Is it possible to archive (in SVN, for example) a complete package that allows LTIB to rebuild from “source” with a single command using the libraries that were archived at the time of archive?

 

The situation is this. The developers will configure LTIB (kernel, RFS …) and download all packages needed. At some point, they will check this into an archive so that the Configuration Management Organization (CMO) can check it out and build it.

 

The CMO build will have no access to the internet and the personnel, who are not familiar with LTIB, will want to invoke a script that does everything – even setting up /opt/freecale -- with no interaction.

 

I have been able to do some this, such as setting up a local package pool and using preconfigure, but I cannot accomplish the whole thing without some manual interaction and/or retaining a significant amount of the build by-products.

 

Ideally, I would like to save nothing more than the original source (LTIB and packages) and small number of configuration files. Then have a script that takes these and performs the complete build.

Obviously you only want to save the LTIB source (and local package pool with appropriate configuration in .ltibrc to point to it) in SVN and have the CMO machine check it out and build "from scratch".  Of course you have to assume that the CMO build machine has all the necessary host packages to complete the build (i.e. build-essentials, etc) as well as grants the "build user" appropriate sudo permissions.

Given that you could write a script that automates the process via:

1) check out latest version of the LTIB source directory (that contains the local package pool that has copies of everything the build pulls from the global package pool)
2) rm -rf /opt/freescale
3) rm -rf rpm
4) sudo rm -rf rootfs*
5) rm -f .host_warning*
6) rm -f .tc_*
7) ./ltib -b --preconfig config/platform/<platform>/<defconfig>

Where "<platform>" is the platform directory and "<defconfig>" is the default LTIB configuration file.
Note the ".tc_*" is the trigger file telling LTIB to skip installing the toolchain package and ".host_warning*" is the trigger file telling LTIB to skip building its host packages - hence removing them forces LTIB to repeat those steps.

This should pretty much build LTIB completely from scratch...
