svn_client_status3 causing access violation; what am I doing wrong?
Hey everbody,
I'm trying to do something pretty simple with libsvn; just pass in the
name of a file which is under source control, and retrieve the status.
Unfortunately, my call to svn_client_status3 is just causing an access
violation with no useful error status. Any idea what I'm doing wrong?
Thanks; source follows.

Thanks, turns out all I needed to add was apr_initialize() and it worked
perfectly.
Cheers,

I think you miss some essential initializations of the APR and Subversion
libraries.
You could look at
http://svn.collab.net/repos/svn/trunk/tools/examples/minimal_client.c
to see what a minimal client could do to initialize the libraries properly.
(The example is somewhat outdated; you get a few deprecation warnings when
you use it on 1.6.0; but our compatibility guarantees promise that this
should work until 2.0)
In SharpSvn I use the following methods for global initialization:
apr_initialize()
svn_dso_initialize()
svn_utf_initialize()
svn_fs_initialize()
(SharpSvn doesn't initialize like a commandline tool, so I can't use
svn_cmdline_*()).
Thanks,
