[Opensync-users] amd64 and opensync

[Jason S. <jsi...@gm...>]

Has anyone tried it on amd64 OS?  I am running gentoo 64bit and
opensync failes to compile.  Here is the error that I get.

 gcc -DHAVE_CONFIG_H -I. -I. -I.. -pthread -I/usr/include/glib-2.0

Someone tried this several days ago, but his compiler did not complain.
so his opensync crashed of course.

The problem is that im casting between (void *) and (int) which works on
32 bit but will fail on 64 bit of course due to the size differences.

Is there any way around this, besides using temp variables?

Stefan Behlert sugested to first cast to (intptr_t) which is in
inttypes.h
http://sourceforge.net/mailarchive/message.php?msg_id=12671515
This works.

I found the wrong cast that crashed opensync:

After changing this i'm able to sync a evo2 with the file system.
osyncstress with two file-syncs gives random crashes and i'm still looking for a way to get
a backtrace in gdb.
