Installing 32 bit CUDA libs on Vista 64

I see from this thread:

http://forums.nvidia.com/lofiversion/index.php?t52605.html

that there may be some problems with cross compilation. I’m on Vista 64 and am building a 32 bit app that includes CUDA using VS 2005. I get a bunch of linker errors, that start like this:

[codebox]1>gpuray.obj : error LNK2019: unresolved external symbol _cudaGetDeviceProperties@8 referenced in function “int __cdecl cutGetMaxGflopsDeviceId(void)” (?cutGetMaxGflopsDeviceId@@YAHXZ)

1>gpuray.obj : error LNK2019: unresolved external symbol _cudaGetDeviceCount@4 referenced in function “int __cdecl cutGetMaxGflopsDeviceId(void)” (?cutGetMaxGflopsDeviceId@@YAHXZ)

1>gpuray.obj : error LNK2019: unresolved external symbol _cudaGetErrorString@4 referenced in function “void __cdecl __cudaSafeCall(enum cudaError,char const *,int)” (?__cudaSafeCall@@YAXW4cudaError@@PBDH@Z)

which I think is because I have 64 bit CUDA libs installed. I can build 64 CUDA apps fine with this system.

Can I install the 32 bit libs on this machine to get it to work? If so, how can I do this as I am hestitant to download and install the Vista 32 bit driver, toolkit and SDK on this machine. Can I install just the SDK to pick up the 32 bit libs?

Thanks!

Now that I’ve been searching even more about this, I see there are a few other threads about setting this up. I guess I’ll experiment …

After mucking around with the libs/dlls and file structure, I have it working. Given that nVidia is giving you the option to cross-compile they really should straighten multi-target development installs out.
