window cygwin c环境搭建

https://cygwin.com/install.html
下载32 或者64位
下载cygwin，在选择从internet下载的时候建议添加镜像站，提高下载速度http://mirrors.163.com/.help/cygwin.html
选择从互联网安装, 在"User URL"处输入以下地址http://mirrors.163.com/cygwin/
在搜索输入框搜索下面的东西然后点击Skip就会变成一个版本号， 而右边有一个bin,出现了一个x,再点击可能会出现版本号变化，甚至 New的字段会出现src源代码也勾选，然后最后又变成了skip,也就是不下载，按照国际惯例教程，都是选择带gun字样的进行安装，
搜索的时候View选择full，

gcc, gcc-core, gcc-g++, gcc-mingw-core, gcc-mingw-g++, make , gdb, binutils
我就下载了gcc-core,gcc-g++, make ,gdb
如果在eclipse跑起来出现了一个问题也就是cygwin提示的问题的话说明没有安装好，我刚开始的时候以为搜索需要按回车键结果直接就下载某些东西了，导致一直报错，后面我把cygwin目录删除了重新装了一遍才好。
然后在eclipse点击锤子就可以进行编译了，然后点击源文件->运行就可以看到控制台输出了.
下一步就会进行下载
最后就完成安装了，
当下次还需要安装的时候可以重新打开安装包，默认将识别上次的配置。
配置环境变量
类似这样的路径
F:\cygwin64\bin;
然后控制台输入

make -version

出现了下面的类似就是代表make成功了 输入

gcc --version

如果能看到版本号也说明gcc也成功下载了

用eclipse开发 c

http://www.eclipse.org/downloads/packages/eclipse-ide-cc-developers/keplersr2
下载和电脑java 32或者64，一定要一样，不然会打开出现找不到jni xx .dll
新建C/C++项目
在Executable选项卡中可以看到右边 分别列出来了识别到的c编译器
Cross GCC Cygwin GCC Microsoft Visual C++
如果没有Cygwin说明环境变量的配置是有问题的.

如果还需要带java的话。。http://www.eclipse.org/downloads/eclipse-packages/
下载java的se,然后再下载cdt插件。http://www.eclipse.org/cdt/http://www.eclipse.org/cdt/downloads.phphttps://jingyan.baidu.com/article/456c463b67b4310a59314468.html
c代码hello world

#include <iostream>
using namespace std;

int main() {
    cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
    return 0;
}

我的做法是新建C++ Project ->Executable -Hello World C++ Project -ToolChains选择Cygwin GCC
点击Next会自动配置Source目录。
不然的话比较乱的，没有source目录的话。
