Different Defines in Different Folders [message #720108]

I have a project that I'd like to use within CDT. One unfortunate thing is that it uses different defines in different folders, and so Eclipse can't show the right sections of code in #ifdef's. Is there some way to make Eclipse understand that different folders have different defines?

You must set up different build configurations. For each build config you can define source lcoations and symbol definitions.

You can set different defines in folder properties or even in file properties. Right-click on the folder -> Properties->C/C++ General->Paths and Symbols and select Symbols.

This mostly works. I find that when I open up the properties editor for a directory it doesn't always show the correct thing, but when I change the value and save it everything works. Thanks.

Is there a way that I can set these defines on directories from inside a plugin?

There are a few ways but perhaps the easiest to explain is http://wiki.eclipse.org/CDT/Developer/FAQ#How_do_I_contribute_Include_.26_Library_paths_to_a_project_configuration.3F

It seems I need a CExternalSettingProvider to do this, from package org.eclipse.cdt.core.settings.model.extension. This doesn't seem to be part of my installation, and I believe I have all CDT packages installed. Where can I find it?
