MinGW overrides other toolchains defined in System target file with Embedded Coder

Hi,
I am currently working on a dsPIC project (Microchip) and am using the Microchip dsPIC Microcontrollers Support from Embedded Coder blockset (https://fr.mathworks.com/hardware-support/microchip-dspic.html) to generate code for my target.
I have also installed the MinGW-w64 plugin (<http://fr.mathworks.com/matlabcentral/fileexchange/52848-matlab-support-for-mingw-w64-c-c++-compiler>) that I used for other projects.
My Matlab version is R2015b.
But whenever I want to build a model for my specific target, no matter what, the building process will use the MinGW toolchain even if the correct "System target file" is selected in the "Code Generation" menu of the model parameters. And this System target file is working fine as soon as I remove the MinGW compiler from Matlab...
Here are the build outputs with the exact same model and the exact same parameters, with MinGW installed and uninstalled:

Now you would tell me that I just need to remove the MinGW compiler but I need it in order to perform PIL simulation, as it needs to compile host-side and target-side parts of my model.
If you have any suggestion on what is going on when the MinGW compiler is enabled...
Thank you.

Please refer to the following documentation links - https://www.mathworks.com/help/releases/R2017a/rtw/ug/program-builds.html#btz8pmx https://www.mathworks.com/help/releases/R2017a/rtw/ref/toolchain.html
I believe that the Toolchain setting currently set is 'Automatically locate an installed toolchain' for your code generation parameters, which selects MinGW by default. Consider selecting the Toolchain manually based on the target and compiler settings.

Hi, I can affirm that this problem only affects MinGW compiler as all is working correctly with the same settings with Microsoft SDK 7.1 compiler.
Or if you use MinGW 4.9.2 with Matlab R2017a, it also works ( Microchip forum thread )
Thanks

Hi Lovers,
i am working on a bachelor thesis with dspic33, i get almost same error. after marking a programm to my target, i am greeted with this message every time i want to make build, i ask you for a hint. In any case thank you.
