linux - 构建 lsnes 时出现 "undefined lua_xxxxx"链接错误

Question

在我的 ubuntu 14.xx 中，我尝试编译 lsnes 模拟器以使用来自 aleju/mario-ai 的 mario-ai 脚本。 ，并且我尝试通过谷歌搜索许多解决方案来解决以下问题:

这是控制台的输出:

==================================

一开始，我想，链接器找不到我的lua库。所以我试着用 test.lua 编译我的 main.cpp。

主要.cpp:

#include <stdio.h>
#include <iostream>

//extern "C"
//{
#include <lua.h>
#include <lualib.h>
#include <lauxlib.h>
//} // liblua5.1-c++.a 
lua_State * L;
int main ()
{
     L = lua_open();
     luaL_openlibs(L);
     luaL_dofile(L, "d:\\test.lua");
     return 0;
}

测试.lua:

print("Hello World");

我写一个 MakeFile 来生成可执行文件“main”:

main:main.o
    gcc -o $@ $< -llua5.1 -lstdc++
main.o:
    gcc -c main.cpp
clean:
    -rm *.o

当我添加编译选项“-llua5.1”和“-lstdc++”时它起作用，否则它会抛出与我编译 lsnes 相同的错误

我不熟悉 gcc 和 Makefile。请帮我解决这个问题。

我已经解决了我的问题

解决这个问题的方法就是在名为“options.build”的文件中更改一行。

1. find the line "LUA=lua" in options.build

2. change this line to "LUA=lua5.1"

因为需要的库是5.1，所以如果你想成功构建它，你必须使用“lua5.1”库但是默认配置是“lua”而不是“lua5.1”
