Prevent the BUILD module from shell-executing multiple processes to determine the avr-size flags to speed up the build, unless the size rule is invoked. Add warnings and set warnings as errors to the SingleUSBModeTest build test makefile.

# LUFA CPPCheck Buildsystem Makefile Module.
|
|
# -----------------------------------------------------------------------------
|
|
# DESCRIPTION:
|
|
# Provides a set of targets to scan a project with the free "cppcheck" static
|
|
# analysis tool, to check for code errors at runtime (see http://cppcheck.sourceforge.net).
|
|
# -----------------------------------------------------------------------------
|
|
# TARGETS:
|
|
#
|
|
# cppcheck - Scan the project with CPPCheck
|
|
# cppcheck-config - Use CPPCheck to look for missing include files
|
|
#
|
|
# MANDATORY PARAMETERS:
|
|
#
|
|
# SRC - List of source files to statically analyze
|
|
#
|
|
# OPTIONAL PARAMETERS:
|
|
#
|
|
# CPPCHECK_INCLUDES - Extra include paths to search for missing
|
|
# header files
|
|
# CPPCHECK_EXCLUDES - Source file paths to exclude checking (can be
|
|
# a path fragment if desired)
|
|
# CPPCHECK_MSG_TEMPLATE - Template for cppcheck error and warning output
|
|
# CPPCHECK_ENABLE - General cppcheck category checks to enable
|
|
# CPPCHECK_SUPPRESS - Specific cppcheck warnings to disable by ID
|
|
# CPPCHECK_FAIL_ON_WARNING - Set to Y to fail the build on cppcheck
|
|
# warnings, N to continue even if warnings occur
|
|
# CPPCHECK_QUIET - Enable cppcheck verbose or quiet output mode
|
|
# CPPCHECK_FLAGS - Additional flags to pass to cppcheck
|
|
#
|
|
# PROVIDED VARIABLES:
|
|
#
|
|
# (None)
|
|
#
|
|
# PROVIDED MACROS:
|
|
#
|
|
# (None)
