Unable to link, 64bit 7, unresolved external symbol unresolved external symbol _shrLog referenced in

Accelerated Computing CUDA CUDA Programming and Performance

I’ve installed 3.1 on windows 7, and VS 2008, together with the stable 1.0 release of nSight

All the samples I’ve tried building fail with linker errors like:
1>bandwidthTest.cu.obj : error LNK2019: unresolved external symbol _shrLog referenced in function _main
1>bandwidthTest.cu.obj : error LNK2019: unresolved external symbol _shrSetLogFileName referenced in function _main
It’s not always that specific message, but it’s sometimes something similar, depends on with sample.

Google reveals little about this unfortunately.

The issue seems to be related to my 64bit install, but I’ve yet to determine more details.

I am having the same issues… I can build on CUDA 3.0, Win XP x86, Visual C++ Express 2008 or 2010, but not when I move over to Windows 7 x86_64, CUDA 3.1, Visual C++ Express 2008 / 2010 or Visual Studio 2008 / 2010. I’ve tried adding the path to the 32 bit libraries, however, that doesn’t seem to resolve anything either…

ERROR:

1>main.obj : error LNK2001: unresolved external symbol _cudaEventCreate@4

1>main.obj : error LNK2001: unresolved external symbol _cudaEventElapsedTime@12

1>main.obj : error LNK2001: unresolved external symbol _cudaEventSynchronize@4

1>main.obj : error LNK2001: unresolved external symbol _cudaEventRecord@8

Anyone know what’s going on?

use 64 bit lib would help
