# 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. |

|
# Try to find a compiler option that enables most reasonable warnings. |

# SYNOPSIS |

# |

|
# 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. |

|
# 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+. |

||||
|
# 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 $?". |

# 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_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. |
||||
|
# |
||||
|
