gpucoder error: Cannot open include file: 'stdio.h': No such file or directory

I'm using VS 2017 community and Windows SDK 10

I'm trying to build a mex file using gpucoder, I'm getting this error

C:\Program Files\MATLAB\R2021b\extern\include\mex.h(38): fatal error C1083: Cannot open include file: 'stdio.h': No such file or directory

While tracing I found the error due to the line

cl /c /Zp8 /GR /W3 /EHs /nologo /MD /D_CRT_SECURE_NO_DEPRECATE /D_SCL_SECURE_NO_DEPRECATE /D_SECURE_SCL=0 /DMATLAB_MEX_FILE /DMATLAB_MEX_FILE /O2 /Oy- /DNDEBUG /fp:strict /source-charset:utf-8 /I "." /I "E:\Hatem\BarrierBox" /I ".\interface" /I "C:\Program Files\MATLAB\R2021b\extern\include" /I "." -DHAVE_LAPACK_CONFIG_H -DLAPACK_COMPLEX_STRUCTURE -DMW_HAVE_LAPACK_DECLS -DMW_CUDA_ARCH=350 -DMODEL=chol_call_mex -DMW_NEEDS_VERSION_H interface\_coder_chol_call_info.cpp /Fobuild\win64\_coder_chol_call_info.obj

I added

/I "C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\ucrt"

and I got this error:

C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\ucrt\corecrt.h(10): fatal error C1083: Cannot open include file: 'vcruntime.h': No such file or directory

I added

/I "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include"

and it works

Is there a better solution to automatically generate the command lines to use these include folders?

Thank you.

Hi Hatem Fayed,

I understand that you are attempting to generate a GPU MEX using GPU Coder, and you've encountered a 'Cannot open include file' error. To address this, you manually provided the include directory path, which resolved the issue.

Typically, there's no need to explicitly specify include directory paths. One possible reason for encountering this error is an incorrect configuration of the C/C++ compiler. To set the default C/C++ compiler that should be used by GPU coder, enter the below command and follow the instructions shown in the screen.

% to select c compiler
mex -setup c

% to select C++ compilelr
mex -setup cpp

After this you can use the GPU Coder through command prompt as follows,

codegen -config coder.gpuConfig('mex') -args {Arg1,Arg2} function_name

For more information on Compiler setup, refer the following MATLAB documentation,

Hope this is helpful.
