If the XL C/C++ compiler
has been installed to a non-default directory, you must use vacppndi to install
PTFs.
About this task
Note: The vacppndi tool
enforces that you install the PTF vacpp.ndi fileset
before using the tool to install the PTF to a non-default location.
To
update a non-default installation, do the following:
- Begin by installing the vacpp.ndi fileset
included in the PTF. This fileset must be installed first, so that
the vacppndi script
inside it can be used to correctly install the remaining filesets.
To determine the version number of the vacpp.ndi fileset
currently installed on your system, run the command:
lslpp -l vacpp.ndi
To
install a new version of the vacpp.ndi fileset,
run the command:
installp -aYgd ptf_images_location -e logfile vacpp.ndi
- Create a text file listing the PTF filesets you want to
install. This text file must contain the name of a single PTF file
on each line. You can use the ls command to do
this: ls source_path > ptf_names_file.
For example:
ls /compiler/update/ > /home/user/update.list
update.list contains all the
updated fileset names, one for each line. For example: vac.C.11.01.0000.0001.bff
- Use the perl command to run the vacppndi script:

>>-perl--/usr/vacpp/bin/vacppndi-- -d--source_path-- -u--ptf_names_file-->
>--+--------------+--+-----------------+--+-------+------------->
'- -e--logfile-' '- -b--target_dir-' '- -rte-'
>--+-----------+-----------------------------------------------><
'- -version-'
perl /usr/vacpp/bin/vacppndi -d source_path -u ptf_names_file [-e logfile]
-b [target_dir]
where: - -d source_path
- Specifies the directory where the filesets are located. This path
might also be a mounted CD-ROM drive.
- -u ptf_names_file
- Specifies the text file containing the names of PTF filesets you
want to install.
- -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.
- -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, an error
message is produced and the installation stops.
- -rte
- Specifies that only the runtime component is installed.
- -version
- Displays the version of the non-default installation tool.
Note: The installation script creates a compressed TAR backup
of the compiler files that exist before the PTF update. If a problem
is encountered with the installation of the PTF update or with the
PTF update itself, you can restore from this backup file target_dir.tar.Z to
uninstall the PTF update.
The following example uses the vacppndi Perl script
to install all available PTF filesets in the /compiler/update/ 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 /compiler/update/ -u /compiler/update/ptflist
-b /compiler/xlcpp/ -e /tmp/xlcpp.ndi.inst.log
