I think the answer is chmod -R g-w foo.kext but I'm not positive. The usual way is to do a "pbxbuild install" and you'll get something in /tmp with the right permissions.

Right; the "standard" permissions we recommend are 644 for files and 755 for dirs. The owner/group should be root/wheel. Minimally, your kext (all files & dirs) must be owned by root and may not be writable by any user other than root. Obviously, to be read by the kext loading system they need to be readable by root, but should also be readable by non-root users in order for Finder and AppleSystemProfiler to be able to present them in the GUI.

Debugger able to translate physical to virtual
by Francis bouchard 28 May '02

28 May '02

As you probably all know, in remote debugging with gdb, it is impossible to see the memory at a specified physical adress. Is there a way to do the translation with gdb from physical to virtual so I can display the memory ??

Hi everybody, I'm sorry for this off-topic message. I'm a student at University of Rome Tor Vergata, and I'm trying to organize a seminary on MacOs X, focusing on the darwin kernel and the open-source policy. I wrote this message because I'm looking for someone in Rome to speech about the tecnhical aspects of the kernel in comparison with Linux. If anyone can help me please e-mail amadori(a)vitrociset.it or nicholas.amadori(a)stud.uniroma2.it Thank you for your attention Nicholas Amadori _______________________________________________ darwin-kernel mailing list | darwin-kernel(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.

Bottom line, System V shared memory sucks, and always will. On every OS, not just Mac OS X. You should be able to find my POSIX shared memory patch for postgres if you do a net search for Postgresql and Mac OS X, but it's really only a partial fix, since it still limits you to a small number of shared regions (just about twice as much as the kernel System V support). The real fix would be to do something more intelligent than my mapping table... maybe a dynamically resizable table for a quick fix. Anyway, it's out there on the 'net, and should give you a good starting point. Later, David --------------------------------------------------------------------- David A.
