Installing CMake

CMake 3.12 or later is required for Hadoop compilation. This document uses CMake 3.12.4 as an example.

• The CMake version provided by CentOS is earlier than 3.12. You need to manually install CMake 3.12.4. The procedure is as follows:
  1. Download the CMake installation archive.

     1	wget https://cmake.org/files/v3.12/cmake-3.12.4.tar.gz

  2. Extract the CMake installation archive.

     1	tar -zxf cmake-3.12.4.tar.gz

  3. Navigate to the directory created by extracting the archive and compile and install CMake.

     1 2 3 4

     cd cmake-3.12.4 ./bootstrap make -j8 make install

  4. Check the CMake version to verify the CMake installation.

     1	cmake --version

     If the version number 3.12.4 is displayed, the installation is successful.

• On the openEuler OS, you can use the Yum repository to install CMake.

  1	yum install cmake
