Someone mentioned to me that the bleeding_edge branch as i64 support, so I tried compiling that with the arch=x64 flag, but no such luck. Different error though: [3][0] ~/scratch/v8-bleeding $ scons arch=x64 scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... g++ -o obj/release/platform-macos.o -c -Wall -Werror -W -Wno-unused- parameter -pedantic -fno-strict-aliasing -O3 -fomit-frame-pointer - fdata-sections -ffunction-sections -ansi -mmacosx-version-min=10.4 - m64 -fno-rtti -fno-exceptions -Wall -Werror -W -Wno-unused-parameter - pedantic -fno-strict-aliasing -O3 -fomit-frame-pointer -fdata-sections -ffunction-sections -ansi -mmacosx-version-min=10.4 -m64 - DV8_TARGET_ARCH_X64 -DENABLE_LOGGING_AND_PROFILING -Isrc src/platform- macos.cc In file included from src/platform-macos.cc:31: /usr/include/ucontext.h:42:2: error: #error ucontext routines are deprecated, and require _XOPEN_SOURCE to be defined scons: *** [obj/release/platform-macos.o] Error 1 scons: building terminated because of errors.

[v8-users] Re: Problems compiling on Snow Leopard / gcc 4.2.1
Tom, Can you please try with bleeding_edge revision 2489? This should make sure that the gcc flags and the target architecture are consistent. I do not have a Snow Leopard machine to test on currently, but this change should fix the confusion of gcc building for a 64-bit target when we are generating ia32 code in the JIT. Thanks, -Ivan P.S. Also note that the x64 build is certainly not at a state where you should be testing it yet unless of course you want to commit fixes to it.
