c++ - 使用 SWIG 和 MinGW 创建的 Lua 模块，导致解释器在退出时崩溃

Question

我有以下文件:

你好.h

#ifndef HELLO_H
#define HELLO_H

class Hello {
    private:
        int _number;

    public:
        Hello(int number);
        void printHello(void) const;
};

#endif

你好.cpp

#include "hello.h"
#include <iostream>

Hello::Hello(int number)
    : _number(number) {
}

void Hello::printHello(void) const {
    std::cout << "Hello, " << this->_number << std::endl;
}

你好.swg

%module hello
%{
    #include "hello.h"
%}
%include "hello.h"

CMakeLists.txt

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
FIND_PACKAGE(Lua51)
INCLUDE_DIRECTORIES(${LUA_INCLUDE_DIR})
ADD_LIBRARY(
    "hello"
    SHARED
    "hello_wrap.cxx"
    "hello.cpp"
)
TARGET_LINK_LIBRARIES(hello "${LUA_LIBRARIES}")
SET_TARGET_PROPERTIES(hello PROPERTIES PREFIX "")

我使用 SWIG 生成 hello_wrap.cxx，然后通过 CMake 创建 MinGW Makefile，并构建它们。这会生成 hello.dll。

打开 lua 解释器，我输入:

hello=require('hello')
inst=hello.Hello(23)
inst:printHello()

正如预期的那样打印出“Hello, 23”，因此模块加载似乎工作正常。

但是，当我这样做时:

os.exit()

我收到以下错误:

"This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information."

随后是 lua.exe 崩溃。当我只是这样做时也会发生这种情况:

hello=require('hello')
os.exit()

有没有人对我如何解决这个问题有任何想法？

提前致谢。

编辑:以下是 depends.exe 通过 lua.exe 运行带有问题行的 test.lua 时产生的输出

Answer 1

这里有一些尝试:

1. 您的 cmake 有 FIND_PACKAGE(Lua51)，这可能导致 hello.dll 链接到 Lua 5.1，而您运行的是 Lua 5.2。

2. 通过 visual studio 运行 lua test.lua。您可以通过几种方式做到这一点，其中一种是运行 lua test.lua 并使脚本暂停，等待输入；在等待输入时运行 visual studio 并附加到 lua 进程；然后在 lua 控制台中按 enter 以便脚本继续运行；您可能会知道故障发生在哪里(发布文件/行#)。

3. 我怀疑问题出在系统 DLL 上，更有可能是 hello.DLL 是使用不兼容的设置构建的，例如单线程而不是多线程。检查您链接到的 Lua 是否是用于 mingw 的，使用相同的编译器设置构建。make 中最重要的信息是构建和链接的最终命令是什么。当你制作 Lua 时检查编译和构建命令是什么(也许为 make 设置详细标志 - 你发布的只是显示 g++ 正在运行的状态消息，而不是给它的命令行参数显示包含路径等)，并了解如何使用 cmake 获取这些内容。

4. 原则上，您应该能够复制 Lua makefile 并将列出 lua51.lib 等的几行替换为 hello.lib 和 co。
