I find that I need geos_c.lib and libtiff_i.lib, I don’t know where can I download them or how can I build these two LIBs, anybody can help me ?

Hello @chris , and welcome.

Have you reviewed the tutorial video for compiling the OCX? I know those libraries are distributed with the GDAL libraries; you should not have to build them.
