if compile error,can""t find error.h in some files,use the following command:
sudo ln -sv /usr/src/linux-headers-2.6.38-10/arch/x86/include/asm /usr/include/asm
在/usr/bin目录
cd /usr/bin mv gcc gcc_bk mv g++ g++_bk mv cpp cpp_bk mv c++ c++_bk Use the newest version ln -s /usr/gcc-4.6.1/bin/gcc /usr/bin/gcc ln -s /usr/gcc-4.6.1/bin/g++ /usr/bin/g++ ln -s /usr/gcc-4.6.1/bin/cpp /usr/bin/cpp ln -s /usr/gcc-4.6.1/bin/c++ /usr/bin/c++
Add following into /etc/profile file
