Scan service and "This platform is not supported by Coverity" - xcode

Question

I'm trying to submit a scan under OS X. The procedure I am following works great under 32-bit and 64-bit Linux, and a similar procedure works great under Winows with nmake. On OS X cov-build is failing with:
$ CXXFLAGS="-DNDEBUG -g2 -O3" cov-build --dir cov-int make -j 2
Coverity Build Capture (64-bit) version 8.5.0.3 on Darwin 12.6.0 x86_64
Internal version numbers: db70178643 p-kent-push-26368.949
Platform info:
Sysname = Darwin
Release = 12.6.0
Machine = x86_64
[ERROR] This platform is not supported by Coverity.
[ERROR] See documentation for the list of supported platforms.
A different OS X machine produces the same error:
$ CXXFLAGS="-DNDEBUG -g2 -O3" cov-build --dir cov-int make -j 2
Coverity Build Capture (64-bit) version 8.5.0.3 on Darwin 13.4.0 x86_64
Internal version numbers: db70178643 p-kent-push-26368.949
Platform info:
Sysname = Darwin
Release = 13.4.0
Machine = x86_64
[ERROR] This platform is not supported by Coverity.
[ERROR] See documentation for the list of supported platforms.
I'm having trouble locating the documentation:
$ cov-build --help
Coverity Build Capture (64-bit) version 8.5.0.3 on Darwin 12.6.0 x86_64
Internal version numbers: db70178643 p-kent-push-26368.949
No help found for 'cov-build'
Coverity Data Sheet states OS X is supported, and a press release states OS X 10.8 is supported.
AIX
FreeBSD
HP-UX
Linux
Mac OS X
NetBSD
Solaris
Windows
Why am I receiving [ERROR] This platform is not supported by Coverity, and how do I fix it?

Answer 1

The issue is that Mac OSX 10.8 isn't supported in the Coverity release you're using. It's somewhat common for Apple to break compatibility with Coverity with OS releases, unfortunately.
You can export COVERITY_UNSUPPORTED=1. This will bypass the platform support check, however there's no guarantee things will work as expected. You do have reasonably good odds of success.

Answer 2

This builds on Flash Sheridan and Caleb's suggestions. The problem was less with the platform and more with the compiler. Xcode 5.0 and 5.1 produced the scan build failure:
CXXFLAGS="-DNDEBUG -g2 -O3" cov-build --dir cov-int make -j 2
...
cat cov-int/build-log.txt
...
"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../
lib/clang/5.0/include/stddef.h", line 29: error #109:
expression preceding parentheses of apparent call must have
(pointer-to-) function type
#if !defined(_PTRDIFF_T) || __has_feature(modules)
"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../
lib/clang/5.0/include/stddef.h", line 31: error #59:
function call is not allowed in a constant expression
#if !__has_feature(modules)
...
The second work-around depends on Flash Sheridan and Caleb's workaround. It adds "use a different compiler". Below, we use MacPorts Clang 3.7 to perform a scan build.
$ CXX=/opt/local/bin/clang++-mp-3.7 COVERITY_UNSUPPORTED=1 CXXFLAGS="-DNDEBUG -g3 -O2" cov-build --dir cov-int make -j 8

For anyone interested, we are a Free and Open Source Software project, and we take advantage of the Coverity Scan Service at no charge. However, the documentation is kind of light.
