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. They should # be left empty in new uses of the macro. # # LICENSE # # Copyright (c) 2014, 2015 Philip Withnall # Copyright (c) 2015 David King # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.
