Failed to load custom code simulation

[xeeman]

Dear Deng,
I have tried the Quadcopte example, but the simulink file at the last step didnt run.
I t gives me this error:

Failed to load custom code simulation
library:D:\Users\sanim\Documents\MATLAB\MPC\ParNMPC\Quadrotor\slprj_slcc\oSDpra6UYTzTcubJVwU2TH\oSDpra6UYTzTcubJVwU2TH_cclib.dll
Component:Simulink | Category:Model error

Hi xeeman,

It seems some users have encountered the same problem, but currently, I don't know where the problem is.
Could u delete the slprj_slcc folder and try it again? Or "clear mex" might help.

Hello Haoyang:

I met the same question. It seems when run Simulink, the floder slprj/slcc would be created automatically. Then the same error happened. But now I dont know the reason. Have you figured it out? Thank you.

Hi. I solved the issue by disabling the import custom code flag in simulation configurations

1、type '' mex -setup'' command in matlab commandline
2、select ''Microsoft Visual C++'' instead of '' MinGW64 Compiler (C)''

note: i installed matlab2021a 、 visual studio 2019 and mingw6.3
