[cfe-dev] XCode + CLANG_ANALYZER_EXEC?

[Mathieu Baudet]

Hi,

Does anyone know a way to override the path to clang(analyzer) from
the configuration files of a XCode 5 project?

So far the only (unsatisfactory) solution I found is to modify the
global plugin file "Clang LLVM 1.0.xcspec" manually or using the tool
set-xcode-analyzer, then restart Xcode.

Surprisingly, the default value of CLANG_ANALYZER_EXEC in "Clang LLVM
1.0.xcspec" it not overridden by exporting an environment variable
before launching Xcode (from the shell). Yet in the same condition
setting the environment variable CLANG_ANALYZER_OTHER_FLAGS does work.
Deleting the default value for CLANG_ANALYZER_EXEC in the .xcspec file
then setting a global variable at launchtime works but then XCode will
crash on subsequent sessions when the global variable is not set.

Ideally I would like to set these variables in the .xcconfig file. I
tried but this does not appear to do anything. Is this supposed to
work? Should I create a custom compiler plugin?

Thanks!
