Note that DemoRunner and Projucer compile fine (no warnings).

Probably same advice! :grin:

Is there a way to get juce_recommended_warning_flags in Projucer (i mean instead of manually decipher the CMake files)?

5

There’s “Add Recommended Compiler Warning Flags” in each exporter’s configuration settings.

Oops… i did not noticed that. Thanks.

At the same time i get more than 2000 overzealous warnings now. I’ll keep mine. :grinning_face_with_smiling_eyes:
