install_elphel

基于FPGA的IP camera的开源系统

#!/bin/sh
#
# install_elphel -- install, customize and build elphel camera software 
#       This is an interactive "wizard" that asks questions as it goes.
#
# Overview of installation process:
#       The file elphel_$REVNUM.tar.gz is made available to you.
#       You cd to a suitable directory.
#       I reccomend putting both the elphel_$REVNUM.tar.gz file in this
#       directory as well as the needed linux and axis files.
#       Unpack using:
#               gtar xzvf elphel_$REVNUM.tar.gz
#       which will create a directory elphel_$REVNUM.
#       You cd into that directory, where you will find this script along
#       with a README file and a file named elphelcamera.tar .
#       Run this script:  ./install_elphel
#       You will be prompted for the camera model (313 or 323).
#       You will be prompted for the locations of axis and linux sources
#       (unless they can be found in "..")
#       along with information of where to get them;
#       use a separate window (or...) to get them and then enter where
#       you put them.
#       You will be asked where you want to put the output;
#       the default is to put in ./elphel$MODEL which is usually adequate.
#       You will be asked if you want to build the software now or later;
#       if now, it will be built for you.
#       The README, install_elphel and elphelcamera.tar files will remain
#       and can be used, for example, to do a separate installation for 
#       another camera model.
#       (Only one camera model can be supported per installed directory).
