Re: Fun with Squid2 and Clang

That's weird - I could have sworn it said that it was c / objective-c / c++.


Ah, well.

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 workfor

C++ programs.

And some seconds further digging gives

   http://clang.llvm.org/cxx_status.html

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?
