[PPL-devel] PPL for Mac

[Swarat Chaudhuri]

Ah, ok. Just so you know, I tried to compile the test program and it
returned:
ld warning: in /usr/local/lib/libgmpxx.dylib, file is not of required
architecture
ld warning: in /usr/local/lib/libgmp.dylib, file is not of required
architecture
Undefined symbols:
  "___gmpz_clear", referenced from:
      _main in ccUVsrq5.o
      _main in ccUVsrq5.o
  "___gmpz_init_set_str", referenced from:
      _main in ccUVsrq5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

This is a bit strange, as I compiled libgmp from source and it seemed to go
fine. But thanks, I'll post on the libgmp message board and try to find out.

Best,
Swarat
