Version 2.14.0 of cppcheck generates errors relating to the
check level (e.g.):-
common/base64.c:0:0: information: Limiting analysis of branches. Use --check-level=exhaustive to analyze all branches. [normalCheckLevelMaxBranches]
This does not happen with the same sources (commit
f781962a55) under 2.13.0.
This PR disables the warnings above for 2.14.0, but also allows a '-f'
argument to be passed in to request an exhaustive test. This could be used
(for example) before a major release. An exhaustive test takes a *lot*
longer. The first run with a git runner was around an hour.
The --check-level=flag was only added for 2.11.0, and so this now needs
a version check.

# Script to run cppcheck
|
|
#
|
|
# Usage: /path/to/run_cppcheck.sh [-f] [ -v CPPCHECK_VER] [<extra_opts_and_dirs>]
|
|
#
|
|
# - If <extra_opts_and_dirs> is missing, '.' is assumed
|
|
# - If '-f' is specified, the exhaustive check level is used. This can take
|
|
# an hour or two.
|
|
# - If -v CPPCHECK_VER is specified, that version of cppcheck is run from
|
|
# ~/cppcheck.local (whether or not it's there!). Use install_cppcheck.sh
|
|
# to install a new version.
|
|
#
|
|
# Environment (all optional):-
|
|
#
|
|
# CPPCHECK : Override the default cppcheck command ('cppcheck').
|
|
# Ignored if -v is specified
|
|
# CPPCHECK_FLAGS : Override the default cppcheck flags
|
|
# CPPCHECK_QUICK : If non-zero, disables the exhaustive check level.
|
|
# Useful when developing
