lua_open returns null using luaJIT

问题:

Using the recent luaJIT lua_open returns null. This does not happen with the regular lua library.

lua_State *L = lua_open();
std::cout << L << std::endl;

Output: 0x0

How can I get luaJIT to work?

SSCCE:

#include <iostream>
#include <luajit-2.0/lua.hpp>
//linked library: libluajit-5.1.a

int main(int argc, const char * argv[])
{
    lua_State *L = luaL_newstate(); // lua_open();
    std::cout << L << std::endl; // 0x0
}

Additional information: Built on OSX 10.9 from source (tried both 2.0.2 and from git) with make and make install. Using compiler:

$ cc --version
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix

(Using the luajit command line application luajit works fine, a test script gets executed without errors.)

回答1:

Apparently, x64 Mac applications need special handling; see http://luajit.org/install.html.

If you're building a 64 bit application on OSX which links directly or indirectly against LuaJIT, you need to link your main executable with these flags:

-pagezero_size 10000 -image_base 100000000
