# SYNOPSIS
|
||||
#
|
||||
# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
|
||||
# added in between.
|
||||
#
|
||||
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
|
||||
# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
|
||||
# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
|
||||
# FLAG.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

# SYNOPSIS

#
|
||||
# AX_CFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
|
||||
# AX_CXXFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]

# AX_FCFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
|

#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Try to find a compiler option that enables most reasonable warnings.
|
||||
#
|
||||
# For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
|
||||
# is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
|
||||
#
|
||||
# Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
|
||||
# HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
|
||||
# Intel compilers. For a given compiler, the Fortran flags are much more
|
||||
# experimental than their C equivalents.
|
||||
#
|
||||
# - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
|
||||
# - $2 add-value-if-not-found : nothing
|
||||
# - $3 action-if-found : add value to shellvariable
|
||||
# - $4 action-if-not-found : nothing
|
||||
#
|
||||
# NOTE: These macros depend on AX_APPEND_FLAG.

#
|

# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the current language's compiler
|
||||
# or gives an error. (Warnings, however, are ignored)
|
||||
#
|
||||
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
||||
# success/failure.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the current language's default
|
||||
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
||||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
||||
# force the compiler to issue an error when a bad flag is given.
|
||||
#
|
||||
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

# SYNOPSIS

#
|
||||
# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for the presence of an --enable-debug option to configure, with
|
||||
# the specified default value used when the option is not present. Return
|
||||
# the value in the variable $ax_enable_debug.
|
||||
#
|
||||
# Specifying 'yes' adds '-g -O0' to the compilation flags for all
|
||||
# languages. Specifying 'info' adds '-g' to the compilation flags.
|
||||
# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
|
||||
# the linking flags. Otherwise, nothing is added.
|
||||
#
|
||||
# Define the variables listed in the second argument if debug is enabled,
|
||||
# defaulting to no variables. Defines the variables listed in the third
|
||||
# argument if debug is disabled, defaulting to NDEBUG. All lists of
|
||||
# variables should be space-separated.
|
||||
#
|
||||
# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
|
||||
# Should be invoked prior to any AC_PROG_* compiler checks.
|
||||
#
|
||||
# IS-RELEASE can be used to change the default to 'no' when making a
|
||||
# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. 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.

# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_GNU_MAKE()
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro searches for a GNU version of make. If a match is found:
|
||||
#
|
||||
# * The makefile variable `ifGNUmake' is set to the empty string, otherwise
|
||||
# it is set to "#". This is useful for including a special features in a
|
||||
# Makefile, which cannot be handled by other versions of make.
|
||||
# * The variable `_cv_gnu_make_command` is set to the command to invoke
|
||||
# GNU make if it exists, the empty string otherwise.
|
||||
# * The variable `ax_cv_gnu_make_command` is set to the command to invoke
|
||||
# GNU make by copying `_cv_gnu_make_command`, otherwise it is unset.
|
||||
# * If GNU Make is found, its version is extracted from the output of
|
||||
# `make --version` as the last field of a record of space-separated
|
||||
# columns and saved into the variable `ax_check_gnu_make_version`.
|
||||
#
|
||||
# Here is an example of its use:
|
||||
#
|
||||
# Makefile.in might contain:
|
||||
#
|
||||
# # A failsafe way of putting a dependency rule into a makefile
|
||||
# $(DEPEND):
|
||||
# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
|
||||
#
|
||||
# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
|
||||
# @ifGNUmake@ include $(DEPEND)
|
||||
# @ifGNUmake@ endif
|
||||
#
|
||||
# Then configure.in would normally contain:
|
||||
#
|
||||
# AX_CHECK_GNU_MAKE()
|
||||
# AC_OUTPUT(Makefile)
|
||||
#
|
||||
# Then perhaps to cause gnu make to override any other make, we could do
|
||||
# something like this (note that GNU make always looks for GNUmakefile
|
||||
# first):
|
||||
#
|
||||
# if ! test x$_cv_gnu_make_command = x ; then
|
||||
# mv Makefile GNUmakefile
|
||||
# echo .DEFAULT: > Makefile ;
|
||||
# echo \ $_cv_gnu_make_command \$@ >> Makefile;
|
||||
# fi
|
||||
#
|
||||
# Then, if any (well almost any) other make is called, and GNU make also
|
||||
# exists, then the other make wraps the GNU make.

# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the linker or gives an error.
|
||||
# (Warnings, however, are ignored)
|
||||
#
|
||||
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
||||
# success/failure.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the linker's default flags
|
||||
# when the check is done. The check is thus made with the flags: "LDFLAGS
|
||||
# EXTRA-FLAGS FLAG". This can for example be used to force the linker to
|
||||
# issue an error when a bad flag is given.
|
||||
#
|
||||
# INPUT gives an alternative input source to AC_LINK_IFELSE.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.

#
|
||||
# SYNOPSIS
|
||||
#
|
||||
# AX_CODE_COVERAGE()
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
|
||||
# CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LDFLAGS which should be
|
||||
# included in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LDFLAGS variables of
|
||||
# every build target (program or library) which should be built with code
|
||||
# coverage support. Also defines CODE_COVERAGE_RULES which should be
|
||||
# substituted in your Makefile; and $enable_code_coverage which can be
|
||||
# used in subsequent configure output. CODE_COVERAGE_ENABLED is defined
|
||||
# and substituted, and corresponds to the value of the
|
||||
# --enable-code-coverage option, which defaults to being disabled.
|
||||
#
|
||||
# Test also for gcov program and create GCOV variable that could be
|
||||
# substituted.
|
||||
#
|
||||
# Note that all optimisation flags in CFLAGS must be disabled when code
|
||||
# coverage is enabled.
|
||||
#
|
||||
# Usage example:
|
||||
#
|
||||
# configure.ac:
|
||||
#
|
||||
# AX_CODE_COVERAGE
|
||||
#
|
||||
# Makefile.am:
|
||||
#
|
||||
# @CODE_COVERAGE_RULES@
|
||||
# my_program_LIBS = ... $(CODE_COVERAGE_LDFLAGS) ...
|
||||
# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
|
||||
# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
|
||||
# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
|
||||
#
|
||||
# This results in a "check-code-coverage" rule being added to any
|
||||
# Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module
|
||||
# has been configured with --enable-code-coverage). Running `make
|
||||
# check-code-coverage` in that directory will run the module's test suite
|
||||
# (`make check`) and build a code coverage report detailing the code which
|
||||
# was touched, then print the URI for the report.
|
||||
#
|
||||
# This code was derived from Makefile.decl in GLib, originally licenced
|
||||
# under LGPLv2.1+.

# SYNOPSIS

#

# AX_CONFIGURE_ARGS
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Helper macro for AX_ENABLE_BUILDDIR.
|
||||
#
|
||||
# The traditional way of starting a subdir-configure is running the script
|
||||
# with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
|
||||
# to rely on eval'ing $ac_configure_args however some old autoconf
|
||||
# versions do not provide that. To ensure maximum portability of autoconf
|
||||
# extension macros this helper can be AC_REQUIRE'd so that
|
||||
# $ac_configure_args will alsways be present.
|
||||
#
|
||||
# Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
|
||||
# spoiled now and must be replaced by "eval + exit $?".
|
||||
#
|
||||
# Example:
|
||||
#
|
||||
# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
|
||||
# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
|
||||
# eval $SHELL $ac_configure_args || exit $?
|
||||
# ...])

# SYNOPSIS
|
||||
#
|
||||
# AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# If the current configure was run within the srcdir then we move all
|
||||
# configure-files into a subdir and let the configure steps continue
|
||||
# there. We provide an option --disable-builddir to suppress the move into
|
||||
# a separate builddir.
|
||||
#
|
||||
# Defaults:
|
||||
#
|
||||
# $1 = $host (overridden with $HOST)
|
||||
# $2 = Makefile.mk
|
||||
# $3 = -all
|
||||
#
|
||||
# This macro must be called before AM_INIT_AUTOMAKE. It creates a default
|
||||
# toplevel srcdir Makefile from the information found in the created
|
||||
# toplevel builddir Makefile. It just copies the variables and
|
||||
# rule-targets, each extended with a default rule-execution that recurses
|
||||
# into the build directory of the current "HOST". You can override the
|
||||
# auto-dection through `config.guess` and build-time of course, as in
|
||||
#
|
||||
# make HOST=i386-mingw-cross
|
||||
#
|
||||
# which can of course set at configure time as well using
|
||||
#
|
||||
# configure --host=i386-mingw-cross
|
||||
#
|
||||
# After the default has been created, additional rules can be appended
|
||||
# that will not just recurse into the subdirectories and only ever exist
|
||||
# in the srcdir toplevel makefile - these parts are read from the $2 =
|
||||
# Makefile.mk file
|
||||
#
|
||||
# The automatic rules are usually scanning the toplevel Makefile for lines
|
||||
# like '#### $host |$builddir' to recognize the place where to recurse
|
||||
# into. Usually, the last one is the only one used. However, almost all
|
||||
# targets have an additional "*-all" rule which makes the script to
|
||||
# recurse into _all_ variants of the current HOST (!!) setting. The "-all"
|
||||
# suffix can be overriden for the macro as well.
|
||||
#
|
||||
# a special rule is only given for things like "dist" that will copy the
|
||||
# tarball from the builddir to the sourcedir (or $(PUB)) for reason of
|
||||
# convenience.

# SYNOPSIS
|
||||
#
|
||||
# AX_EXTEND_SRCDIR
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# The AX_EXTEND_SRCDIR macro extends $srcdir by one path component.
|
||||
#
|
||||
# As an example, when working in /home/michael/i3-4.12/build and calling
|
||||
# ../configure, your $srcdir is "..". After calling AX_EXTEND_SRCDIR,
|
||||
# $srcdir will be set to "../../i3-4.12".
|
||||
#
|
||||
# The result of extending $srcdir is that filenames (e.g. in the output of
|
||||
# the "backtrace" gdb command) will include one more path component of the
|
||||
# absolute source path. The additional path component makes it easy for
|
||||
# users to recognize which files belong to the PACKAGE, and -- provided a
|
||||
# dist tarball was unpacked -- which version of PACKAGE was used.
|
||||
#
|
||||
# As an example, in "backtrace", you will see:
|
||||
#
|
||||
# #0 main (argc=1, argv=0x7fffffff1fc8) at ../../i3-4.12/src/main.c:187
|
||||
#
|
||||
# instead of:
|
||||
#
|
||||
# #0 main (argc=1, argv=0x7fffffff1fc8) at ../src/main.c:187
|
||||
#
|
||||
# In case your code uses the __FILE__ preprocessor directive to refer to
|
||||
# the filename of the current source file (e.g. in debug messages), using
|
||||
# the extended path might be undesirable. For this purpose,
|
||||
# AX_EXTEND_SRCDIR defines the output variable AX_EXTEND_SRCDIR_CPPFLAGS,
|
||||
# which can be added to AM_CPPFLAGS in Makefile.am in order to define the
|
||||
# preprocessor directive STRIPPED__FILE__. As an example, when compiling
|
||||
# the file "../../i3-4.12/src/main.c", STRIPPED__FILE__ evaluates to
|
||||
# "main.c".
|
||||
#
|
||||
# There are some caveats: When $srcdir is "." (i.e. when ./configure was
|
||||
# called instead of ../configure in a separate build directory),
|
||||
# AX_EXTEND_SRCDIR will still extend $srcdir, but the intended effect will
|
||||
# not be achieved because of the way automake specifies file paths:
|
||||
# automake defines COMPILE to use "`test -f '$source' || echo
|
||||
# '\$(srcdir)/'`$source" in order to prefer files in the current directory
|
||||
# over specifying $srcdir explicitly.
|
||||
#
|
||||
# The AX_EXTEND_SRCDIR author is not aware of any way to influence this
|
||||
# automake behavior. Patches very welcome.
|
||||
#
|
||||
# To work around this issue, you can use AX_ENABLE_BUILDDIR i.e. by adding
|
||||
# the following code to configure.ac:
|
||||
#
|
||||
# AX_ENABLE_BUILDDIR
|
||||
# dnl ...
|
||||
# AX_EXTEND_SRCDIR
|
||||
#
|
||||
# Then also add this bit to Makefile.am (if you wish to use
|
||||
# STRIPPED__FILE__ in your code):
|
||||
#
|
||||
# AM_CPPFLAGS = @AX_EXTEND_SRCDIR_CPPFLAGS@

# AX_REQUIRE_DEFINED(MACRO)
|

#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
|
||||
# been defined and thus are available for use. This avoids random issues
|
||||
# where a macro isn't expanded. Instead the configure script emits a
|
||||
# non-fatal:
|
||||
#
|
||||
# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
|
||||
#
|
||||
# It's like AC_REQUIRE except it doesn't expand the required macro.
|
||||
#
|
||||
# Here's an example:
|
||||
#
|
||||
# AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

# SYNOPSIS

#
|
||||
# AX_SANITIZERS([SANITIZERS], [ENABLED-BY-DEFAULT], [ACTION-SUCCESS])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Offers users to enable one or more sanitizers (see
|
||||
# https://github.com/google/sanitizers) with the corresponding
|
||||
# --enable-<sanitizer>-sanitizer option.
|
||||
#
|
||||
# SANITIZERS is a whitespace-separated list of sanitizers to offer via
|
||||
# --enable-<sanitizer>-sanitizer options, e.g. "address memory" for the
|
||||
# address sanitizer and the memory sanitizer. If SANITIZERS is not specified,
|
||||
# all known sanitizers to AX_SANITIZERS will be offered, which at the time of
|
||||
# writing are "address memory undefined".
|
||||
# NOTE that SANITIZERS is expanded at autoconf time, not at configure time,
|
||||
# i.e. you cannot use shell variables in SANITIZERS.
|
||||
#
|
||||
# ENABLED-BY-DEFAULT is a whitespace-separated list of sanitizers which
|
||||
# should be enabled by default, e.g. "memory undefined". Note that not all
|
||||
# sanitizers can be combined, e.g. memory sanitizer cannot be enabled when
|
||||
# address sanitizer is already enabled.
|
||||
# Set ENABLED-BY-DEFAULT to a single whitespace in order to disable all
|
||||
# sanitizers by default.
|
||||
# ENABLED-BY-DEFAULT is expanded at configure time, so you can use shell
|
||||
# variables.
|
||||
#
|
||||
# ACTION-SUCCESS allows to specify shell commands to execute on success, i.e.
|
||||
# when one of the sanitizers was successfully enabled. This is a good place
|
||||
# to call AC_DEFINE for any precompiler constants you might need to make your
|
||||
# code play nice with sanitizers.
|
||||
#
|
||||
# The variable ax_enabled_sanitizers contains a whitespace-separated list of
|
||||
# all enabled sanitizers, so that you can print them at the end of configure,
|
||||
# if you wish.
|
||||
#
|
||||
# The additional --enable-sanitizers option allows users to enable/disable
|
||||
# all sanitizers, effectively overriding ENABLED-BY-DEFAULT.

||||
