I'm trying to compile a cuda test program on Windows 7 via Command Prompt, I'm this command:
nvcc test.cu
But all I get is this error:
nvcc fatal : Cannot find compiler 'cl.exe' in PATH
What may be causing this error?

Solve this problem by adding this options to nvcc
for example my compiler is VS2012. and cl.exe is in this dir
I see that this is an old question but I recently got this error on my Visual Studio 2012 when I tried to build my CUDA project. Apparently I had changed my CUDA project to the Nov 2012 pack, changing it back to the v110 that it usually is by default fixed this error.
In Visual Studio, left click on the CUDA project, ->properties->Configuration Properties-> General -> Platform toolset, and choose: Visual Studio 2012 (v110).
I could probably get it to work with the Nov 2012 pack, but the CUDA code does not use any of the additional functions of that pack, so it is not necessary. (That pack contains the variadic templates for C++11.)
You will need to add the folder containing the "cl.exe" file to your path environment variable. For example:
Edit: Ok, go to My Computer -> Properties -> Advanced System Settings -> Environment Variables. Here look for "PATH" in the list, and add the path above (or whatever is the location of your cl.exe).
cl.exeis Microsoft's C/C++ compiler. So the problem is that you don't have that installed where the command line can find it.For new Visual Studio
cl.exeis present in path =>C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.23.28105\bin\Hostx64\x64x64 is for 64bit
x86 is for 32bit
nvcc is only a front end for the CUDA specific part of the program. It must invoke a full compiler to finish the job. In this case it cannot find the Visual Studio compiler 'cl.exe'
Check paths, nvcc documentation etc.
