[cfe-dev] scan-build throws error

[Artem Dergachev via cfe-dev]

This is a fairly normal compiler error and you should investigate it as 
such.

It might be caused by clang being passed incorrect flags from 
scan-build. It may also be caused by clang you're using for analysis 
being too old.

Does the project build fine without scan-build? I.e., just "xcodebuild ...".

What's the first reported error?

Also note that xcodebuild prints all compile commands to standard 
output. This means that you can easily investigate this compile error in 
isolation from scan-build.
