[waffle] Building Waffle with XCode?

[Jeff Bland]

Surprised it loaded in Xcode 3.1 since the project format is 3.2-compatable.

Apparently the GCC 4.2 that shipped with Xcode doesn't support thread local
storage on x86_64. You could try deleting the __thread bit on that line as
a temporary workaround, but it should work in a recent Xcode w/ clang. When
you tried the current Xcode, did you use clang, and did you get a similar
error?

I noticed an unrelated link error as well, the Xcode project is missing
src/waffle/core/wcore_attrib_list.c, I'll send in a patch for that.
