从源码安装cmake

##安装环境:ubuntu16.04

## 安装cmake之前需要确认已经安装make、gcc、g++，用make -v | gcc -v | g++ -v可查看是否已经安装，如果没有安装用apt-get安装一下(也可从源码安装)：

sudo apt-get install gcc

sudo apt-get install g++

sudo apt-get install make

## cmake下载：https://cmake.org/download/

wget https://github.com/Kitware/CMake/releases/download/v3.14.3/cmake-3.14.3.tar.gz #该方法下载较慢，建议从浏览器直接下载

注：

源码安装cmake-3.14-3的时候碰到了一些无法解决的错误，贴到了随笔最后，有解决的伙伴可以给个方法(已解决，原因是压缩包下载错误)

##cmake解压: tar -zxvf cmake-3.13.4.tar.gz / tar -zxvf cmake-3.14.3.tar.gz

##cmake安装

step1：./bootstrap

step2:make

step3：make install

step4：cmake --version

如下安装成功：

3.13.4安装成功

 

3.14.3安装成功

 

 step5<可选>: make uninstall #卸载(我将3.13.4版本的卸载了，保留了3.14.3的)

 

##问题记录（该问题后来定位是zip的压缩包是用于windows版本的，还是要注意看清楚每一行英文，我晕，下载tar.gz版本即可，如下错误不关注，留下给自己提个醒）

 

 

1 cmake-3.14.3.zip解压完成后，cd cmake-3.14.3; chmod 775 ./configure; ./configure报错如下：

./configure: 3: exec: /home/guang/3rdTools/cmake-3.14.3/bootstrap: Permission denied

解决：需要首先执行bootstrap(没有进一步研究为什么，网络上给的答案)

chmod 775 bootstrap

./bootstrap

执行./bootstrap报错，还未找到答案
