tce-find enclosed
« on: September 13, 2018, 09:49:43 AM »

Good morning everyone!
I've been working on piCore for the past week (head still banging against the wall!) so I decided to take a look at the 10beta to see if the problems were corrected in a newer firmware and not thinking, I was "shocked" (lol) to see extensions missing from the 10.x repo so it forced me to throw together a script to help tce-load out a bit.
Code: [Select]
#!/bin/sh
. /etc/init.d/tc-functions
clear


#=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=#
#  This script is an EXTENSION to the existing tce-load functionality. This   #
#  app basically gives us the ability to back-port extensions which are not   #
#  yet available in the BETA repository.  The following settings allow us to  #
#  control how far back in history we want to allow this script to access as  #
#  well as whether or not we want to utilize the current beta repo as well.   #
#  This script ASSUMES tce-load [-wi] as its intended arguments               #
#=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=#
min_repo=5                      # Go back UP TO 5.x (incrementing NEW->OLD)   #
max_repo=                       # Leave empty to use the CURRENT version      #
#=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=#

Mind you, it doesn't do miracles, but it allows you to find an extension in history (older repo versions) within the same armv6/armv7 platform and if all files and dependencies are located, install them accordingly.
Example:
tce-find php7
Finds the extension PHP7 in repo v9.x, many of its dependencies in v10.x and so on.  Since all of them are found, it installs them into the system as if it were done by tce-load -wi php7
