MinGW C ++使用向量退出值127 [英] MinGW C++ using vector exit value 127

问题描述

我在C ++中使用向量时遇到问题.我正在Windows + NetBeans上使用MinGW.

I have a problem using vector in C++. I'm working with MinGW on Windows + NetBeans.

以下代码:

#include <vector>
using namespace std;
int main(int argc, char** argv){
  vector<int> vec;
  return 0;
}

它编译时没有任何错误，但是运行时总是失败，退出值为-1.073.741.511或退出值为127(这意味着ERROR_PROC_NOT_FOUND).

It compiles without any errors, but when run it always fails with exit value -1.073.741.511 or exit value 127 (that means ERROR_PROC_NOT_FOUND).

直接启动exe会显示错误消息，例如:

Starting the exe directly shows up with an error message like:

entrypoint '__gx_personality_v0' not fount in 'libstdc++-6.dll'.

我已经尝试过-lstdc++和

#include <cstdlib>

那是什么问题，我该如何解决?

So what's the problem and how do I solve it?

Netbeans输出:

Netbeans output:

"/C/MinGW/msys/1.0/bin/make.exe" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
make.exe[1]: Entering directory `/c/Users/Josch/CppApplication_1'
"/C/MinGW/msys/1.0/bin/make.exe"  -f nbproject/Makefile-Debug.mk dist/Debug/MinGW1-Windows/cppapplication_1.exe
make.exe[2]: Entering directory `/c/Users/Josch/CppApplication_1'
mkdir -p build/Debug/MinGW1-Windows

mkdir -p dist/Debug/MinGW1-Windows
g++     -o dist/Debug/MinGW1-Windows/cppapplication_1 build/Debug/MinGW1-Windows/main.o 
make.exe[2]: Leaving directory `/c/Users/Josch/CppApplication_1'
make.exe[1]: Leaving directory `/c/Users/Josch/CppApplication_1'

BUILD SUCCESSFUL (total time: 4s)

当然main应该返回int-修复该问题并使用命名空间std添加；

Of course main should return int - fixed that and added using namespace std;

推荐答案

好的，我找到了一个解决方案.

Okay I found a solution.

问题是MiKTeX的安装已添加到PATH变量中.因此Windows链接到libstdc++-6.dll的其他版本.

The problem was an installation of MiKTeX that was added to the PATH variable. So Windows linked to a different version of libstdc++-6.dll.

最后，我找到了两种解决方案:

Finally I found two solutions:

1. 使用-static-libstdc++进行编译，以避免链接错误的DLL.

1. Compile with -static-libstdc++ to avoid wrong DLL being linked.

将libstdc++-6.dll从MinGW\bin复制到与已编译EXE相同的文件夹中.这将导致Windows始终链接正确版本的DLL.

Copy libstdc++-6.dll from MinGW\bin into the same folder as the compiled EXE. This will cause windows to link always the correct version of the DLL.

尽管问题很具体，但我希望它也能对其他人有所帮助. ;)

Although the problem is very specific, I hope that it helps others too. ;)
