Build script to create extension

[bmarkus]

This is my actual build script used to create libidn extension. While extensions may require modification of the script it can be a good startup.

According to the new rules it creates .tcz only using quashfs. There are four extensions created:

1) base - this contains files needed to use the program
2) dev - additional files required to compile other programs depending on this
3) doc - doc files
4) locale - language files

Of course depending on the program certain extensions are not necessary to create, except base.

Looks like a nice generalized approach.  I think I'll use this as a template in the future.

In general, I've found installing to temp destinations problematic.

Could you be more specific?

Links in the extension can end up pointing to the temp destination. Using touch /tmp/mark before installing, and finding with -newer /tmp/mark ensures all the links will be where you want them.

To be precise the problem is not /tmp but installing to any location different than final. True, but this is just a minority of sources. Anyhow, you must check the result always and adjust the scipt to the given case.

All of my posted extensions were compiled with a kind of this script, never used mark.

"temp" meaning "temporary" ...not the /tmp directory     

[Kingdomcome]

many packages obey the "DESTDIR=" flag passed on the "make install" line which makes installing to a temp location for packaging purposes very easy as noted in the wiki.  for the packages that do not, the "touch /tmp/mark" method has worked well for me.
