cmake的安装一路解决问题

前言：

今天开始一个新的项目，从git上面拉取到了项目的代码，这个项目用的是cmake编译的，之前还没有用过cmake，所以应该是要安装一下

1.先用已经存在的脚本试着运行一下

./cmk: line 48: cmake: command not found

提示cmake命令不存在，果然是要安装一下

2.安装cmake

sudo apt install cmake

3.装完之后，再运行一下

cmake: error while loading shared libraries: librtmp.so.0: cannot open shared object file: No such file or directory

提示librtmp.so.0这个库不存在，，查了一下发现我的虚拟机上这个库在/usr/local/lib/目录下面

4.按照网上的方法，把路径写到/etc/ld.so.conf下面

vi /etc/ld.so.confsudo vi /etc/ld.so.conf/sbin/ldconfig -v

结果还是不行

5.经过同事提醒，确认cmake是否安装上了，使用ldd命令查看库的依赖关系（惭愧，ldd命令之前可能见过没用过。。。，）

zqq@zqq-virtual-machine:~$ cd /usr/lib/x86_64-linux-gnu/

存在两个问题

1./usr/bin/cmake: /usr/local/lib/libcurl.so.4: no version information available (required by /usr/bin/cmake)

2.librtmp.so.0 => not found

libcurl.so.4网上查说是冲突了 librtmp.so.0动态库没找到

解决方法：

1. ldconfig -p | grep libcurl.so.4使用这条命令查看libcurl.so.4的路径，

zqq@zqq-virtual-machine:/usr/lib/x86_64-linux-gnu$ ldconfig -p | grep libcurl.so.4libcurl.so.4 (libc6,x86-64) => /usr/local/lib/libcurl.so.4libcurl.so.4 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcurl.so.4

删除掉/usr/local/lib/libcurl.so.4，使用软连接到usr/lib/x86_64-linux-gnu/libcurl.so.4.4.0

zqq@zqq-virtual-machine:/usr/lib/x86_64-linux-gnu$ sudo rm -rf /usr/local/lib/libcurl.so.4
zqq@zqq-virtual-machine:/usr/lib/x86_64-linux-gnu$ sudo ln -s /usr/lib/x86_64-linux-gnu/libcurl.so.4.4.0 /usr/local/lib/libcurl.so.4

2.看到cmake的库依赖基本上都在/usr/lib/x86_64-linux-gnu/这个路径，把librtmp.so.0复制到前面的路径下面

最终：

cmake -version查看信息正常
