To start the git-annex webapp, run the git-annex-webapp script in this
directory.
To enter an environment with git-annex in PATH, use runshell
This should work on any Linux system of the appropriate architecture.
More or less. There are no external dependencies, except for glibc.
Any recent-ish version of glibc should work (2.13 is ok; so is 2.11).
How it works: This directory contains a lot of libraries and programs
that git-annex needs. But it's not a chroot. Instead, runshell sets
PATH and LD_LIBRARY_PATH to point to the stuff in this directory.
The glibc libs are not included. Instead, it runs with the host system's
glibc. We trust that glibc's excellent backwards and forward compatability
is good enough to run binaries that were linked for a newer or older
version. Of course, this could fail. Particularly if the binaries try to
use some new glibc feature. But hopefully not.
Why not bundle glibc too? I've not gotten it to work! The host system's
ld-linux.so will be used for sure, as that's hardcoded into the binaries.
When I tried including libraries from glibc in here, everything segfaulted.
