GPU Coder: compilation error
20 ビュー (過去 30 日間)
I am trying to create a MEX function from the following simple function:
function G = ft2(g, delta)
% - g: gpuArray, double, complex, size: N x N
% - delta: double, size: 1 x 1
G = fftshift(fft2(fftshift(g))) * delta^2;
Although the MEX generation was successful when I specify the input g as a double array (non-gpuArray), it was not successful when I specify it as a double gpuArray. The build was successful but the compilation seems to have failed. The buildLog is like below:
C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30133\include\vcruntime.h(197): error #256: invalid redeclaration of type name "size_t"

Error limit reached.
100 errors detected in the compilation of "C:/Users/Daigo/AppData/Local/Temp/tmpxft_00002b68_00000000-10_ft2_initialize.cpp1.ii".
ninja: build stopped: subcommand failed.
There are more than 100 error messages. It seems like they have something to do with C complier and CUDA toolkit. I cannot imagine how much effort I will need to fix all the issues in the log. Does anyone have advice on the use of GPU Coder?

Please go through the installation and configuration deatils for GPU coder.
Prerequisites for GPU coder: Installing Prerequisite Products - MATLAB & Simulink (mathworks.com)
Setting up prerequisites: Setting Up the Prerequisite Products - MATLAB & Simulink (mathworks.com)
GPU environment check and setup app: The GPU Environment Check and Setup App - MATLAB & Simulink (mathworks.com)
After the above prerequisites, you can follow the example in documentation for code generation using GPU coder app.
Hope it helps!
