Does any one have any tips on how to debug errors due to slbuild? This occurs as I execute slbuild on a simulink model.

Hi Victor,
Usually, this error arises when the path is too long or contains whitespaces. The error may resolve when the path length has lesser than or equal to 260 characters (including drive letter and colon). Apart from these there seems to have occurred certain syntax errors that might have resulted in this issue.
Enabling “Generate Code only” or “Create Code Generation Report” options may act as a possible workaround.
Hope this helps.
