Re: Fun with Squid2 and Clang
Hm. I'm trying 3.HEAD now, but it's giving me some trouble; analysis starts up fine, but when it gets to doing cf_gen_defines, it switches over to using g++ and doesn't switch back; see below. cf_gen didn't cause any problems for squid2; is there something new and weird in the build process here?

Re: Fun with Squid2 and Clang
Maybe that it's C++ while the others are C? Hmm.. from Clang homepage The Clang Static Analyzer consists of both a source code analysis framework and a standalone tool that finds bugs in C and Objective-C programs.. C++ is not C or Objective-C, so it's not too strange it doesn't work for C++ programs. And some seconds further digging gives http://clang.llvm.org/cxx_status.html Regards Henrik ons 2009-09-02 klockan 19:17 +1000 skrev Mark Nottingham: Hm.

Fun with Squid2 and Clang
Seeing the fun new tools in Snow Leopard's XCode, I dug a bit and ran Clang's static analyser http://clang-analyzer.llvm.org/ on squid2- HEAD; see http://www.mnot.net/test/squid-scan/ for results. If this is interesting/useful, I can do a quick run on squid3 as well; it's pretty easy. Cheers, -- Mark Nottingham m...@yahoo-inc.com
