Enable extra warnings windows?

General JUCE discussion
1

Is there any easy way to enable extra warning on Windows for only my application code and have the warnings disabled for the juce library code?

You can add a “Compiler Flag Scheme”:

then specify the warning flags in the Compiler Flags for "<scheme>" field of the exporter.

The only downside of this method is that the warnings will also be enabled for JUCE code that is included in your source files.

If you want to enable warnings in a more restricted way, you can use something like

#if defined(_MSC_VER)
#pragma warning(default:4700)
#endif

See https://docs.microsoft.com/en-us/cpp/preprocessor/warning for more details.

I ended up disabling 4242 with a pragma, maybe this could get done in main branch as well?
