“gpjmodify is not an internal and external command” this means you do not have gpjmodify in your PATH variable. Either add folder containing it to the path or call it explicitly with full path like “c:\GHS\bin\gpjmodify default.gpj -generate\_makefile” ---

Thank you so much for the reply, after giving “C:\GHS\bin\gpjmodify default.gpj -generate\_makefile” getting the same error, when I launch the IDE “Multi\_716”, utility-\>launch utility programs, I am able to see gstack,gfile,gwhat,gversion,gnm,gsize utility programs but not finding gpjmodify utility, is this one is the problem? how to enable the gpjmodify utility? ---

This question should be directed to Greenhills. Digi stopped supporting Greenhills compiler many years ago. ---

honestly, I am not sure GHS is still alive. I’d recommend switching to GNU compiler. You’d be able to use a much newer version of Netos this way. We stopped supporting GHS in Netos 7.4, which at this point is full of bugs and security vulnerabilities. ---

The gpjmodify utility is under the compiler directory. Use as below: C:\GHS\comp\_\gpjmodify default.gpj -generate\_makefile
