It's easy to checkout via CVS. I also tweaked the Makefile to build a universal binary of it - if you're interested in trying it out, I'll mail you a copy. It looks like you're likely to stress test it more than i will. I've even been using the version that went out today on some of my own machines for awhile now without encountering this error... _______________________________________________ Do not post admin requests to the list.

Under Linux, yes. I think Sarang was asking about under Darwin (or Mac OS X) though, which is neither currently possible nor AIUI simple to implement. Solaris, FreeBSD and Linux all use the same binary format called ELF, so "all" you have to do on e.g. Solaris to get a Linux binary to run is intercept library calls and make sure the Linux version of the call is executed. On Darwin with the Mach-O binary format, there's a lot more work to do. I remember a thread on this somewhere recently where someone suggested it might be possible to achieve using a process similar to the CFM runner for PEF binaries, sorry I can't remember the attribution but Uncle Google probably can.

I use a proprietary Linux application at work, and it would be great if we could simply run it on Macs at home, or on any new MacBooks our lab might acquire. :) (No, the software vendor isn't willing to give out the source code or recompile anything as of yet.) I'm willing to put some work into it, but my expertise is at the system administrator and scientific computing level, so I don't know if this is within my grasp. I imagine this would be useful to lots of people in the scientific community... I realize VMWare and dual-booting options are on their way, but a compatibility layer would be ideal for many of us.

I came across this because it was reported on the fink-users list; "fink selfupdate-rsync" doesn't work any more. Then I did some tests myself and confirmed. One more point: I have one machine where the security update was not yet done and when I rsync --delete between this machine and an updated one (both ways), the delete works on the side with the old rsync, but not on the one with the new rsync.
