Projucer Preprocessor definitions config-wise

Hello,
I’m having a big difficulty getting specific values of preprocessor definitions, depending on the configuration chosen.
I’ve seen that XCode recognises the value 0 for POPO if I write POPO=0 in the XCode exporter section, under “Extra Preprocessor definitions”.
But if I additionally write POPO=1 in the Release config for XCode under “Preprocessor definitions”, and go for the Release scheme in XCode, POPO is still set to 0.
Then if I try to set it directly from the Release config, without defining POPO in the general exporter section, I’ve got POPO not defined once in XCode.

You can define them once in the global settings

I think they are overridden by the config specific settings you use.

Hope this clears things up.

The point I was making is that precisely, they are not overriden by the config specific settings. (“POPO is still set to 0”).

Dumb question: did you re-generate the build files in Projucer before opening them again in XCode?
