Codegen('mex') does not support custom toolchains, as noted in the documentation at the following link:
Compiler settings are inherited from the "mex -setup" command.
Instead, you can use the Post-Code-generation command to pass a custom Build Information Object to the "codegen" command.
For example, you could add a link flag with the following function:
function setbuildargs(buildInfo)
linkFlags = {'-lpthread'};
buildInfo.addLinkFlags(linkFlags);
cfg = coder.config('mex');
end
That function can then be used to pass the build information object via the PostCodeGenCommand:
>> cfg.PostCodeGenCommand = 'setbuildargs(buildInfo)';
More information and further examples can be found in the documentation at the following link:
