我有以下文件：
hello.h
#ifndef HELLO_H
#define HELLO_H
class Hello {
private:
int _number;
public:
Hello(int number);
void printHello(void) const;
};
#endif
HELLO.CPP
#include "hello.h"
#include <iostream>
Hello::Hello(int number)
: _number(number) {
}
void Hello::printHello(void) const {
std::cout << "Hello, " << this->_number << std::endl;
}
hello.swg
%module hello
%{
#include "hello.h"
%}
%include "hello.h"
的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。这导致hello.dll。
打开lua解释器，我输入：
hello=require('hello')
inst=hello.Hello(23)
inst:printHello()
正如我所希望的那样打印出“Hello，23”，因此模块加载似乎正常工作。
然而，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lua.exe崩溃。当我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：以下是使用问题行运行test.lua时，depends.exe生成的输出，通过lua.exe

答案 0 :(得分：0)
以下是一些尝试：
您的cmake有FIND_PACKAGE(Lua51)，这可能会导致hello.dll与Lua 5.1链接，而您正在运行Lua 5.2。
通过visual studio运行lua test.lua。您可以通过几种方式实现这一点，其中一种方法是运行lua test.lua并使脚本暂停，等待输入;在等待输入时，你运行visual studio并附加到lua进程;然后你按下lua控制台中的enter键，这样脚本就会继续;您可能知道故障发生的位置（发布文件/行＃）。
我怀疑这个问题是一个系统DLL，更有可能的是hello.DLL是用不兼容的设置构建的，比如单线程而不是多线程。检查链接到的Lua是否为mingw，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。在制作Lua时检查编译和构建命令是什么（可能为make设置详细标记 - 您发布的内容只显示正在运行g ++的状态消息，而不是显示包含路径的命令行参数等等），并找到如何使用cmake。
原则上你应该能够复制Lua makefile并用hello.lib和co替换列出lua51.lib等的几行。
