[rdiff-backup-users] Compile error against librsync 1.0.0.

[Ed Greenberg]

My backup server is Centos 6 and rdiff-backup 1.2.8. and I have my first 
few Centos 6 boxen backing up fine.

Unfortunately, I have a bunch of Centos5 machines that cannot be 
upgraded to Centos6 or 7.   Epel for Centos 5 installed 1.0.5, which 
failed miserably to back up to the 1.2.8 backup server. No surprise 
there.  I'm familiar with the requirement that versions match.

So I am trying to build 1.2.8 on Centos 5.

After installing librsync-devel, rsync-devel, python-devel and, of 
course, gcc, my build fails as follows:

address@hidden rdiff-backup-1.2.8]# python setup.py build

_librsyncmodule.c:63: error: too few arguments to function ‘rs_sig_begin’

address@hidden rdiff-backup-1.2.8]#


Current rev of librsync is 1.0.0.  On the web I found that the constant 
RS_DEFAULT_STRONG_LEN is defined in librsync.h, but that the definition 
is missing in that file in 1.0.0.

Does anybody know how to resolve this?

Thanks,
