Fails at linking step: PIC24 demo example

Posted by Felix Hirzel on November 19, 2012
I am trying to start a new development project using a PIC24 and FreeRTOS in MPLAB-X. Having fallen foul of the include path issue in MPLAB-X, I thought this was going to be easier. But, no such luck.

The PIC24 demo imports fine into MPLAB-X and compiles without errors. However, I want to place my project in my usual project directory, so attempted to transfer the project over. MPLAB-X is less then helpful in this, it seems.

So, started from a clean project and added the files from inside MPLAB-X, duplicated all the compiler and linker setting. Compiles without errors, but clearly something is missing. At the link step, I get the following list of errors:

What am I missing? I'm stumped despite a good amount of effort to try to solve this.

Looks like you are missing FreeRTOS/Source/list.c in your project.
