247 # Depending on the value of --enable-compile-warnings, different compiler
248 # warnings are checked to see if they work with the current compiler and,
249 # if so, are appended to CFLAGS-VARIABLE and LDFLAGS-VARIABLE. This
250 # allows a consistent set of baseline compiler warnings to be used across
251 # a code base, irrespective of any warnings enabled locally by individual
252 # developers. By standardising the warnings used by all developers of a
253 # project, the project can commit to a zero-warnings policy, using -Werror
254 # to prevent compilation if new warnings are introduced. This makes
255 # catching bugs which are flagged by warnings a lot easier.
257 # By providing a consistent --enable-compile-warnings argument across all
258 # projects using this macro, continuous integration systems can easily be
259 # configured the same for all projects. Automated systems or build
260 # systems aimed at beginners may want to pass the --disable-Werror
261 # argument to unconditionally prevent warnings being fatal.
263 # --enable-compile-warnings can take the values:
265 # * no: Base compiler warnings only; not even -Wall.
266 # * yes: The above, plus a broad range of useful warnings.
267 # * error: The above, plus -Werror so that all warnings are fatal.
268 # Use --disable-Werror to override this and disable fatal
271 # The set of base and enabled flags can be augmented using the
272 # EXTRA-*-CFLAGS and EXTRA-*-LDFLAGS variables, which are tested and
273 # appended to the output variable if --enable-compile-warnings is not
274 # "no". Flags should not be disabled using these arguments, as the entire
275 # point of AX_COMPILER_FLAGS is to enforce a consistent set of useful
276 # compiler warnings on code, using warnings which have been chosen for low
277 # false positive rates. If a compiler emits false positives for a
278 # warning, a #pragma should be used in the code to disable the warning
281 # https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/Diagnostic-Pragmas.html#Diagnostic-Pragmas
283 # The EXTRA-* variables should only be used to supply extra warning flags,
284 # and not general purpose compiler flags, as they are controlled by
285 # configure options such as --disable-Werror.
287 # IS-RELEASE can be used to disable -Werror when making a release, which
288 # is useful for those hairy moments when you just want to get the release
289 # done as quickly as possible. Set it to "yes" to disable -Werror. By
290 # default, it uses the value of $ax_is_release, so if you are using the
291 # AX_IS_RELEASE macro, there is no need to pass this parameter. For
294 # AX_IS_RELEASE([git-directory])
295 # AX_COMPILER_FLAGS()
297 # CFLAGS-VARIABLE defaults to WARN_CFLAGS, and LDFLAGS-VARIABLE defaults
298 # to WARN_LDFLAGS. Both variables are AC_SUBST-ed by this macro, but must
299 # be manually added to the CFLAGS and LDFLAGS variables for each target in
302 # If C++ language support is enabled with AC_PROG_CXX, which must occur
303 # before this macro in configure.ac, warning flags for the C++ compiler
304 # are AC_SUBST-ed as WARN_CXXFLAGS, and must be manually added to the
305 # CXXFLAGS variables for each target in the code base. EXTRA-*-CFLAGS can
306 # be used to augment the base and enabled flags.
308 # Warning flags for g-ir-scanner (from GObject Introspection) are
309 # AC_SUBST-ed as WARN_SCANNERFLAGS. This variable must be manually added
310 # to the SCANNERFLAGS variable for each GIR target in the code base. If
311 # extra g-ir-scanner flags need to be enabled, the AX_COMPILER_FLAGS_GIR
312 # macro must be invoked manually.
314 # AX_COMPILER_FLAGS may add support for other tools in future, in addition
315 # to the compiler and linker. No extra EXTRA-* variables will be added
316 # for those tools, and all extra support will still use the single
317 # --enable-compile-warnings configure option. For finer grained control
318 # over the flags for individual tools, use AX_COMPILER_FLAGS_CFLAGS,
319 # AX_COMPILER_FLAGS_LDFLAGS and AX_COMPILER_FLAGS_* for new tools.

322 # automatically appended to the preceding non-UNUSED variable. They should

1049 # it makes $ac_aux_dir quite unusable in subdirectories: in the top

1051 # relative path needs to be adjusted first.

1062 # harmless because $srcdir is '.', but things will broke when you
1063 # start a VPATH build or use an absolute $srcdir.
1065 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
