I'm trying to debug some textures and FBO's with Nvidia Nsight 4.6 VS Edition. But when I select either "Start CUDA debugging" or "Start graphics debugging" I get an error.

"The program can't start because glew32.dll is missing for your computer. Try reinstalling theprogram to fix this problem"

The application runs just fine when I'm not using Nsight. What might be my problem?

My system; Windows 7 x64 bit. Nsight 4.6 x64 bit. GTX 580 with lastest drivers. OpenGL version 3.3. Building a Win32 application. (Tried to change the build target to x64 but that just resulted in a bunch of linking errors for glfw and glew)

Okey I found the problem. I had placed my glew32.dll file in a separate folder and set the environmental path to that location. e.g: Properties > Configuration Properties > Debugging > Environment = PATH=$(ProjectDir)..\dependencies\bin;%PATH%

Apparently Nsight didn't realize this and thus couldn't find the dll.

  • \$\begingroup\$ This was some time ago, so hopefully my memory doesn't fail me here... But you have to place the gew32.dll in the same folder as your binaries. Please reply to this comment if this fixes your issue. \$\endgroup\$

    \$\begingroup\$ In the end, because I didn't want to move libs (they are a separate project) and since it doesn't look like there is a way to do it in Visual Studio or Nsight, I made a .bat file to set the PATH to my DLLs and then start the program (checked that "application is a launcher" box in Nsight options). \$\endgroup\$
