# 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
