Compiling CUDA files with mexcuda - why wont Matlab accept my compiler?!

30 views (last 30 days)
Im trying to compile CUDA files into mex.
Matlab ships with an example CUDA file located in matlabfolder\toolbox\distcomp\gpu\extern\src\mex, but when I try to compile it by typing:
I get:
"Error using mex
No supported compiler or SDK was found"
Im using the Microsoft Visual C++ 2015 Professional (C) compiler for both C and C++ but Ive also tried the MinGW64 Compiler and the Windows SDK 7.1 which all gives me the same error.
Im using the CUDA toolkit 8, and in Visual studio I can compile .cu files so I obviously have a supported compiler. How do I make Matlab realize that and allow me to compile .cu files?

Hello Petter,
CUDA 8.0 was only released last week! mexcuda doesn't yet support it, and consequently does not yet support Visual Studio 2015, which is supported by CUDA 8.0 but not CUDA 7.5.

Like I said, mexcuda does not support Visual Studio 2015 because CUDA 7.5 doesn't support it. You need to use VS 2012 or 2013. mexcuda can only support the host compilers that the CUDA compiler supports.

I am using VS2010 and having the same problem. I don't think an earlier version of VS is the correct fix.

This is how to compile (mexcuda) with Visual Studio 2015 and Cuda 8.0 :
  1. Go to: "\toolbox\distcomp\gpu\extern\src\mex\win64"
  2. Copy files and rename 2013 to 2015: { "nvcc_msvcpp2013.xml" , "nvcc_msvcpp2013_dynamic.xml"}
  3. Replace inside those files "7.5" to "8.0" and "12" to "14".
  4. Done.

Actually when I tried your solution, an error came up: It says that the file ucrt.lib was missing. I searched the internet but could not find a solution, so I had no choice but to search for the file (in Program Files), then copy it to the Matlab's working directory. Only then did it work. But thanks anyway

Dang, is the name of file exactly ucrt.lib? I cannot find it in the program files.Thanks!
