This is very likely an issue with your setup (perhaps your nmake.local, or missing MSVC_VER=1600) . GDAL builds fine with MSVC 2010. See ​http://vbkto.dyndns.org/sdk/ that has SDKs ready to download and compile. You might compare with that what's wrong with your setup.

Closing. Reopen if you have more precise elements

ok. I've been building gdal for 4 years with VS2005. I guess maybe VS2010 is differant. All I did was get latest and change the 64bit flag to yes and rebuild all.

If I open the vs2010 command line (64bit) and build(nmake /f makefile.vc), intead of using the provided vs2010 solution, I get an error that may help figure out whats going with the gdal build system. I'm kinda wondering if a flag somewhere is getting missed in a file, so half is building as x86 and the other half as 64bit?

MSVCRT.lib(ti_inst.obj) : fatal error LNK1112: module machine type 'x64' conflic ts with target machine type 'X86' NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 10.0 \VC\BIN\amd64\link.EXE"' : return code '0x458' Stop.

I figured it out.. anyone that builds both x86 and 64 bit using vs2010 will run into this. It seems running "clean" from the vs2010 solution/IDE isn't working/cleaning everything. Once I did a "nmake /f makefile.vc clean" and then a nmake /f makefile.vc I was able to build and link! I'm using vs2010 ultimate edition if that matters...

[vindoctor]

Incase its not clear, since the clean was not really cleaning all the x86 objects, it was doing a mix/match between the 32 and 64bit objects... hence all sorts of link errors.

Seems like Even was correct, re-closing. Reopen if I am wrong.

Just to note for anyone else having the issue.. I'll try to look more into this when I can.. but in the meantime, a clean build is not really doing a "clean" so make sure you manually delete your files if you do a 32 bit build before your 64bit build.
