[英]Using Lua with C++
I'm trying to embed lua in ac program, but I'm having problems to compile the code. 我正在尝试将lua嵌入到ac程序中,但是在编译代码时遇到了问题。 I have installed everything lua 5.2 related in synaptic and when tried to compile this:
我已经在突触中安装了与lua 5.2相关的所有内容,并在尝试编译时:
extern "C"{
#include <stdio.h>
#include <string.h>
#include "lua5.2/lua.h"
#include "lua5.2/lauxlib.h"
#include "lua5.2/lualib.h"
}
int main(int argc, char* argv[])
{
lua_State *lua_state;
lua_state = luaL_newstate();
lua_close(lua_state);
}
and compile using 并使用编译
g++ main.cpp -llua
g ++ main.cpp -llua
show the folowing errors 显示以下错误
Could not find -llua
找不到-llua
what do? 做什么?
There are tools you can use to find the proper compiler / linker switches for a library. 您可以使用一些工具来为库找到合适的编译器/链接器开关。
In particular, with a proper installation of the lua5.2 libraries you can use 特别是,通过正确安装lua5.2库,您可以使用
pkg-config -libs lua5.2
On my system it outputs 在我的系统上它输出
-llua5.2
Use this, or the output of pkg-config (backticked) as your linkers argument. 使用它,或将pkg-config的输出(反引号)用作链接器参数。
Of course, pkg-config can also tell you the -CFLAGS for the package with 当然,pkg-config也可以告诉您-CFLAGS的软件包
pkg-config --cflags lua5.2
The man page is quite readable. 手册页可读性强。
