Hi there. Again, I’m new to this whole rtos concepts. I’m using MPLAB v8.56, trying to build the rtosdemo for the PIC18F (18F452 to be exact.)

The following error is found:

Debug build of project `C:FreeRTOSDemoPIC18_MPLABrtosdemo1.mcp’ started.
Preprocessor symbol `__DEBUG’ is defined.

Clean: Deleting intermediary and output files.
Clean: Deleted file “C:FreeRTOSDemoPIC18_MPLABrtosdemo1.mcs”.
Clean: Done.

Couldn’t locate build tool.  Check tool locations.

Debug build of project `C:FreeRTOSDemoPIC18_MPLABrtosdemo1.mcp’ failed.
Preprocessor symbol `__DEBUG’ is defined.

BUILD FAILED

What am I doing wrong? What must I do to rectify this?
Appreciate any answer thanks

That sounds like you don’t have MPLAB installed right. Did you install the C compiler too? (It isn’t part of the base MPLAB download). The other possibility is that I think MPLAB stores tool location in the individual project, so if you are grabbing a sample project, they may need to be updated if your install didn’t put them in the standard places.

Thank you, Richard I finally got it working. I downloaded the C-compiler for 18F, installed it and it works. Feeling a bit stupid, but anyhow, that’s how one learn.
