无论代码如何，MinGW .exe 都需要一些 gcc dll? [英] MinGW .exe requires a few gcc dll's regardless of the code?
问题描述
使用 MinGW 编译时，我必须在 exe 运行之前从 MinGW bin 目录中复制某些 dll 文件(即使使用-static"和/或-static-libstdc++"也是如此.)我该如何改变?是否有我必须使用的特殊版本的 MinGW?最终，我希望能够只使用目录中的 exe(并且没有设置 Windows 环境变量)来运行程序.这些文件是:
When compiling with MinGW, I have to copy over certain dll files from the MinGW bin directory before the exe will run (Even when using "-static" and/or "-static-libstdc++".) How do I change that? Is there a special build of MinGW that I have to use? Ultimately I want to be able to run the program with nothing but the exe in the directory (and no windows environment variables set.) These File's are:
- libstdc++-6.dll
- libgcc_s_seh-1.dll
- libwinpthread-1.dll
这是我休耕的完整步骤列表:
And here is the complete list of step's I fallow:
- 打开代码::块
- 选择文件->新建->项目->控制台"
- 填写项目Hello World"的项目设置
- 右键单击项目->构建选项...->Hello World(根目标)->其他选项
- 在已设置的-fexceptions"下输入-static"(或-static-libstdc++")
- CTRL-F9 : 构建项目(不执行)
- 在 Windows 资源管理器中导航到并运行构建的Hello World.exe"文件.
- 当弹出消息错误:您的计算机缺少 libstdc++-6.dll"时，单击确定".
- 将libstdc++-6.dll"从/MinGW/bin/目录复制到Hello World.exe"目录中.
- 运行Hello World.exe"
- 对于显示错误:您的计算机中缺少 libgcc_s_seh-1.dll"的消息，单击确定".
- 将libgcc_s_seh-1.dll"复制到Hello World.exe"目录中.
- 重复并最终复制libwinpthread-1.dll".
查看消息
- Open Up Code::Blocks
- Select "File->New->Project->Console"
- Fill out the project settings for project "Hello World"
- Right click Project->Build Options...->Hello World (Root target)->Other Options
- Enter "-static" (or "-static-libstdc++") under the already set "-fexceptions"
- CTRL-F9 : Build Project (Without executing)
- Navigate to, in Windows Explorer, and run the built "Hello World.exe" file.
- Click "OK" when a message pop's up saying "Error: libstdc++-6.dll is missing from your computer."
- Copy "libstdc++-6.dll" from the /MinGW/bin/ directory, into the "Hello World.exe" directory.
- Run "Hello World.exe"
- Click "OK" for the message saying "Error: libgcc_s_seh-1.dll is missing from your computer."
- Copy "libgcc_s_seh-1.dll" into the "Hello World.exe" directory.
- Repeat and end up copying "libwinpthread-1.dll" over aswell.

Hello World!
我的命令行是:
g++.exe -Wall -fexceptions -static -static-libgcc -static-libstdc++ -g -static-libgcc -static-libstdc++ -L. -c "C:Users\______DesktopHello Worldmain.cpp" -o objDebugmain.o
g++.exe -o "binDebugHello World.exe" objDebugmain.o
需要上面提到的所有dll文件.而且，为了安全起见，代码是:
With all the dll files mentioned above required. And, just to be safe, the code is:
// main.cpp
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}
推荐答案
你的命令错了！
转到 main.cpp 文件所在的目录，然后尝试以下操作.
Go to the directory where your main.cpp file is, and try the following.
g++.exe -Wall -c -g main.cpp -o objDebugmain.o
g++.exe -static -static-libgcc -static-libstdc++ -o "binDebugHello World.exe" objDebugmain.o
那么您将不再需要复制 DLL(用于您的 Hello World 程序).
then you'll no longer need to copy the DLLs (for your Hello World program).
其他注意事项:
MinGW安装说明推荐设置
The MinGW installation instructions recommends setting
c:minGW;c:MinGWin;
到 PATH 环境变量.
to the PATH environment variable.
通常是
-static -static-libgcc -static-libstdc++
链接器选项应该可以工作(一次尝试所有 3 个).但不适用于 libwinpthread-1.dll.
linker options should work (try all 3 of them at once). But not for libwinpthread-1.dll.
另外，在重新编译之前尝试clean.
Also, try to clean before recompiling.
没有-static-something"命令.
There's no "-static-something" command.
只有标准库 libgcc 和 libstdc++ 可以设置为静态链接.
Only standard libraries libgcc and libstdc++ can be set to static linking.
对于其他库，您首先使用-static"切换到静态链接，然后列出要包含在单独命令中的库，即-lpthread".
For other libraries, you first switch to static linking with "-static" and then list the libraries to include with separate commands, i.e. "-lpthread".
Cmake 用户应该尝试添加:
set(CMAKE_CXX_STANDARD_LIBRARIES "-static-libgcc -static-libstdc++ -lwsock32 -lws2_32 ${CMAKE_CXX_STANDARD_LIBRARIES}")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,-Bstatic,--whole-archive -lwinpthread -Wl,--no-whole-archive")
