site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Hi, I'm having a few problems with a piece of hardware that's "grabbed" by a MacOS driver (an USB modem), but that driver doesn't correctly access the card. So I'm now trying to setup a simple KEXT that I can configure as driver for that particular vendor/product to prevent the standard MacOS driver from getting it, and I hope that the card can be accessed with my userspace "driver" then that I use for some other cards. Going through the developer website I came up with the HelloKExt example code. I copied that, adjusted the names, and now I'm trying to compile it. I don't use XCode, for a number of reasons, and I've figured out a number of options that I need to set (or remove, as they would trigger warnings on system header bugs, which doesn't work well with -Werror...) to make it compile, but I still get a ton of undefined symbols on linking. Currently, the compiler is invoked like this: This does not produce errors, but of course something could still be wrong. The linking is done like this ATM:

From the looks of it, it seems that I need to link with something else, but so far I've been unable to find out what is missing. If I add -static to the linker call, I only get one error about not being able to find the file for -lcrt0.o, but I assume that it just doesn't get to the undefined symbols :-) If I set up X-Code on one of the boxes, can I see the options it uses to compile something and other stuff that it might add into the code before compiling? Thanks for any hints, Christian
