"Failed to load the .dll" when using flex #3

Closed ulyssesdotcodes closed 5 years ago

The project compiles and links correctly, but whenever the code uses the flex library (for example NvFlexDeviceGetSuggestedOrdinal) TouchDesigner spits out the error "Failed to load .dll". When the flex library usage is commented out, the dll loads.

Minimum repo: edit the TouchDesigner CudaTOP sample to add flex to the project and these two lines to CudaTOP's initialization

    int g_device = -1;
    g_device = NvFlexDeviceGetSuggestedOrdinal();

This is with everything compiled for x64.

Sorry missed that, I think you need to add NvFlexDeviceRelease_x64.dll along the other dlls. Otherwise indeed you can comment out the lines that use NvFlexDevice* though creating the special cuda context makes the sim a little bit faster.
