You are correct, I am using that bat file to configure the VC environment. I did a search and found the 32.bat file so I will try and use that.

When I try to build gdal for x64 using the make file from the Win64 command prompt and WIN64 = YES in the nmake.opt file everything compiles fine. (using gdal 181 by the way). If I try to compile it for x86 using the Win86 command prompt and comment out WIN64 in nmake.opt file I always get a linker error where the compiler complains that the target machine doesn’t match.
