Is there an existing config handler which would be able to automatically add the necessary properties to the registry, or will I need to write a separate configd plugin? Now that the drive is running, I've seen some new configd syslog err msgs regarding "wireless configure"... -- Shaun Wexler MacFOH http://www.macfoh.com This email sent to site_archiver(a)lists.apple.com

This is a privileged call on OS X Intel because the Mach task pretty much gives you full control over it, which is why it fails on things like setuid binaries and other processes which aren't owned by the caller. This is probably a sign of a program which should be fixed not to call task_for_pid() on everything but it'd also be nice if someone made the kernel message more informative. For a root process, this is the message that gets printed when the program indicated attempts to call task_for_pid() on an already dead or non-existant process.

In the meantime, you can find them here. I strongly recommend that you start with these samples rather than trying to work with one of the production file systems. The samples were written specifically as sample code, whereas the production file systems have accumulated cruft over decades of development. At 13:46 +0300 3/12/06, Kirill Kuvaldin wrote: Well, we do have makefiles (the kernel builds that way, for example), but not all projects use them. "msdosfs" has an old Project Builder project. What you should do about that depends on your circumstances. Options include: o Most Darwin projects will build using DarwinBuild, but I haven't tried this myself with "msdosfs". o If you open the project with Xcode, it will do a reasonable job of converting the project to a more modern format (don't forget to upgrade the targets to the native format). You then only have to worry about the semi-private header files that aren't included in the standard developer tools (-: o Alternatively, just copy the source files over to a modern Xcode project (like the one that ships inside MFSLives) and start from there. o Once you have something building in Xcode, you can build it from the command line using "xcodebuild". o Alternatively, it's easy to look at the Xcode build log to see the magic that you have to do to build a KEXT using a makefile. It really depends on your final goal. If you're looking for something makefile-based because that's what your build systems uses on other platforms, it's worth the effort setting up a makefile. If you're just experimenting, do it in Xcode: you'll get further faster. This email sent to site_archiver(a)lists.apple.com
