That problem can occur if you have a space in a directory name of a file that is being referred to as part of compilation.

[Bob Snyder]

Thanks for the feedback, but I checked all of my files/folders and there are no spaces

[Walter Roberson]

Apparently it can also occur if there is a colon in any of the directory names or file names referred to.

[Bob Snyder]

Such as in C:\ti\..... ? Assuming the : after the 'C' is OK then I don't have any other colons.

[Walter Roberson]

The : after the C should be okay.

On Windows, getting a : in a file name other than as a drive or device specification is not easy.

Can you post the content of C:\Users\bsnyder\MathWorks\GPIOtest_ert_rtw\GPIOtest.mk ?
