- Create Payload
- Create Installer script
- Packaging
This is a tar ball in which all the installable binaries, libraries, script files, configuration files, etc will be placed in the same file hierarchy of the target board considering the base directory of the tar ball is the installation directory on the target board.
periask@ubuntu:~$ mkdir -vp packaging/Payload mkdir: created directory `packaging mkdir: created directory `packaging/Payload' periask@ubuntu:~$ cd packaging/Payload periask@ubuntu:~/packaging/Payload$ cp --preserve=mode -rl <installables> . periask@ubuntu:~/packaging/Payload$ tar zcf ../Payload.tar.gz . periask@ubuntu:~/packaging/Payload$ cd .. periask@ubuntu:~/packaging$
Create Installer Script:
Copy the below content and create "installer" file in "packaging" directory.
#!/bin/bash # Get the starting point of the tar ball SKIP=`awk '/^__ARCHIVE__/ { print NR + 1; exit 0; }' $0` # Do pre-installation steps here. # Extracting the tar ball Which is appended to this file tail -n "+$SKIP" $0 >/dev/null 2>&1 if [ $? -eq 0 ]; then tail -n +$SKIP $0 | gunzip -c | tar -C / -xvf - else tail +$SKIP $0 | gunzip -c | tar -C / -xvf - fi # Do post-installation steps here. exit 0 __ARCHIVE__
Note: There should not be any space after "__ARCHIVE__" and should be a new line after "__ARCHIVE__".
Packaging:
Concatenate the file "installer" and "Payload.tar.gz" and create the package file.
periask@ubuntu:~/packaging$ cat installer Payload.tar.gz > Package-Version.sh periask@ubuntu:~/packaging$ chmod +x Package-Version.sh
Installer for your package "Package-Version.sh" is ready.
