# SYNOPSIS
|
|
#
|
|
# AX_PKG_CHECK_MODULES(PREFIX, PUBLIC-MODULES, PRIVATE-MODULES, [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND], [PUBLIC-VARIABLE], [PRIVATE-VARIABLE])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# A wrapper around PKG_CHECK_MODULES which splits the list of modules into
|
|
# public and private dependencies, and produces two variables listing the
|
|
# dependencies across all invocations of AX_PKG_CHECK_MODULES. These two
|
|
# variables are exposed via AC_SUBST, and should be used in a pkg-config
|
|
# file as the substituted values for Requires and Requires.private.
|
|
#
|
|
# The PREFIX, PUBLIC-MODULES and PRIVATE-MODULES arguments should be
|
|
# specified as for PKG_CHECK_MODULES, with the concatenation of
|
|
# PUBLIC-MODULES and PRIVATE-MODULES equaling the LIST-OF-MODULES from
|
|
# PKG_CHECK_MODULES. The ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
|
|
# arguments are optional, and should also be specified as for
|
|
# PKG_CHECK_MODULES. ACTION-IF-FOUND is evaluated if the full
|
|
# LIST-OF-MODULES is found; ACTION-IF-NOT-FOUND similarly.
|
|
#
|
|
# PUBLIC-VARIABLE defaults to AX_PACKAGE_REQUIRES, and PRIVATE-VARIABLE
|
|
# defaults to AX_PACKAGE_REQUIRES_PRIVATE. Both variables are AC_SUBST-ed
|
|
# by this macro.
|
|
#
|
|
# For example:
|
|
#
|
|
# AX_PKG_CHECK_MODULES([GLIB],[glib-2.0 gio-2.0],[gthread-2.0])
|
|
# AX_PKG_CHECK_MODULES([DBUS],[],[dbus-glib-1 >= 0.98 dbus-1])
|
|
#
|
|
# results in the substitutions:
|
|
#
|
|
# AX_PACKAGE_REQUIRES="glib-2.0 gio-2.0"
|
|
# AX_PACKAGE_REQUIRES_PRIVATE="gthread-2.0 dbus-glib-1 >= 0.98 dbus-1"
|
|
#
|
|
# and can be used with a template pkg-config file (.pc.in) using:
|
|
#
|
|
# Requires: @AX_PACKAGE_REQUIRES@
|
|
# Requires.private: @AX_PACKAGE_REQUIRES_PRIVATE@
