comment:1 Changed 10 years ago by xythobuz@…

It seems as if cppcheck requires a C++11 compiler since version 1.65 (http://sourceforge.net/p/cppcheck/news/2014/05/cppcheck-165/)

These features are used throughout the code. I was able to compile it without the "-std=c++0x" option using Clang, but a lot of warnings were produced.

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.

Should I somehow tell the buildbot not to build cppcheck for Snow Leopard?

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.
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.

Replying to xythobuz@…:

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...

Edit: found the default fallback list (from larryv in comment:ticket:44129:7 for reference), it can be found in the sources: tags/release_2_3_1/base/src/port1.0/portconfigure.tcl#L426

(updated the UsingTheRightCompiler wiki page with this link as well)

I have added the changes to the updated cppcheck 1.66 portfile in #44537, so this ticket can be closed.

comment:7 Changed 10 years ago by ryandesign (Ryan Carsten Schmidt)

In #44537 your attachment adds these lines:

compiler.blacklist-append   gcc* 
compiler.fallback-append    macports-clang

Blacklisting just "gcc*" will not blacklist any MacPorts gcc compilers, only those provided by Xcode, nor will it blacklist Xcode's or MacPorts' llvm-gcc, so think about what you really want there.

There is no compiler called "macports-clang". There are multiple versions of MacPorts clang, e.g. "macports-clang-3.4", etc.

comment:8 Changed 10 years ago by xythobuz@…

Okay, that makes sense. Will this work?

comment:9 Changed 10 years ago by neverpanic (Clemens Lang)

In r123101. 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.

OK, the results from the SL buildbot are in, and unfortunately this doesn't solve the problem yet. That's because the system clang shipped with Xcode on SL was too old to compile C++ code and always used llvm-gcc to do that:

See https://lists.macosforge.org/pipermail/macports-dev/2014-July/027365.html for an explanation of the problem. The fix is to add

PortGroup compiler_blacklist_versions 1.0

and to add

{clang < 137}

to the blacklist. OK to commit?
