Re: Build 10.5 kext on 10.9

Jeff, I have used Xcode 5.1 running on Mavericks 10.9.2 to build kexts that run under 10.7. To accomplish this, I had to add the MacOSX10.7.sdk (which I copied from Xcode 4.6.3 running on Lion 10.7.5) to Xcode's SDK folder: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/ Perhaps adding the 10.5 SDK (and pointing the appropriate targets to it) will do the trick for you.

Thanks for the reply. I was really hoping to avoid hacking Xcode, but might resort to that if necessary. The two-system build setup is a fairly big pain, so I'd like to get this working. Were you having build (compile/link) or runtime issues with the kext that caused you to move to this? I actually thought I had a breakthrough.

Why? Unless you get the same IP address when you re-enable the interface, the server won’t know what to do with the FIN anyway. Andreas’s description is correct. I’d describe this as a bug in Linux. --Amanda I just thought FIN's are handled the same way as any other data. Anyway I'm fine with that, just wanted to get an idea what's right here. So thx all. _______________________________________________ Do not post admin requests to the list. They will be ignored.
