Qt与Lua | lua文件的放置位置 [英] Qt with Lua | Where to place lua file(s)
问题描述
我已经创建了一个cpp文件,其中的main方法实现了对lua的调用. 编译+执行qt项目时,出现以下错误:
I've created a cpp file with the main method implementing calls to lua. When compiling + executing the qt project I receive the following error:
PANIC:调用Lua API时出现不受保护的错误(试图调用字符串值)
PANIC: unprotected error in call to Lua API (attempt to call a string value)
问题是lua找不到要执行的lua文件(至少我认为是).因此,我将文件复制到了所有调试目录和主目录,但仍然无法正常工作.
The problem is that lua cannot find the lua file to be executed (at least I think it is). So I copied the file to all the debug dirs and the main dir but it still didn't work.
感谢您的帮助!
main.cpp
#include <stdio.h>
extern "C" {
#include "lua.h"
#include "lualib.h"
#include "lauxlib.h"
}
lua_State* L;
int main(int argc, char *argv[])
{
/* initialize Lua */
L = luaL_newstate();
/* load Lua base libraries */
luaL_openlibs(L);
/* load the script */
luaL_loadfile(L, "test.lua");
lua_call(L, 0, 0);
/* cleanup Lua */
lua_close(L);
}
和文件test.lua
and the file test.lua
-- test
print("Hello World")
推荐答案
Qt似乎使用用户目录作为默认路径.
It seems like Qt uses the user's directory as default path.
您可以通过以下方式对此进行验证:(感谢丰富)
You can validate this with: (thanks Rich)
QDir dir(".");
qDebug() << dir.absolutePath();
将lua脚本放入此文件夹时,所有内容都像一个超级按钮.
When putting the lua script into this folder everything works like a charm.
可以使用以下命令设置工作目录:
The working directory can be set with the following command:
QDir::setCurrent()
并与
QCoreApplication::applicationFilePath()
可以将路径设置为exe登录的位置.
The path can be set to where the exe resigns in.
