Non-default installation procedure

To install XL C/C++ to a non-default location, first use installp to install the vacpp.ndi fileset, then use the vacppndi Perl script included in that fileset to install the compiler.

About this task

Follow these steps to install XL C/C++ to an alternate location:

  1. First use the installp command to install the vacpp.ndi fileset. Run the command:
    installp -aYgd install_images_location -e logfile vacpp.ndi vacpp.licAgreement

    >>- ---installp-- -aYg--+-----+--+-----+--+------------------------------+--+--------------+--vacpp.ndi--vacpp.licAgreement-><
                            '- -p-'  '- -X-'  '- -d--install_images_location '  '- -e--logfile-'                                  
    
    
    -aYg
    Specifies that all the latest installable filesets available in the install_images_location directory are applied and that the required software license agreement is accepted.
    -d install_images_location
    Specifies the directory where the filesets are located. This path might also be a mounted CD-ROM drive.
    -e logfile
    Specifies the name and location of the installation log file. By default, the installation log file vacppndi.log will be stored in your working directory.
    -p
    Performs a preview of the installation process by running the preinstallation checks. See Previewing the installation and license agreements.
    -X
    Attempts to expand the file system at the default location if there is insufficient space to complete the install.

    Example:

    installp -aYgd /cdrom/usr/sys/inst.images -e /tmp/install.log vacpp.ndi \
        vacpp.licAgreement
    Note: This command automatically installs and accepts the license agreement fileset, vacpp.licAgreement, required to install vacpp.ndi.
  2. Install any available updates to the vacpp.ndi fileset. You can download the latest compiler updates from the support Web site: http://www.ibm.com/software/awdtools/xlcpp/aix/support/

    To check the version number of the vacpp.ndi fileset currently installed on your system, use the following command:

    lslpp -l vacpp.ndi

    To install a new version of the vacpp.ndi fileset, use the following command:

    installp -aYgd ptf_images_location -e logfile vacpp.ndi
  3. Install XL C/C++ by entering the following command:

    >>-perl--/usr/vacpp/bin/vacppndi-- -d--source_path-------------->
    
    >--+--------------+--+-----------------+--+-------+------------->
       '- -e--logfile-'  '- -b--target_dir-'  '- -rte-'   
    
    >--+--------+--+-----------+-----------------------------------><
       '- -eval-'  '- -version-'   
    
    
    perl /usr/vacpp/bin/vacppndi -d source_path [-e logfile] [-b target_dir] [-rte]
    [-eval] [-version]
    where:
    -d source_path
    Specifies the directory where the filesets are located. This path may also be a mounted CD-ROM drive.
    -e logfile
    Specifies the name and location of the installation log file. By default, the installation log file vacppndi.log is stored in your working directory.
    -b target_dir
    Specifies the location where the filesets should be copied and expanded. By default, the files are copied to the vacppndi directory in your working directory. If the directory exists already, you will receive an error message and the installation will stop.
    -rte
    Specifies that only the runtime component is installed.
    -eval
    Specifies that the installation is for the evaluation version of XL C/C++.
    -version
    Displays the version of the non-default installation tool.

    The following example uses the vacppndi Perl script to install all available compiler filesets in the /cdrom/usr/sys/inst.images source directory to the non-default location, /compiler/xlcpp/ and writes the installation log file to /tmp/xlcpp.ndi.inst.log.

    Example:

    perl /usr/vacpp/bin/vacppndi -d /cdrom/usr/sys/inst.images -b /compiler/xlcpp/
    -e /tmp/xlcpp.ndi.inst.log 
Results
IBM XL C/C++ for AIX is installed into the chosen location.
