Cppstyle calls clang-format with `-fallback-style` command line parameter

[bitswype]

The -fallback-style command line parameter is not available in all versions of clang-format and older versions of clang-format will fail to run if the command line option is passed.

I am forced to use an older development environment which only supports clang-format v3.4. This version of clang-format does not support the fallback style option, so cppstyle fails.

Perhaps an option to enable / disable this feature?

Error in CppStyle Output Tab

clang-format return error (1).
clang-format: Unknown command line argument '-fallback-style=Google'.  Try: '/usr/bin/clang-format -help'

Need a config for using older clang-format versions.

Hi, I've been hit by this bug as well, with my clang-format v5! Unfortunately I cannot use a different version, so please fix it!

Thanks @tonybeckett for the workaround... I will try that

Actually I realized that the problem I hit was due to using the system-installed clang-format instead of the one I wanted to use that is: /opt/rh/llvm-toolset-7/root/usr/bin/clang-format (from Centos7 software collections)
