BTW the fact that Eclipse shows the macro expanding as 0 (which is seen also as the code itself is grayed out) may be an artifact due to indexing problems. To check you may rebuild th eindex, or go in th efile where the #if shows the value as 0 and
- add a syntax error in the conditionnaly compiled zone to check if it is compiled or not
- search which “main.h” file Eclipse think you are including by double clicking on “main.h” in the file outline (right column in your workspace): this will open the main.h file and you can check if your macro is defined as 1 or 0 (you can get the full pathname by hovering on the editor tab title).
Hope this helps
