[cfe-dev] [LLVMdev] [Reminder] LLVM 3.4 Release Branching

[Alexander Potapenko]

Jack,

Where do the "-isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk
-mmacosx-version-min=10.8" flags come from? I don't see them in your
CMake invocation - perhaps they're added via $CC or $CFLAGS? Is this
being done on purpose?

I can add a CMake step checking whether the current CFLAGS/LDFLAGS
allow to build an iossim binary, and skip building the iossim runtime
if that's impossible.
But in that case your compiler won't be able to build the iossim runtime at all.
