SandboxMirror.kext fails to compile on macOS 10.12.4 with XCode 8.1 and up about sandboxmirror HOT 6 CLOSED

I just had no problem building on macOS 10.12.4 with XCode 8.0 (8A218a). Let me try again with later versions and see what happens. It's possible they're at fault here.

I've confirmed your report. I installed XCode 8.3.2 (8E2002) over my previous copy of XCode 8.0, and I now get exactly the same error as you using xcodebuild (from the command line).

It will take me a while to figure out how to work around this. In the meantime you could try installing XCode 8.0 on your system and using that. You'll need to install it under a different name (or in a different directory). But once you have two versions of XCode installed, you can use xcode-select to choose which is active.

thx, i'll try.

By trial and error, I've found out that XCode 8.0 is the last (most recent) version of XCode that works properly to compile SandboxMirror.kext. I'll look for a way to work around this, but (as I said) that may take a while.

In the meantime you should use XCode 8.0 to compile SandboxMirror.kext on macOS 10.12.

This was suprisingly easy to fix. It turns out that as of XCode 8.1, Apple renumbered the "mpo_reservedNN" members of "struct mac_policy_ops" in the macOS 10.12 SDK's mac_policy.h. Fortunately Apple increments MAC_POLICY_OPS_VERSION whenever it changes this structure. So we can check its value to see what kind of mpo_reservedNN numbering to expect.

Please download the current master branch and try compiling it with XCode 8.3.2.

As best I can tell, this is fixed.
