新装的mingw   的include目录下没有C++
如没有类似的    C:\MinGW\include\c++\3.4.5



网上mingw环境配置怎么怎样多样
 
求高手解释一下 不同版本对应如何配置mingw

重新下载一个装下呗

下载之后应该有个 mingw-get-inst.exe 运行这个安装。
升级的话用 mingw-get upgrade / update

直接运行gcc看环境对不对

我只注册了path lib include  但include中没有写上C++的

好像一切正常，codeblocks也找得到，

就是想问  面对网上众多mingw环境配置方法 ， 哪一种才最好

去官网找官方的配置方法 理论上说最好的

好吧，去官网
官网写着

Right-click on your "My Computer" icon and select "Properties".
Click on the "Advanced" tab, then on the "Environment Variables" button.
You should be presented with a dialog box with two text boxes. The top box shows your user settings. The PATH entry in this box is the one you want to modify. Note that the bottom text box allows you to change the system PATH variable. You should not alter the system path variable in any manner, or you will cause all sorts of problems for you and your computer!
Click on the PATH entry in the TOP box, then click on the "Edit" button
Scroll to the end of the string and at the end add
;<installation-directory>\bin
press OK -> OK -> OK and you are done.
NOTE: Substitute <installation-directory> with the FULL absolute path name of the installation target directory you chose (ie C:\MinGW);

只需要配置path

老版本的装上配置个环境变量就好了
