I am attempting to compile a program using CUDA, and am getting the following error in response
C:\Program Files\MATLAB\R2024a\sys\cuda\win64\cuda\include\crt/host_config.h(164): fatal error C1189:
#error: -- unsupported Microsoft Visual Studio version! Only the versions between 2017 and 2022
(inclusive) are supported! The nvcc flag '-allow-unsupported-compiler' can be used to override this
version check; however, using an unsupported host compiler may cause compilation failure or incorrect run
time execution. Use at your own risk.
I looked and it seems the problem is caused by a small glitch in a recent update of visual studio that shouldnt have any effect on the compiler. How do I add the flag to override the version check? My current code is as follows
mex -setup:'C:\Program Files\MATLAB\R2024a\bin\win64\mexopts\msvcpp2022.xml' C++

I am having the same difficulty. How did you verify this?

Hi Aiden,
I encountered the same problem, and solved it by setting environmental variable "NVCC_APPEND_FLAGS".
To do this, you can try:
setenv("NVCC_APPEND_FLAGS", '-allow-unsupported-compiler')
mexcuda -v mexGPUExample.cu
Hope it helps!

Hi Aidan,
To address the issue, you can ensure that the compiler and its version are supported with the product. You can find the list of supported and compatible compilers at the following link:-
The tables on this page outline the compilers that are supported by various MathWorks products.
For configuring parameters for CUDA code generation, you can use "coder.gpuConfig". This allows setting additional flags for the GPU compiler, including the NVCC flag. You can find more information on how to set these properties in the below provided MATLAB documentation link:-
