我正在尝试在 OSX Snow Leopard 上构建 LuaJava，但遇到了链接问题。我已经修改了 OSX 的配置脚本，并确保所有路径都是正确的。我必须更改 luajava.c（第 2795 行）以使 lua_resume 采用两个 LuaState。这使它通过了构建阶段，但链接失败。这就是我得到的：

export MACOSX_DEPLOYMENT_TARGET=10.6; gcc -dynamiclib -all_load -o libluajava-1.1.jnilib src/c/luajava.o /usr/local/lib/liblua.a

我不明白，因为我刚刚为这个系统从 soruce 构建了 lua。有任何想法吗？

我不确定您的设置有什么问题，这是我在 Mac OS X Lion 上成功编译 LuaJava 所做的工作：

下载并编译最新的 Lua 5.1

$ wget http://www.lua.org/ftp/lua-5.1.5.tar.gz
$ tar xzf lua-5.1.5.tar.gz
$ cd lua-5.1.5
$ make -j macosx
$ make install
$ cd ..

下载 LuaJava

$ wget https://github.com/jasonsantos/luajava/zipball/master
$ mv master luajava.zip
$ unzip luajava.zip
$ mv jasonsantos-luajava-32a3fcd/ luajava
$ cd luajava

编辑配置文件

$ diff -u config.old config
