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. We are also # grateful for the helpful feedback of numerous users. # # LICENSE # # Copyright (c) 2008 Steven G.

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.
