# 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.)

# This macro figures out how to build C programs using POSIX threads. It

||||
# 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
|

# 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:

# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute

# constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to

# (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

|

# on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
