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 link it with them as well. e.g. you should link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threads programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name +# (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# 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.

Due to the various number of +# minor-version numbers that can exist, and the fact that string +# comparisons are not compatible with numeric comparisons, this is not +# necessarily trivial to do in a autoconf script. This macro makes doing +# these comparisons easy. +# +# The six basic comparisons are available, as well as checking equality +# limited to a certain number of minor-version levels. +# +# The operator OP determines what type of comparison to do, and can be one +# of: +# +# eq - equal (test A == B) +# ne - not equal (test A != B) +# le - less than or equal (test A <= B) +# ge - greater than or equal (test A >= B) +# lt - less than (test A < B) +# gt - greater than (test A > B) +# +# Additionally, the eq and ne operator can have a number after it to limit +# the test to that number of minor versions. +# +# eq0 - equal up to the length of the shorter version +# ne0 - not equal up to the length of the shorter version +# eqN - equal up to N sub-version levels +# neN - not equal up to N sub-version levels +# +# When the condition is true, shell commands ACTION-IF-TRUE are run, +# otherwise shell commands ACTION-IF-FALSE are run. The environment +# variable 'ax_compare_version' is always set to either 'true' or 'false' +# as well. +# +# Examples: +# +# AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8]) +# AX_COMPARE_VERSION([3.15],[lt],[3.15.8]) +# +# would both be true. +# +# AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8]) +# AX_COMPARE_VERSION([3.15],[gt],[3.15.8]) +# +# would both be false. +# +# AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8]) +# +# would be true because it is only comparing two minor versions. +# +# AX_COMPARE_VERSION([3.15.7],[eq0],[3.15]) +# +# would be true because it is only comparing the lesser number of minor +# versions of the two values. +# +# Note: The characters that separate the version numbers do not matter. An +# empty string is the same as version 0. OP is evaluated by autoconf, not +# configure, so must be a string, not a variable. +# +# The author would like to acknowledge Guido Draheim whose advice about +# the m4_case and m4_ifvaln functions make this macro only include the +# portions necessary to perform the specific comparison specified by the +# OP argument in the final configure script. +# +# LICENSE +# +# Copyright (c) 2008 Tim Toolan +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved. + + +# =========================================================================== +# http://www.nongnu.org/autoconf-archive/ax_compiler_vendor.html +# =========================================================================== +# +# SYNOPSIS +# +# AX_COMPILER_VENDOR +# +# DESCRIPTION +# +# Determine the vendor of the C/C++ compiler, e.g., gnu, intel, ibm, sun, +# hp, borland, comeau, dec, cray, kai, lcc, metrowerks, sgi, microsoft, +# watcom, etc. The vendor is returned in the cache variable +# $ax_cv_c_compiler_vendor for C and $ax_cv_cxx_compiler_vendor for C++. +# +# LICENSE +# +# Copyright (c) 2008 Steven G.
