Generating a Compression Algorithm RPM Package

This document uses GLZ 1.0.0 as an example. Replace it with the actual GLZ version number.

  1. Install rpmbuild.
    1
2
    		 
    yum install rpmdevtools -y
rpmdev-setuptree

    If you perform the compilation as the root user, an rpmbuild directory is generated in the /root directory. The compilation will occupy 20 GB to 30 GB. If the /root directory has a smaller space, you can change the target directory from rpmbuild to another, for example, /home.

    1. Modify the .rpmmacros file after running the rpmbuild command. 
      1
      		 
      vi /root/.rpmmacros

      Change %_topdir to /home/rpmbuild, as shown in Figure 1.

    2. Run the rpmbuild installation command again.

  2. Copy the algorithm dynamic library.

    Copy the compression algorithm dynamic library to /home/rpmbuild/BUILD/.

    mkdir -p /home/rpmbuild/BUILD/glz-1.0.0
cp /usr/lib64/libglz.so /home/rpmbuild/BUILD/glz-1.0.0/
  3. Edit the glz.spec file.

    vi /home/rpmbuild/SPECS/glz.spec
