System prerequisites
All system prerequisites must be ready on your system before IBM® Open XL C/C++ for AIX® and its documentation can be successfully installed.
- Supported platform:
- IBM AIX 7.2 TL5 SP3
- IBM AIX 7.3
Notes:- AIX 7.3 is supported starting from IBM Open XL C/C++ for AIX 17.1.0.1.
- The compiler filesets are not OS specific. If IBM Open XL C/C++ for AIX 17.1.0 is installed on AIX 7.2 TL5 SP3, you do not need to migrate the compiler filesets when the operating system is migrated to AIX 7.3. If an OS-specific fileset is required in the future for a higher level of AIX, it will be identified in a Technote tied to the fix pack that adds support for that version of AIX.
- To install the compiler on an operating system that is newly supported in a fix pack, you must first install the full version and then apply the fix pack. Fix packs are available for download at Fix list for Open XL C/C++ for AIX. To find out the supported versions of Open XL or XL compilers on your AIX operating system, see AIX OS levels supported by Open XL and XL Compilers.
- Required hard disk space: 500 MB. You can use the following command to determine the amount of space available in the default installation location (/opt/IBM/openxlC/17.1.0/):
df -m /opt
If you plan to install the compiler to a nondefault location, you can use the following command:
df -m installation_path
In this command, installation_path represents the nondefault location.
- Required filesets: See the Required filesets for installing IBM Open XL C/C++ section for details.
- Required RAM: 2 GB (Recommended RAM: 4 GB or more)
- Required software for documentation:
- HTML browser
- PDF viewer
Required filesets for installing IBM Open XL C/C++
The following filesets must be installed on your system to install IBM Open XL C/C++ for AIX 17.1.0.
Fileset name | Fileset description | Where to get |
---|---|---|
bos.adt.include | Base application development include files | AIX OS installation image or Fileset information for bos:adt:include |
bos.adt.lib | Base application development libraries | AIX OS installation image or Fileset information for bos.adt.lib |
bos.adt.libm | Base application development math libraries | AIX OS installation image or Fileset information for bos.adt.libm |
At least one of the following locale-specific filesets must be installed on your system. You can find the filesets in your AIX OS installation image or IBM support.
Fileset name | Fileset description |
---|---|
bos.loc.LANG | Base locale support |
bos.loc.pc.LANG | Base system locale PC code set |
bos.loc.utf.LANG | Base system locale UTF code set |
bos.loc.iso.LANG | Base system locale ISO code set |
You can view information about the installed filesets by using the
lslpp
command. For example, to determine if the required
filesets have been installed, use the following
command:
lslpp -L bos.adt.include bos.adt.lib bos.adt.libm bos.loc.\*
MISSING REQUISITES: The following filesets are required by one or more of the
selected filesets listed above. They are not currently installed and could not
be found on the installation media.
bos.adt.libm 7.2.5.0 # Base Level Fileset
This message indicates that the bos.adt.libm fileset is required but not installed.
To install a missing fileset, use the following command:
# installp -acXgd installation_path fileset
In this command, installation_path represents the location of the fileset to be installed.
