After troubleshooting getting codegen to work in MATLAB, I've got some errors to report and solutions for people struggling like I was. If these cannot be fixed, it would be helpful to have some messages in the docs about these specifics.
In MATLAB 2021a the supported minGW compiler (installed in the MATLAB gui as a support package) fails with error "Error configuring CMAKE environment" because "CMAKE_MAKE_PROGRAM" is not set. The osqp docs currently suggest installing this compiler through a url to matlab's supported compilers, so this error is bound to happen for others.
Add this line to your matlab code:
setenv('MW_MINGW64_LOC', 'C:\TDM-GCC-64');
Add this line to your matlab code:
setenv('PATH', [getenv('PATH') ';C:\TDM-GCC-64\bin']);
where C:\TDM-GCC-64 is replaced in 2 and 3 with the location of your TDM-GCC installation.
When installing osqp from the MATLAB terminal using the commands given in the osqp docs:
>>websave('install_osqp.m', 'https://dl.bintray.com/bstellato/generic/OSQP/0.6.2/install_osqp.m');>>install_osqp
the installation is saved to whatever directory is matlab's current working directory. If this path is too long, codegen will fail at some point due to mex.
