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.

as the solaris sharedlib faq tells:Q. Why should I use -R when linking programs?
A. The -R option to the linker allows you to specify directories (one
  per occurence or -R) where the program being linked should look for
  its shared libraries when it is run. It should be used whenever a
program requires libraries stored in directories other than /usr/ lib,
  so that the program will find all the libraries it needs.

  On a properly configured system, all programs have been linked with
  -R if they need libraries from elsewhere than /usr/lib, and
  LD_LIBRARY_PATH need not be used.
Instead of using the -R option, the same effect can be achieved by setting the LD_RUN_PATH variable at link time. If both LD_RUN_PATH and -R are used, -R supersedes.so - you need to have shared-libs linked with the appropriate run-path.the problem is: how to tell this to rdiff- backup setup.py ?

in setup.py there seems to be support for adding linker flags:if os.name == 'posix':

LIBRSYNC_DIR = os.environ.get('LIBRSYNC_DIR', '') LFLAGS = os.environ.get('LFLAGS', [])

        LIBS = os.environ.get('LIBS', [])

but when trying to set "export LFLAGS="-R /usr/local/lib" build fails:

export LFLAGS="-R /usr/local/lib"

host:/tmp/rdiff-backup-1.1.5 # ./setup.py build

Traceback (most recent call last):

  File "./setup.py", line 36, in ?

    lflags_arg = LFLAGS + LIBS

TypeError: cannot concatenate 'str' and 'list' objects

you can probably try setting:

extra_link_args="-R /usr/local/lib"

  in setup.py

this _may_ work (don`t have solaris around and cannot try here)

Thanks Roland, and Andrew
As I said, I can get it working if I add /usr/local/lib to LD_LIBRARY_PATH, but it strikes me that either Python or rdiff- backup should store the location of librsync that I gave it when I ran setup.py.
Unless I write a wrapper script (urgh) to set LD_LIBRARY_PATH, then calling rdiff-backup remotely will fail due to it not finding librsync. So for now I have symlinked /usr/lib/ librsync.so.1 -> /usr/ local/lib/librsync.so.1 (urgh again).
Perhaps I could add the LD_LIBRARY_PATH setting into the rdiff- backup python script? Or is there a way to build it so that python knows to look in /usr/local/lib for libraries?
Cheers
Jesse
