I'm building the devel trunk on a Mac, using a vanilla configure line: ./configure --prefix=foo. When I try to compile, I get this error:
undefined symbols for architecture x86_64:
"___builtin_expect", referenced from:
_main.omp_fn.0 in otfprofile-otfprofile.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
I believe this comes from your VT code. Can you take a look?
