How to solve 'Make command returned an error of 2'

Hey everyone,

When generating code for my Simulink model I receive the following error:

How can I generally investigate problems like these? As far as I see there are no clear statements why the make command failes. The only thing which looks a little bit strange is the path to gcc 'C:\Tools\MINGW_63\mingw64\bin/gcc' where a slash is used at the end while the rest is written with backslashes. Anyhow the environment variables should be fine. Also I checked that I don't have any whitespaces in any installation paths which could cause problems.

Did anyone manage to solve this error?

Hey Marcel,

I have faced a similar issue and there was no whitespace in my folder path as well.

What worked for me was moving the SLX files to a different folder location. This issue could have been due to the length of the folder path. Once I shortened the path, the problem was resolved.

Hopefully it might resolve your issue as well.
