# SYNOPSIS

#
|
||||
# AX_CHECK_SIGN (TYPE, [ACTION-IF-SIGNED], [ACTION-IF-UNSIGNED], [INCLUDES])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Checks whether TYPE is signed or not. If no INCLUDES are specified, the
|
||||
# default includes are used. If ACTION-IF-SIGNED is given, it is
|
||||
# additional shell code to execute when the type is signed. If
|
||||
# ACTION-IF-UNSIGNED is given, it is executed when the type is unsigned.
|
||||
#
|
||||
# This macro assumes that the type exists. Therefore the existence of the
|
||||
# type should be checked before calling this macro. For example:
|
||||
#
|
||||
# AC_CHECK_HEADERS([wchar.h])
|
||||
# AC_CHECK_TYPE([wchar_t],,[ AC_MSG_ERROR([Type wchar_t not found.]) ])
|
||||
# AX_CHECK_SIGN([wchar_t],
|
||||
# [ AC_DEFINE(WCHAR_T_SIGNED, 1, [Define if wchar_t is signed]) ],
|
||||
# [ AC_DEFINE(WCHAR_T_UNSIGNED, 1, [Define if wchar_t is unsigned]) ], [
|
||||
# #ifdef HAVE_WCHAR_H
|
||||
# #include <wchar.h>
|

# #endif

# SYNOPSIS

#
|
||||
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check for baseline language coverage in the compiler for the specified
|
||||
# version of the C++ standard. If necessary, add switches to CXX and
|
||||
# CXXCPP to enable support. VERSION may be '11' (for the C++11 standard)
|
||||
# or '14' (for the C++14 standard).
|
||||
#
|
||||
# The second argument, if specified, indicates whether you insist on an
|
||||
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
|
||||
# -std=c++11). If neither is specified, you get whatever works, with
|
||||
# preference for an extended mode.
|
||||
#
|
||||
# The third argument, if specified 'mandatory' or if left unspecified,
|
||||
# indicates that baseline support for the specified C++ standard is
|
||||
# required and that the macro should error out if no mode with that
|
||||
# support is found. If specified 'optional', then configuration proceeds
|
||||
# regardless, after defining HAVE_CXX${VERSION} if and only if a
|
||||
# supporting mode is found.

#
|

# SYNOPSIS
|
||||
#
|
||||
# AX_LIB_MYSQL([MINIMUM-VERSION])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro provides tests of availability of MySQL client library
|
||||
# of particular version or newer.
|
||||
#
|
||||
# AX_LIB_MYSQL macro takes only one argument which is optional. If
|
||||
# there is no required version passed, then macro does not run
|
||||
# version test.
|
||||
#
|
||||
# The --with-mysql option takes one of three possible values:
|
||||
#
|
||||
# no - do not check for MySQL client library
|
||||
#
|
||||
# yes - do check for MySQL library in standard locations
|
||||
# (mysql_config should be in the PATH)
|
||||
#
|
||||
# path - complete path to mysql_config utility, use this option if
|
||||
# mysql_config can't be found in the PATH
|
||||
#
|
||||
# This macro calls:
|
||||
#
|
||||
# AC_SUBST(MYSQL_CFLAGS)
|
||||
# AC_SUBST(MYSQL_LDFLAGS)
|
||||
# AC_SUBST(MYSQL_LIBS)
|
||||
# AC_SUBST(MYSQL_VERSION)
|
||||
#
|
||||
# And sets:
|
||||
#
|
||||
# HAVE_MYSQL
|
||||
#

||||

# SYNOPSIS
|
||||
#
|
||||
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro figures out how to build C programs using POSIX threads. It
|
||||
# sets the PTHREAD_LIBS output variable to the threads library and linker
|
||||
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
|
||||
# flags that are needed. (The user can also force certain compiler
|
||||
# flags/libs to be tested by setting these environment variables.)
|
||||
#
|
||||
# Also sets PTHREAD_CC to any special C compiler that is needed for
|
||||
# multi-threaded programs (defaults to the value of CC otherwise). (This
|
||||
# is necessary on AIX to use the special cc_r compiler alias.)
|
||||
#
|
||||
# NOTE: You are assumed to not only compile your program with these flags,
|
||||
# but also to link with them as well. For example, you might link with
|
||||
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
|
||||
#
|
||||
# If you are only building threaded programs, you may wish to use these
|
||||
# variables in your default LIBS, CFLAGS, and CC:
|
||||
#
|
||||
# LIBS="$PTHREAD_LIBS $LIBS"
|
||||
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
||||
# CC="$PTHREAD_CC"
|
||||
#
|
||||
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
|
||||
# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
|
||||
# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
||||
#
|
||||
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
|
||||
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
|
||||
# PTHREAD_CFLAGS.
|
||||
#
|
||||
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
|
||||
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
|
||||
# is not found. If ACTION-IF-FOUND is not specified, the default action
|
||||
# will define HAVE_PTHREAD.
|
||||
#
|
||||
# Please let the authors know if this macro fails on any platform, or if
|
||||
# you have any other suggestions or comments. This macro was based on work
|
||||
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
|
||||
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
|
||||
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
|
||||
# grateful for the helpful feedback of numerous users.

# serial 5 lt~obsolete.m4
|
||||
|
||||
# These exist entirely to fool aclocal when bootstrapping libtool.
|
||||
#
|
||||
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
|
||||
# which have later been changed to m4_define as they aren't part of the
|
||||
# exported API, or moved to Autoconf or Automake where they belong.
|
||||
#
|
||||
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
|
||||
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
|
||||
# using a macro with the same name in our local m4/libtool.m4 it'll
|
||||
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
|
||||
# and doesn't know about Autoconf macros at all.)
|
||||
#
|
||||
# So we provide this file, which has a silly filename so it's always
|
||||
# included after everything else. This provides aclocal with the
|
||||
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
|
||||
# because those macros already exist, or will be overwritten later.
|
||||
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
|
||||
#
|
||||
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
|
||||
# Yes, that means every name once taken will need to remain here until
|
||||
# we give up compatibility with versions before 1.7, at which point
|
||||
# we need to keep only those names which we still refer to.
|
||||
|
||||
# This is to help aclocal find these macros, as it can't see m4_define.
