Use openpctv to learn how to install and generate an opkg package

OpenPCTV-more comprehensive TV functions for your HTPC

I learned from linuxtoy that openPCTV is packaged with opkg.

Obtain source code:git clone git://git.code.sf.net/p/openpctv/code openpctv-code

After the download, we found that it was not based on buildroot. Instead, we used the script and makefile methods to achieve automated compilation. we can select the cubieboard board to compile and create rootfs and iso, and roughly check the script, suitable for learning.

Currently, you can refer to opkg for openembedded and buildroot, that is, openPCTV.

Script/installdev script

Use -- offline-root to specify the target root directory of rootfs.

First create the var/lib/opkg/info directory, similar to the archlinux pacman installation requires the establishment of var/lib/pacman

$ ROOT/$ TOOLCHAIN/bin/opkg -- offline-root $ ROOT/$ TOOLCHAIN \ install $ PACKAGE> & $ VERBOSE_OUT need to create a directory first

mkdir -p $ROOT/$TOOLCHAIN/var/lib/opkg/info/STAMP=$ROOT/$TOOLCHAIN/var/lib/opkg/info/$1.control

The index file is used to generate the opkg repository index file, which is the same as the script in OE.

You can use the opkg-make-index parameter description to generate

#!/bin/sh. config/options$SCRIPTS/installdev opkg-utils[ "$VERBOSE" = yes ] && V="-v"opkg-make-index $V -l $PKGROOT/Packages.filelist -p $PKGROOT/Packages $PKGROOT

The packagedev file is mainly used to generate the opkg package.

First, call to parse some meta information in the package directory, generate the control file through add_control, and finally use opkg-build-O-o root-g root $ INSTALL $ DEVPKGROOT> & $ VERBOSE_OUT

Create the target package file. "-O" indicates that the opk suffix is used. "-o" indicates that "-O" indicates that "-g" uses user permissions and is passed to tar compression for parameter usage,

There is a funtions file in the configs/directory, which is a common function library. For example, functions such as get_meta can view the code in it.

Build/build. host/toolchain/bin/directory master native tools

After the opkg-build notification is used to create files such as contol and postinstall, compress the files to generate packages such as opk and ipk.

The specific process mainly refers to the debian packaging system, but it is simpler than debian.

Some tools for the http://git.yoctoproject.org/cgit/cgit.cgi/opkg-utils/ yocto project are very helpful for opkg Packaging
