eclipse配置c开发环境

1 eclipse配置c开发环境

 

1.1 缘起

公司同事须要开发c语言,想要配置一个开发环境,考虑使用eclipse+cygwin gcc开发,因 此帮着配置了开发环境。机器配置:win10,4G。html

首先,Windows下用eclipse玩c用到一下三个东西:java

  1. cygwin(Windows平台的unix模拟程序,包含了gcc和g++)
  2. eclipse

1.2 cygwin

cygwin搜索官方网站下载安装程序,选择64位的,打开安装程序setup-x86_64.exe,而后选 install from internet,接着选择存放位置,打开翻_墙(不翻_墙下载会很慢),进入下载列 表,这个列表就是要求你下载什么程序的列表,请务必安装如下程序,务必安装: gcc-core,gcc-g++,make,gdb,binutils;能够参考: http://www.linuxidc.com/Linux/2011-06/37588.htmlinux

将cygwin安装目录\bin加入到环境变量PATH中。好了,开个cmd命令行窗口,分别试一下gcc -v, make -v,gdb -v命令。c++

$ gcc -v
使用内建 specs。
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-pc-cygwin/5.4.0/lto-wrapper.exe

1.3 eclipse

先安装jdk1.8,在eclipse官网下载c++开发ide,eclipse-cpp-neon-1-win32-x8664,打开 eclipse,win10下报错:could not create the Java Virtual Machine,通过查找发现找 不到jdk路径,多是win10的问题,所以对eclisp根目录下的eclipse.ini进行修改:redis

-startup
plugins/org.eclipse.equinox.launcher_1.3.200.v20160318-1642.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.400.v20160518-1444
-product
org.eclipse.epp.package.cpp.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.8
-XX:+UseG1GC
-XX:+UseStringDeduplication
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m

在最前面加上路径sql

-vm
c:\Programs\jdk1.8\bin
-startup
plugins/org.eclipse.equinox.launcher_1.3.200.v20160318-1642.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.400.v20160518-1444

-XX:+UseG1GC

-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m

1.4 配置

新建一个c项目,选择cygwin gcc,创建c工程,项目右键Properties->C/C++, Build->toolchain 中肯定:bootstrap

o_eclipse-c01.png

Current toolchain = Cygwin Gcc
Current builder = Gnu Make Builder

Used tools 有:
GCC Assembler,
GCC Archiver,
Cywgin C++ Compiler,
Cywgin C Compiler,
Cywgin C Linker,
Cywgin C++ Linker。

最后将Display compatible toolchains only选中

按理来讲这个时候点击运行就能够编译连接程序了,可是出现错误,但这里只会编译连接, 但不会运行,也不会调试程序,咱们还得手动作个简单的配置:bash

进入debug configuration对话框,选择C/C++application->test debug,点击Browse…按 钮,选择选择刚才编译出来的exe文件,debug/test.exe,在点击run或debug按钮,ok了。app
