Installation Procedure

   

1. Retrieve SACLIB and install it on your machine (see Section 1.1).
2. Retrieve GRÖBNER. The file available in the directory stated in Section 1.1 is a compressed tar-file, GB.tar.Z. (When using ftp, make sure to transfer in binary mode!).
3. Move the file into the directory that should be the parent directory of the ``Gröbner-directory'', see also Section 1.3.
4. Uncompress the file with the command
   unix%
   uncompress GB.tar.Z
5. Extract the directory structure from the tar-file with the command
   unix%
   tar -xvf GB.tar
   A directory called Groebner will be created, which contains the directories described in Section 1.4.
6. Modify the installation script so that it fits to your environment. Use an available text editor (e.g. vi). (See the description of install_groebner in Section 1.4 and the comments in the script).
   unix%
   cd Groebner/bin
   unix%
   vi install_groebner
    
7. Run the installation script.
   unix%
   install_groebner
8. • Make sure that the directory, which contains the scripts groebner and xgroebner, is contained in your search path or
   • Move/Copy those scripts into any of the directories contained in the search path or
   • Provide symbolic links from a directory in the search path to those scripts.
9. GRÖBNER is now installed. In order to change e.g. the coefficient domain of polynomials or the ordering of monomials you have to
   • Edit the respective setup file (see page ) in the directory GROEBNER/include.
   • Recompile GRÖBNER, i.e. issue the command make in the directory GROEBNER/src,
   • Eventually recompile the I/O library, i.e. issue the command make in the directory GROEBNER-IO/src. This step is of course only necessary when the changes have an impact on in- or output. For instance, changing the coefficient domain influences the IO-library, whereas changing the ordering of monomials does not.
   • Recompile the application program, i.e. issue the command make in the directory APP.
   You do not have to reinstall the library!
