Hi Richard/Gents
I am trying to build and run the (WIN32-MingW) example under \FreeRTOS\Demo\WIN32-MingW using eclipse
I have set all the paths and have manualy copied the file portmacro.h in the project directory
when I build it recognized all the included header files but gives me all the below errors

It is just not finding (and therefore not building) the source files that, by default, are outside of the project directory.

Did you run the file FreeRTOS\Demo\WIN32-MingW\CreateProjectDirectoryStructure.bat before doing anything else? You should need to manually copy any files after the batch file has been run.

Read the "Preparing the Eclipse project" section of the following page:
http://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html

Regards.

cheers Richard

the batch file was the key, I ran that and re-imported the project again and its fine
many thanks......
