Method of packages_cpm.txt file construction

This document describes the method of constructing packages_cpm.txt file with a concrete example.

The steps of constructing packages_cpm.txt file

  1. Set architecture like ARCHITECTURE, amd64;.
  2. Set build environment like BUILD_ENV, CPM_ENV;, BUILD_ENV, SYSTEM_ENV; or BUILD_ENV, DOCKER_ENV, ./cpm/build_env/docker/ubuntu18.04_for_build_gcc;.
  3. Set installation mode like INSTALL_MODE, source;, INSTALL_MODE, archive; or INSTALL_MODE, auto;
  4. Set installing packages that you want.

Ex. 1) Build and archive the gcc compiler (build all libraries)

When building the libraries from source file, set INSTALL_MODE, source;.

  • sample/packages_cpm_00.txt 
    ARCHITECTURE, amd64;
BUILD_ENV, DOCKER_ENV, ./cpm/build_env/docker/ubuntu18.04_for_build_gcc;

INSTALL_MODE, source;
m4, ==1.4.15;
gmp, ==6.1.0;
mpfr, ==3.1.4;
mpc, ==1.0.3;
isl, ==0.18;
gcc, ==12.1.0;
  • run sample/packages_cpm_00.txt 
    cpm/exe -p sample/packages_cpm_00.txt

Ex. 2) Build and archive the gcc compiler (build only gcc)

To change the installation mode within the same packages_cpm.txt, set INSTALL_MODE once more. (About the scopy of INSTALL_MODE, see INSTALL_MODE)

  • sample/packages_cpm_02.txt 
    ARCHITECTURE, amd64;
BUILD_ENV, DOCKER_ENV, ./cpm/build_env/docker/ubuntu18.04_for_build_gcc;

INSTALL_MODE, archive;
m4, ==1.4.15;
gmp, ==6.1.0;
mpfr, ==3.1.4;
mpc, ==1.0.3;
isl, ==0.18;

INSTALL_MODE, source;
gcc, ==12.1.0;
  • run sample/packages_cpm_02.txt 
    cpm/exe -p sample/packages_cpm_02.txt

Ex. 3) Use gcc compiler as a base environment and install user requiring libraries

When building a gcc-based environment, first set the gcc archive, then set the required libraries.

Case A: Specifying the version

  • sample/packages_cpm_03a.txt 
    ARCHITECTURE, amd64;
BUILD_ENV, CPM_ENV;
INSTALL_MODE, auto;

/*
 * set gcc as a base environmet
 */
gcc, ==12.1.0;

/*
 * install what you want
 */
cmake, ==3.*.*;
googletest, ==1.*.*;
  • run sample/packages_cpm_03a.txt 
    cpm/exe -p sample/packages_cpm_03a.txt

Case B: Not specifying the version

In this case, the latest versions of cmake and googletest among the matching versions of each library will be installed.

  • sample/packages_cpm_03b.txt 
    ARCHITECTURE, amd64;
BUILD_ENV, CPM_ENV;
INSTALL_MODE, auto;

/*
 * set gcc as a base environmet
 */
gcc, ==12.1.0;

/*
 * install what you want
 */
cmake;
googletest;
  • run sample/packages_cpm_03b.txt 
    cpm/exe -p sample/packages_cpm_03b.txt
