[llvm-commits] llvm-gcc build error on leopard

[Chris Lattner]

I'm seeing this link error building llvm-gcc on leopard:

ake[2]: *** [cc1objplus-dummy] Error 1
Undefined symbols:
   "_ncpu_available", referenced from:
       _ggc_min_heapsize_heuristic in libbackend.a(ggc-common.o)

I also see:

../../src/gcc/ggc-common.c: In function ‘ggc_min_heapsize_heuristic’:
../../src/gcc/ggc-common.c:749: warning: implicit declaration of  
function ‘ncpu_available’
gcc

Is this in a special library or unavailable on leopard?  If so, use of  
this function should be predicated on the build host having it somehow.
