Re: [rdiff-backup-users] build problem on solaris 10, x86

Thanks Roland!

So you think linker flags should be set when building rdiff-backup?  
I'm a total python novice but I was thinking these linker flags would  
have to be set when building python. Anyhow, I'll try out what you're  
suggesting...

OK, well I opened up setup.py and I saw that I could the option "-- 
lflags" so I tried this and low it works a treat. So, here's what you  
do:

build command:
	python setup.py --librsync-dir=/usr/local --lflags="-R /usr/local/ 
lib" build
                
install command:
        sudo python setup.py install --prefix=/usr/local

And now I can happily run /usr/local/bin/rdiff-backup without needing  
to set LD_LIBRARY_PATH or putting a symlink to librsync.so.1 in /usr/ 
lib.

Thanks for you help.

Cheers
Jesse

PS ... By the way, some newlines in your email aren't coming through  
for some reason so I had to guess where you had paragraph breaks, see  
below.
