Return the value in the variable +# $ax_enable_compile_warnings. +# +# Depending on the value of --enable-compile-warnings, different compiler +# warnings are checked to see if they work with the current compiler and, +# if so, are appended to CFLAGS-VARIABLE and LDFLAGS-VARIABLE. This +# allows a consistent set of baseline compiler warnings to be used across +# a code base, irrespective of any warnings enabled locally by individual +# developers. By standardising the warnings used by all developers of a +# project, the project can commit to a zero-warnings policy, using -Werror +# to prevent compilation if new warnings are introduced. This makes +# catching bugs which are flagged by warnings a lot easier. +# +# By providing a consistent --enable-compile-warnings argument across all +# projects using this macro, continuous integration systems can easily be +# configured the same for all projects. Automated systems or build +# systems aimed at beginners may want to pass the --disable-Werror +# argument to unconditionally prevent warnings being fatal. +# +# --enable-compile-warnings can take the values: +# +# * no: Base compiler warnings only; not even -Wall. +# * yes: The above, plus a broad range of useful warnings. +# * error: The above, plus -Werror so that all warnings are fatal. +# Use --disable-Werror to override this and disable fatal +# warnings. +# +# The set of base and enabled flags can be augmented using the +# EXTRA-*-CFLAGS and EXTRA-*-LDFLAGS variables, which are tested and +# appended to the output variable if --enable-compile-warnings is not +# "no". Flags should not be disabled using these arguments, as the entire +# point of AX_COMPILER_FLAGS is to enforce a consistent set of useful +# compiler warnings on code, using warnings which have been chosen for low +# false positive rates. If a compiler emits false positives for a +# warning, a #pragma should be used in the code to disable the warning +# locally. See: +# +# https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/Diagnostic-Pragmas.html#Diagnostic-Pragmas +# +# The EXTRA-* variables should only be used to supply extra warning flags, +# and not general purpose compiler flags, as they are controlled by +# configure options such as --disable-Werror. +# +# IS-RELEASE can be used to disable -Werror when making a release, which +# is useful for those hairy moments when you just want to get the release +# done as quickly as possible. Set it to "yes" to disable -Werror. By +# default, it uses the value of $ax_is_release, so if you are using the +# AX_IS_RELEASE macro, there is no need to pass this parameter. For +# example: +# +# AX_IS_RELEASE([git-directory]) +# AX_COMPILER_FLAGS() +# +# CFLAGS-VARIABLE defaults to WARN_CFLAGS, and LDFLAGS-VARIABLE defaults +# to WARN_LDFLAGS. Both variables are AC_SUBST-ed by this macro, but must +# be manually added to the CFLAGS and LDFLAGS variables for each target in +# the code base. +# +# If C++ language support is enabled with AC_PROG_CXX, which must occur +# before this macro in configure.ac, warning flags for the C++ compiler +# are AC_SUBST-ed as WARN_CXXFLAGS, and must be manually added to the +# CXXFLAGS variables for each target in the code base. EXTRA-*-CFLAGS can +# be used to augment the base and enabled flags. +# +# Warning flags for g-ir-scanner (from GObject Introspection) are +# AC_SUBST-ed as WARN_SCANNERFLAGS. This variable must be manually added +# to the SCANNERFLAGS variable for each GIR target in the code base. If +# extra g-ir-scanner flags need to be enabled, the AX_COMPILER_FLAGS_GIR +# macro must be invoked manually. +# +# AX_COMPILER_FLAGS may add support for other tools in future, in addition +# to the compiler and linker. No extra EXTRA-* variables will be added +# for those tools, and all extra support will still use the single +# --enable-compile-warnings configure option. For finer grained control +# over the flags for individual tools, use AX_COMPILER_FLAGS_CFLAGS, +# AX_COMPILER_FLAGS_LDFLAGS and AX_COMPILER_FLAGS_* for new tools. +# +# The UNUSED variables date from a previous version of this macro, and are +# automatically appended to the preceding non-UNUSED variable.
