Hi I have an XCode project which is ARCd but uses some 3rd party (AFNetworking)
classes which are not ARCd. I have specified the -fno-objc-arc flag against
these files in my Xcode project however when I run scan-build I get a number of
errors such as:-

error: 'autorelease' is unavailable: not available in automatic reference
counting mode

I can see that scan-build is using -fobjc-arc when compiling / checking these
classes which is incorrect.

Please could someone advise how I can get scan-build to pick up the correct

FYI I am using checker-267 version downloaded from

Many thanks
