How to build rdiff-backup from a git clone.

Anyone know how to build rdiff-backup from a git clone?

librsync is in non-standard location but it seems that the build is just broken.

I tried python setup.py install but that fails when it can't find rdiff_backup. setup.py is in dist/ and rdiff_backup is at the same level as dist/.

I found out the rdiff-backup is not compatible with the latest librsync.

You can install librsync 0.9.7 from sourceforge and use it with rdiff-backup, unless there were features you specifically need in librsync 2.x

As far as I know there are no features in 2.x that I need but I found that I just had to patch one file so things would compile.

The call to rs_sig_begin need to use the new three parameter form.

rdiff_backup/_librsyncmodule.c

Code:

sm->sig_job = rs_sig_begin((size_t)blocklen,(size_t)8, RS_MD4_SIG_MAGIC);

Now it all works.
I have always liked rsync so I like that rdiff_backup makes use of the technology. Binary diff is a nice thing.
