Hello,
I am facing issues when compiling a simulink model using GPU ACCELERATOR. I have downloaded simulink coder/matlab coder/GPU coder.
I am getting the following make error:
Making simulation target "Realtime_Catheter_Control_sfun", ... "D:\bin\win64\mex.exe" -R2018a -c -DMATLAB_MEX_FILE -I"E:\massyl_joystick\slprj\_sfprj\realtime_catheter_control\_self\sfun\src" -I"E:\massyl_joystick" -I"D:\extern\include" -I"D:\simulink\include" -I"D:\simulink\include\sf_runtime" -I"D:\stateflow\c\mex\include" -I"D:\rtw\c\src" -I"E:\massyl_joystick\slprj\_sfprj\Realtime_Catheter_Control\_self\sfun\src" CFLAGS="$CFLAGS -Xcompiler " -O2" " half_type.cpp Unknown MEX argument '-O2 '. gmake: *** [half_type.obj] Error -1
Unable to create mex function 'Realtime_Catheter_Control_sfun.mexw64' required for simulation.
I don't know whether the problem is in my C++ compiler or the make file, or the header files, knowing that i didn't specify any header file in the GPU acceleration tab.
I'm currently using MATLAB 2021, even though it shows above ( first line of the error) -R2018a which could be a version by default that does no longer exist.
My expected program should create 3D objects that belong to my simulation model.
I would really appreciate your helps if someone got to solve these errors.
Thank you in advance,

CFLAGS="$CFLAGS -Xcompiler " -O2" "
It looks to me as if CFLAGS was not created properly. It should have resulted in
CFLAGS="$CFLAGS -Xcompiler -O2"

Hi, Thank you for your answer. So the problem is just on how it created the flags? not the complier? If so, how am I supposed to correct it? Do i have to modify the generated codes ( "half_type.cpp" mainly?) I'm using the cuda enabled mex-function. Do I have to install a Cuda toolkit instead? Thank you

Unfortunately I do not have experience with that particular toolchain.

It's okay, Thank you.

Can you clarify what you meant by "compiling a simulink model using GPU ACCELERATOR" ? Which options have you selected to generate GPU Code ? Refer the following example on generating CUDA code from SIMULINK model - https://www.mathworks.com/help/gpucoder/ug/code-generation-from-simulink-models-by-using-gpu-coder.html
