Setting up MingW and Code::Blocks in Windows 8 64 bit
提问by Rohit Jain
I am trying to setup MingWand Code::Blockson my Windows 8 64 bitlaptop, and I'm facing some problem while building a main.cppfile. These are the versions that I have installed:
我正在尝试在我的Windows 8 64 位笔记本电脑上设置MingW和Code::Blocks，但在构建文件时遇到了一些问题。这些是我安装的版本：main.cpp
- x86_64-w64-mingw32-gcc-4.7.4-release-win64_rubenvb.7zfor MingW(4th one in that list), and
- codeblocks-12.11-setup.exefor Code::Blocks.
- 用于MingW 的x86_64-w64-mingw32-gcc-4.7.4-release- win64_rubenvb.7z（该列表中的第四个），以及
- 用于Code::Blocks 的codeblocks-12.11-setup.exe。
I've set the path to mingw64\binin the environment variable. Also, in the Code::Blocks compiler settings, I have set path for all ToolChain Executables. There are two gccin the MingWbin path. One is - gcc.exeand other is - x86_64-w64-mingw32-gcc.exe. Same for C++ Compiler, Linker for static and dynamic libs. Now when I try to build a simple Hello Worldfile, it shows some errors:
我已经mingw64\bin在环境变量中设置了路径。此外，在 Code::Blocks 编译器设置中，我为所有ToolChain Executables设置了路径。有两个海湾合作委员会在MingW平台bin路径。一个是 -gcc.exe另一个是 - x86_64-w64-mingw32-gcc.exe。C++ Compiler相同，静态库和动态库的 Linker相同。现在，当我尝试构建一个简单的Hello World文件时，它显示了一些错误：
obj\Debug\main.o -- In function swscanf
c:\mingw\mingw64\bin\..\lib\gcc\x86_64-w64-mingw32.7.3\..\..\..\..\x86_64-w64-mingw32\include\wchar.h -- undefined reference to `__gxx_personality_sj0'
obj\Debug\main.o -- In function `wscanf':
c:\mingw\mingw64\bin\..\lib\gcc\x86_64-w64-mingw32.7.3\..\..\..\..\x86_64-w64-mingw32\include\wchar.h -- undefined reference to `__gxx_personality_sj0'
Similarly there are many errors and undefined references for - fwprintf, wprintf, std:cout, etc..
同样存在许多误区和未定义的引用- ，fwprintf，wprintf，std:cout等。
I'm sure there is some configuration problem, but I cannot find out what's the issue. Can any one take a look at the problem.
我确定存在一些配置问题，但我无法找出问题所在。任何人都可以看看这个问题。
Here's the code I'm running:
这是我正在运行的代码：
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}

If you don't require 64 bit support, consider downloading "codeblocks-12.11mingw-setup.exe"
It packs its own 32 bit mingw and has everything preconfigured for you.
Otherwise, if you still need to compile amd64 apps:-
Assuming you extracted to D:\Mingw64, under the "Tool Chain Executables" tab, set the "Compiler's Installation Directory" to "D:\Mingw64\bin", Then click auto-detect to check whether code::blocks likes what it finds.
如果您不需要 64 位支持，请考虑下载“codeblocks-12.11mingw-setup.exe”
它打包了自己的 32 位 mingw 并为您预先配置了所有内容。
否则，如果你仍然需要编译amd64应用程序：-
假设你解压到D:\Mingw64，在“Tool Chain Executables”选项卡下，将“Compiler's Installation Directory”设置为“D:\Mingw64\bin”，然后点击auto -detect 来检查 code::blocks 是否喜欢它找到的东西。
If everythings Ok, make sure the rest of the fields are as follows:-
如果一切正常，请确保其余字段如下：-
C compiler: x86_64-w64-mingw32-gcc.exe
C++ compiler: x86_64-w64-mingw32-g++.exe
Linker for dynamic libs: x86_64-w64-mingw32-g++.exe
Linker for static libs: x86_64-w64-mingw32-ar.exe
Debugger: GDB/CDB Debugger...
Ressource compiler: x86_64-w64-mingw32-windres.exe
Make program: mingw32-make.exe
Click on the "Additional Paths" tab and enter the following line:- (the path is correct for ver 4.7.4,the one you downloaded. It ends with 4.7.3)
单击“其他路径”选项卡并输入以下行：-（路径对于版本 4.7.4 是正确的，即您下载的版本。以 4.7.3 结尾）
D:\Mingw64\libexec\gcc\x86_64-w64-mingw32.7.3\
Click on the "Search directories" tab to the imediate left "Toolchain Executables"
Add the following paths:-
单击左侧“工具链可执行文件”的“搜索目录”选项卡，
添加以下路径：-
D:\Mingw64\include
D:\Mingw64\x86_64-w64-mingw32\include
D:\Mingw64\x86_64-w64-mingw32\include\c++.7.3
D:\Mingw64\x86_64-w64-mingw32\include\c++.7.3\backward
D:\Mingw64\x86_64-w64-mingw32\include\c++.7.3\x86_64-w64-mingw32
D:\Mingw64\lib\gcc\x86_64-w64-mingw32.7.3\include
Click on the "linker" tab and add the following paths:-
单击“链接器”选项卡并添加以下路径：-
D:\Mingw64\Lib
D:\Mingw64\x86_64-w64-mingw32\lib
And finally click on the "Compiler Settings tab", Click on "Other options" and add:-
最后单击“编译器设置选项卡”，单击“其他选项”并添加：-
-m64
One last thing-> remember to save those settings to disk!
If it crashes while you test this new config, you might wish you had!
Do this (I think) either by "File->Save Everything" or restarting code::blocks ...without another instance running.
最后一件事-> 记住将这些设置保存到磁盘！
如果它在您测试这个新配置时崩溃，您可能希望自己有！
执行此操作（我认为）通过“文件->保存所有内容”或重新启动 code::blocks ...而无需另一个实例运行。

Peace! Dear brother, I think you need this:
和平！亲爱的兄弟，我想你需要这个：
(1) std::cout << "Hello world!" << std::endl;
(1) std::cout << "Hello world!" << std::endl;
You need to put "std::function_name" whenever you are using a predefined function from iostream.h, because this is you way access it in GCC, which Code::Blocks uses.
每当您使用 iostream.h 中的预定义函数时，您都需要放置“std::function_name”，因为这是您在 Code::Blocks 使用的 GCC 中访问它的方式。
(2) Try it compiling by omitting "using namespace std;" from your code. Because I've compiled C and C++ code many times in Code::Blocks on 32-bit Windows XP, and it did!
(2) 尝试通过省略“using namespace std;”进行编译 从你的代码。因为我已经在 32 位 Windows XP 上的 Code::Blocks 中多次编译了 C 和 C++ 代码，而且它做到了！
(3) Make sure the path is set to the directory "mingw\bin".
(3) 确保路径设置为目录“mingw\bin”。
(4) Ensure if you have 64-bit MinGW installed and path set to its "bin" directory (if you want to compile for 64-bit). It will compile for 64-bit by default.
(4) 确保您安装了 64 位 MinGW 并将路径设置为其“bin”目录（如果您想编译为 64 位）。默认情况下，它将编译为 64 位。
(5) Try the flags/arguments "-m32" and "-m64" for compiling for 32- and 64-big respectively.
(5) 尝试使用标志/参数“-m32”和“-m64”分别为 32- 和 64-big 编译。
