Hi There,

I have been trying to compile osgCompute and osgCuda and have been facing linking problems. I have provided links to all directories as far as I know. Please find the log below. Any help would be greatly appreciated.

your project (osgCuda) does not link to cudart.lib. This causes your problems. Actually the cmake script FindCuda.cmake (located in CMakeModules/cuda) should ensure that your nvcc is found. Once it is found the script sets libs and includes automatically. (I'm wondering that cmake has generated you a project while not finding the proper lib). You can also set the environment variables CUDA_BIN_PATH, CUDA_INC_PATH and CUDA_LIB_PATH to the correct folders of your system (this is actually done automatically during the cuda installation).

Please check the setting of your CUDA_RUNTIME_LIBRARY variable (in advanced view of cmake). This should fix your problem.



Best regards,
Mick

Hi Mick,

Thank you very much for your reply. I did check the settings for CUDA and they seem to be set correct.

Here are some screenshots of the cmake
http://rehmanrulz.googlepages.com/screenshot1.jpg
CUDA_RUNTIME_LIBRARY seems to be the set path.

I get a couple of warnings as well during cmake.

I'm working on a 64bit Vista machine. Any possibilities that this is causing issues?

Please do let me know and thanks again!

I have to admit that we didn't test our scripts on Vista 64 Bit.
Unfortunately we don't have a Vista 64 Bit machine ready for testing that's why it is a bit tricky for us to analyze the error at the moment.

Could you please help us to fix this problem? Did you try to compile OSG and osgCompute/osgCuda in 32 Bit mode? Does this work for you?

The cmake warnings sound very strange...

Thanks and best regards,
Mick

Hi Mick,

I can gladly help testing on a 64bit machine from my end.

OsgCuda seems to compile when I linked to the 32bit cudart.lib library. But I get a lot of errors when compiling the examples provided.

List of errors for osgTexDemo.

We are testing osgCompute/osgCuda on a 64Bit Windows 7 machine at the moment. We will update the scripts as soon as we have found a solution.
