Android 开发环境建立-gcc 的问题

安装配置Ubuntu 的Android开发环境现在开始了漫长的编译过程，当然成功不会一蹴而就的，不出所料，错误出现了

ost C: adb <= system/core/adb/fdevent.c

继续求教于，Google和百度吧，原来是gcc版本的问题

$gcc --version

gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1

研究了一下发现问题主要出在Ubuntu10.4预置了gcc的版本是4.4，该版本编译时对语法要求比较高，因此无法编译源代码，解决方法就是将gcc-4.4降级成gcc-4.3

具体操作：sudo apt-get install gcc-4.3（安装gcc-4.3）

sudo apt-get install g++-4.3（安装g++-4.3）

安装完4.3版本后，执行gcc --version后会发现版本仍然是4.4，因为gcc已经和4.4版本进行了链接，因此需要对gcc重新进行链接

具体操作：sudo ln -f /usr/bin/gcc-4.3 gcc

sudo ln -f/usr/bin/g++-4.3 g++

这样就可以用4.3版本的gcc和g++将原来的覆盖掉，重新进入android源码目录执行make就可以正常编译～～
