Hi Richard/Gents  
I am trying to build and run the (WIN32-MingW) example under&nbsp; \FreeRTOS\Demo\WIN32-MingW&nbsp; 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?&nbsp; 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](http://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html)

Regards.

many thanks……
