# This script allows you to install Asterisk into a subdirectory of
|

|
# your source distribution and run it from there.
|
||
|
|
#
|
||
|
|
# Example usage:
|
||
|
|
#
|
||
|
|
# contrib/scripts/live_ast conf-file # optionally. and now edit live/live.conf
|
||
|
|
# # edit live/live.conf
|
||
|
|
# contrib/scripts/live_ast configure
|
||
|
|
# make
|
||
|
|
# contrib/scripts/live_ast install
|
||
|
|
# contrib/scripts/live_ast samples
|
||
|
|
# contrib/scripts/live_ast run
|
||
|
|
# contrib/scripts/live_ast run -r
|
||
|
|
# ./live/asterisk -r # Same as run -r
|
||
|
|
#
|
||
|
|
# A standard debugging cycle of a code in a module:
|
||
|
|
#
|
||
|
|
# # edit apps/app_skel.c
|
||
|
|
# contrib/scripts/live_ast install
|
||
|
|
# contrib/scripts/live_ast run -r
|
||
|
|
# # and in the CLI:
|
||
|
|
# module unload app_skel.so
|
||
|
|
# module load app_skel.so
|
||
|
|
#
|
||
|
|
# If you have external scripts that run asterisk, use the script
|
||
|
|
# live/asterisk that is generated by the 'samples' command. In this case you
|
||
|
|
# should probably also rem-out the line 'astvarrundir' and maybe also
|

|
|
# 'astetcdir' in live/etc/asterisk.conf .

# LIVE_AST_LIBPRI_PATH:
|
||
|
|
# To use a libpri SVN directory (without running 'make install': make include
|
||
|
|
# a symlink to the current directory:
|
||
|
|
# ln -s . /path/to/checkout/of/libpri/include
|
||
|
|
# Be sure to run there 'make'. Then set in live.conf:
|
||
|
|
#LIVE_AST_LIBPRI_PATH="/path/to/checkout/of/libpri"
|
||
|
|
#
|
||
|
|
# LIVE_AST_ZAPTEL_PATH:
|
||
|
|
# Likewise, the same trick can be used to build vs. a local copy of zaptel:
|
||
|
|
# ln -s /path/to/checkout/of/zaptel/include .
|
||
|
|
# ln -s /path/to/checkout/of/zaptel/zaptel .

||
|
|
#LIVE_AST_DAHDITOOLS_PATH="/path/to/dahdi-tools/dir"
|
||
|
|
#
|
||
|
|
# Another alternative for Zaptel is to use the live_zap script included
|
||
|
|
# with the Zaptel distribution. The following should work after you used
|
||
|
|
# './live_zap install' or even with a copy generated with
|
||
|
|
# './live_zap rsync' . '/apth/to/zaptel' is the directory containing the

|

#

# LIVE_AST_BRISTUFFED_LIBPRI
|
||
|
|
# A hack to use the second, "bristuffed" copy of libpri that exists
|
||
|
|
# e.g. in the Debian libpri-dev package. If set to a non-empty value,
|
||

|
# is run.

# LIVE_AST_FOR_SYSTEM
|
||
|
|
# When generating asterisk.conf, use most components from the installed
|
||
|
|
# system. Also provide a sane var-run directory for those of us who want
|
||
|
|
# to do the right thing and run asterisk as non-root.
