GPU Accelerator Make error

Hello,

我编译仿真软件模型时所面临的问题金宝appusing 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,
