CenOS7 源代码安装CMAKE3.12.0

本文是关于cmake 3.12.0 在CenOS7下的安装。

1、安装cmake必要的程序Package：

yum install -y gcc gcc-c++ make automake 

2、wget的安装(为了下载cmake源代码):

yum install -y wget

3、使用wget下载CMake源代码:

wget https://cmake.org/files/v3.12/cmake-3.12.0-rc1.tar.gz

4、解压:

tar -zxvf cmake-3.12.0-rc1.tar.gz

5、进入解压之后的CMake源码目录:

cd cmake-3.12.0-rc1

6、执行configue文件:

./configure

如果上面的语句没有出现问题，请直接执行第7步骤，如果出现以下的错误（.so链接错误），请参照以下解决:

可能出现的错误1:

敲重点的时候：如果这一步你没有执行成功，而是出现了类似以下的Error的话，重点看这里:

-- Found ZLIB: /home/machao/anaconda3/lib/libz.so (found version "1.2.8") 
-- Found OpenEXR: /usr/lib/x86_64-linux-gnu/libIlmImf.so
CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfig.cmake:27 (message):
  The imported target "Qt5::Gui" references the file

     "/usr/lib/x86_64-linux-gnu/libEGL.so"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake"

  but not all the files it references.

Call Stack (most recent call first):
  /usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake:50 (_qt5_Gui_check_file_exists)
  /usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake:72 (_qt5gui_find_extra_libs)
  /usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfig.cmake:158 (include)
  cmake/OpenCVFindLibsGUI.cmake:19 (find_package)
  CMakeLists.txt:535 (include)

解决方法(删除原有的so链接，重新建立链接关系):

删除原有的so链接

sudo rm /usr/lib/x86_64-linux-gnu/libEGL.so

重新建立链接关系:

sudo ln /usr/lib/x86_64-linux-gnu/libEGL.so.1 /usr/lib/x86_64-linux-gnu/libEGL.so

可能出现的Error2:

本人当时安装的时候提示的是类似以下的error:

CMake Error at /usr/home/anaconda3/cmake/Qt5Gui/Qt5GuiConfig.cmake:27 (message):
  The imported target "Qt5::Gui" references the file

     "/usr/lib64/libEGL.so"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/usr/home/anaconda3/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake"

这种解决方法类似上面:

删除原有的so链接:

sudo rm /usr/lib64/libEGL.so;

重新建立链接关系:

sudo ln /usr/lib64/libEGL.so.1 /usr/lib64/libEGL.so

7、编译工程:

gmake

8、安装编译之后的cmake工程

gmake install

9、测试是否安装成功:

cmake --version

如果出现cmake版本信息，则正确安装了。
