get netinet headers from iPhoneSimulator SDK, not iPhoneOS SDK #494

Closed dicej closed 8 years ago

dicej commented 8 years ago

As of SDK 9.2 at least, the headers we need are not part of the device SDK, only the simulator SDK.

Hmm... I'm not seeing the same files:

$ find /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform -name netinet -type d
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/netinet

The files we're interested in are e.g. ip_icmp.h, icmp6.h, etc. For example, on my machine /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include/netinet/ip_icmp.h exists, whereas /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/netinet/ip_icmp.h does not, hence the PR.

ah, gotcha. Seems like this has been going on for a while:

According to http://blog.slaunchaman.com/2010/02/13/using-apples-simpleping-on-iphone-os/, an apple engineer confirmed that symlinking those files into the iPhoneOS SDK was the way to go. (shivers)

This seems like a good alternative to mucking with user's machines.
