First you need to meet the system requirements:
SystemRequirements: GDAL library from
Since that has build instructions which say
GDAL can be built on Windows using MS VC++ 6.x and MS Visual Studio .NET
(C++) at the DOS command line.
you will first need to get a copy of DOS and those compilers. (I suspect
they mean the Windows command prompt, but they don't seem to know the
difference which is not confidence-inspiring. I also suspect they mean
`or' not `and'.) Then you will have to fathom out how to link against a
VC++ DLL which since this C++ is very unlikely to work with MinGW. So you
probably need to make the package's rgdal.dll under VC++ -- see
I have tried and failed to make GDAL with MinGW.

Do read README.packages and follow the advice at the top. You don't have
the (mis-attributed) tools in your path. But that is probably the least
of your potential problems.
