To be honest, I'm not sure if there is a way around this problem, except upgrading the GCC used by the build bot from 4.2 to 4.4 (the minimum version mentioned by cppcheck), which is probably easier said then done.

The `gcc-4.2` used by the buildbot is the system compiler, and Apple stopped upgrading its system gcc at version 4.2, so upgrading the system gcc to 4.4 is out of the question. Instead, the port should use `compiler.blacklist` (and/or possibly also `compiler.whitelist` and/or `compiler.fallback`) to only allow MacPorts to use compilers that work. See the UsingTheRightCompiler wiki page for more info on how to do this. -- Ticket URL: <https://trac.macports.org/ticket/43757#comment:3> MacPorts <http://www.macports.org/> Ports system for OS X

...

Edit: turns out that that wiki page fails to mention those keywords specifically, but it still contains the same general idea that is necessary here.

Will the attached diff do the trick? I don't think I'm using these keywords in the right way, but I can't find proper documentation.

I would use `-append` with those keywords, and especially with `compiler.fallback`, because MacPorts already comes with a default fallback list of compilers, and without using `-append`, you end up overwriting it. Not exactly sure where the default fallback list is stored/documented though... -- Ticket URL: <https://trac.macports.org/ticket/43757#comment:5> MacPorts <http://www.macports.org/> Ports system for OS X

There is no compiler called "`macports-clang`". There are multiple versions of MacPorts clang, e.g. "`macports-clang-3.4`", etc. -- Ticket URL: <https://trac.macports.org/ticket/43757#comment:7> MacPorts <http://www.macports.org/> Ports system for OS X

If the code really uses C++11 the C++ runtime on SL will also be too old for this code and the use of `libc++` would be required. So far, projects using C++11 are only supported on Mavericks and beyond in MacPorts. It's worth a shot anyway, though. -- Ticket URL: <https://trac.macports.org/ticket/43757#comment:9> MacPorts <http://www.macports.org/> Ports system for OS X
