What is the proper place holder for uint64_t in gcc 4.4. I tried printf("%lld", uint64_t_var); and printf("%llu", uint64_t_var); Neither worked. /home/xtong/coremu-0.1.2/qemu/qemu-ejit.c:103:4: warning: format ‘%llu’ expects argument of type ‘long long unsigned int’, but argument 3 has type ‘uint64_t’ [-Wformat] Thanks Xin
