编译cmake首先需要gcc环境，可以执行 gcc --version命令看看。
如果没有，可以使用yum或从cd中进行安装，此处是在虚拟机中从cd中进行安装，将cd链接到虚拟机都会吧，此处略去，，，，，
链接好虚拟机启动后登陆，运行如下命令即可：
cd
mkdir cd-dvd
mount /dev/cdrom cd-dvd
cd cd-dvd/Packages
rpm -ivh kernel-headers-2.6.32-279.el6.x86_64.rpm
rpm -ivh glibc-headers-2.12-1.80.el6.x86_64.rpm --force --nodeps
rpm -ivh glibc-devel-2.12-1.80.el6.x86_64.rpm --force --nodeps
rpm -ivh libgomp-4.4.6-4.el6.x86_64.rpm
rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
rpm -ivh gcc-4.4.6-4.el6.x86_64.rpm
rpm -ivh cpp-4.4.6-4.el6.x86_64.rpm --force --nodeps
rpm -ivh libmpcdec-1.2.6-6.1.el6.x86_64.rpm --force --nodeps
rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm
rpm -ivh libstdc++-devel-4.4.6-4.el6.x86_64.rpm
rpm -ivh gcc-c++-4.4.6-4.el6.x86_64.rpm --force --nodeps
中途遇到的几个问题：
1、/usr/libexec/gcc/x86_64-RedHat-linux/4.4.6/cc1: error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory
最后发现是需要安装mpfr-2.4.1-6.el6.x86_64.rpm
2、---------------------------------------------

Log of errors: /usr/local/cmake-3.0.2/Bootstrap.cmk/cmake_bootstrap.log

最后发现是需要安装gcc-c++环境
rpm -ivh libstdc++-devel-4.4.6-4.el6.x86_64.rpm
rpm -ivh gcc-c++-4.4.6-4.el6.x86_64.rpm --force --nodeps
