# 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.
