Hi,
With help from Wei Dai here's is the workaround to build cryptopp
5.5.2 in gcc 4.0.1 for arch x86_64 in Mac Leopard
1) Modify config.h line 134 from :
#if defined(__GNUC__) && !defined(__INTEL_COMPILER)
to
#if 0
2) Modify integer.cpp line 104 from:
#if !defined(CRYPTOPP_NATIVE_DWORD_AVAILABLE) || defined(__x86_64__)
to
#if 0
Thanks,
Suresh
