LLVM compiler settings, clarification needed
Are compiler settings set per project or once and for all?
For example, can one declare:
For all projects i create from this day forth, until told otherwise, treat all warnings as errors
If you're using Xcode*, just use shared/global xcconfig files. Definitions at the project and target levels have precedence if defined, so you can make exceptions and/or combine them in many ways.
Xcconfig Crash Course:
Then you just fill the xcconfig file with the build settings you want, like so:
ADDITIONAL_SDKS = ARCHS = x86_64 SDKROOT = macosx10.7 ONLY_ACTIVE_ARCH = NO SUPPORTED_PLATFORMS = macosx VALID_ARCHS = i386 ppc ppc64 ppc7400 ppc970 x86_64
- You can #include xcconfig files in xcconfig files (with some restrictions)
- You can drag+drop build settings from Xcode's build settings view to a text file.
So, if all you want is "Treat warnings as errors", your xcconfig would have this:
GCC_TREAT_WARNINGS_AS_ERRORS = YES
