Code Generation Report prevents Mex generation

Hello everyone,

I have an issue with Matlab Coder. I can't generate a Mex file when a generation report is produced. For example with the testCodegen function below :

function y = testCodegen(x)
y = x + 2;
end

I have no error when building a Mex function without generating a report :

codegen -args {1} testCodegen

However, the following error arrive when a report is produced :

codegen -report -args {1} testCodegen

Compilation failed.
Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To
construct matrices, use brackets instead of parentheses.
Use help codegen for more information on using this command.
Error using codegen

The situation is the same when using the Coder App. This is really bothering me because I can't locate errors while building more complex Mex files! I didn't get this error a few weeks ago, I can't figure out where it comes from.

Does anyone has an idea?

This sounds like an installation problem. I suggest getting in touch with MathWorks Techincal Support: https://www.mathworks.com/support/contact_us.html to help diagnose the issue.

As a start I'd try:

restoredefaultpath
rehash toolboxcache

and then try codegen again. Beyond that, definitely suggest Technical Support.
