eclipse配置c开发环境
1 eclipse配置c开发环境
1.1 缘起
公司同事需要开发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。
首先,Windows下用eclipse玩c用到一下三个东西:
- cygwin(Windows平台的unix模拟程序,包含了gcc和g++)
- 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,然后选 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,请务必安装以下程序,务必安装: gcc-core,gcc-g++,make,gdb,binutils;可以参考: http://www.linuxidc.com/Linux/2011-06/37588.htm。
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。
$ 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 目标:x86_64-pc-cygwin 配置为:/cygdrive/i/szsz/tmpp/gcc/gcc-5.4.0-1.x86_64/src/gcc-5.4.0/configure --srcdir=/cygdrive/i/szsz/tmpp/gcc/gcc-5.4.0-1.x86_64/src/gcc-5.4.0 --prefix=/usr --exec-prefix=/usr --localstatedir=/var --sysconfdir=/etc --docdir=/usr/share/doc/gcc --htmldir=/usr/share/doc/gcc/html -C --build=x86_64-pc-cygwin --host=x86_64-pc-cygwin --target=x86_64-pc-cygwin --without-libiconv-prefix --without-libintl-prefix --libexecdir=/usr/lib --enable-shared --enable-shared-libgcc --enable-static --enable-version-specific-runtime-libs --enable-bootstrap --enable-__cxa_atexit --with-dwarf2 --with-tune=generic --enable-languages=ada,c,c++,fortran,lto,objc,obj-c++ --enable-graphite --enable-threads=posix --enable-libatomic --enable-libcilkrts --enable-libgomp --enable-libitm --enable-libquadmath --enable-libquadmath-support --enable-libssp --enable-libada --enable-libgcj-sublibs --disable-java-awt --disable-symvers --with-ecj-jar=/usr/share/java/ecj.jar --with-gnu-ld --with-gnu-as --with-cloog-include=/usr/include/cloog-isl --without-libiconv-prefix --without-libintl-prefix --with-system-zlib --enable-linker-build-id --with-default-libstdcxx-abi=gcc4-compatible 线程模型:posix gcc 版本 5.4.0 (GCC) $ make -v GNU Make 4.2.1 为 x86_64-unknown-cygwin 编译 Copyright (C) 1988-2016 Free Software Foundation, Inc. 许可证:GPLv3+:GNU 通用公共许可证第 3 版或更新版本<http://gnu.org/licenses/gpl.html>。 本软件是自由软件:您可以自由修改和重新发布它。 在法律允许的范围内没有其他保证。 GNU gdb (GDB) (Cygwin 7.10.1-1) 7.10.1 Copyright (C) 2015 Free Software Foundation, Inc.

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,经过查找发现找 不到jdk路径,可能是win10的问题,因此对eclisp根目录下的eclipse.ini进行修改:
-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
-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 -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
1.4 配置
新建一个c项目,选择cygwin gcc,建立c工程,项目右键Properties->C/C++, Build->toolchain 中确定:
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
按理来说这个时候点击运行就可以编译链接程序了,但是出现错误,但这里只会编译链接, 但不会运行,也不会调试程序,我们还得手动做个简单的配置:
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。
