# ===========================================================================
#
# SYNOPSIS
#
# AX_AM_JOBSERVER([default_value])
#
# DESCRIPTION
#
# Enables the use of make's jobserver for the purpose of parallel building
# by passing the -j option to make.
#
# The option --enable-jobserver is added to configure which can accept a
# yes, no, or an integer. The integer is the number of separate jobs to
# allow. If 'yes' is given, then the is assumed to be one more than the
# number of CPUs (determined through AX_COUNT_CPUS). If the value of no is
# given, then the jobserver is disabled. The default value is given by the
# first argument of the macro, or 'yes' if the argument is omitted.
#
# This macro makes use of AX_AM_MACROS, so you must add the following line
#
# @INC_AMINCLUDE@
#
# to your Makefile.am files.

#
# SYNOPSIS
#
# AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
# For every FLAG1, FLAG2 it is checked whether the compiler works with the
# flag. If it does, the flag is added FLAGS-VARIABLE
#
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
# CFLAGS) is used. During the check the flag is always added to the
# current language's flags.
#
# 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: This macro depends on the AX_APPEND_FLAG and
# AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
# AX_APPEND_LINK_FLAGS.

# SYNOPSIS
#
# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])

# DESCRIPTION
#
# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space

#
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.

#
# SYNOPSIS
#
# AX_CHECK_LIBRARY(VARIABLE-PREFIX, HEADER-FILE, LIBRARY-FILE,
# [ACTION-IF-FOUND], [ACTION-IF-NOT_FOUND])
#
# DESCRIPTION
#
# Provides a generic test for a given library, similar in concept to the
# PKG_CHECK_MODULES macro used by pkg-config.
#
# Most simplest libraries can be checked against simply through the
# presence of a header file and a library to link to. This macro allows to
# wrap around the test so that it doesn't have to be recreated each time.
#
# Rather than define --with-$LIBRARY arguments, it uses variables in the
# same way that PKG_CHECK_MODULES does. It doesn't, though, use the same
# names, since you shouldn't provide a value for LIBS or CFLAGS but rather
# for LDFLAGS and CPPFLAGS, to tell the linker and compiler where to find
# libraries and headers respectively.
#
# If the library is find, HAVE_PREFIX is defined, and in all cases
# PREFIX_LDFLAGS and PREFIX_CPPFLAGS are substituted.
#
# Example:
#
# AX_CHECK_LIBRARY([LIBEVENT], [event.h], [event], [],
# [AC_MSG_ERROR([Unable to find libevent])])

# DESCRIPTION
#
# Attempt to count the number of logical processor cores (including
# virtual and HT cores) currently available to use on the machine and
# place detected value in CPU_COUNT variable.
#
# On successful detection, ACTION-IF-DETECTED is executed if present. If
# the detection fails, then ACTION-IF-NOT-DETECTED is triggered. The
# default ACTION-IF-NOT-DETECTED is to set CPU_COUNT to 1.

#
# SYNOPSIS
#
# AX_CREATE_GENERIC_CONFIG [(PACKAGEnlibs [, VERSION])]
#
# DESCRIPTION
#
# Creates a generic PACKAGE-config file that has all the things that you
# want, hmm, well, at least it has --cflags, --version, --libs. Ahhm, did
# you see ax_path_generic in the autoconf-archive? ;-)
#
# this macros saves you all the typing for a pkg-config.in script, you
# don't even need to distribute one along. Place this macro in your
# configure.ac, et voila, you got one that you want to install.
#
# oh, btw, if the first arg looks like "mylib -lwhat' then it will go to
# be added to the --libs, and mylib is extracted.
#
# the defaults: $1 = $PACKAGE $LIBS $2 = $VERSION there is also an
# AC_SUBST(GENERIC_CONFIG) that will be set to the name of the file that
# we did output in this macro. Use as:
#
# install-exec-local: install-generic-config
#
# install-generic-config:
# $(mkinstalldirs) $(DESTDIR)$(bindir)
# $(INSTALL_SCRIPT) @GENERIC_CONFIG@ $(DESTDIR)$(bindir)

# 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.

# (Note 2: On some systems, notably Darwin, -pthread is not needed

# when source code is being compiled.
#
# Problem is, this is at odds with the way Automake and most other
# C build frameworks function, which is that the same flags used in
# compilation (CFLAGS) are also used in linking. Many systems
# supported by AX_PTHREAD require exactly this for POSIX threads
# support, and in fact it is often not straightforward to specify a
# flag that is used only in the compilation phase and not in
# linking. Such a scenario is extremely rare in practice.
#
# Even though use of the -pthread flag in linking would only print

#
# SYNOPSIS
#
# 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_TLS([action-if-found], [action-if-not-found])
#
# DESCRIPTION
#
# Provides a test for the compiler support of thread local storage (TLS)
# extensions. Defines TLS if it is found. Currently knows about GCC/ICC
# and MSVC. I think SunPro uses the same as GCC, and Borland apparently
# supports either.

dnl @synopsis LIB_SOCKET_NSL
dnl
dnl This macro figures out what libraries are required on this platform
dnl to link sockets programs.
dnl
dnl The common cases are not to need any extra libraries, or to need
dnl -lsocket and -lnsl. We need to avoid linking with libnsl unless we
dnl need it, though, since on some OSes where it isn't necessary it
dnl will totally break networking. Unisys also includes gethostbyname()
dnl in libsocket but needs libnsl for socket().
