This guide applies to Version 7.3 of HP C for OpenVMS I64 Systems and all subsequent maintenance releases up to the next release of the product that includes an updated installation guide.
The OpenVMS Software Product Library CD-ROM (media CD-ROM) set provides the following files:
To determine whether the appropriate media CD-ROM is already mounted on your system, contact the appropriate system manager.
HP C provides release notes and a cover letter called Read Before Installing or Using HP C Version 7.n for OpenVMS Industry Standard 64 Systems.
You can extract the HP C release notes to a file and type or print them before starting HP C installation. The HP C release notes are also installed on your system after installation.
You can read the online cover letter provided on the media CD-ROM set or read the printed hardcopy cover letter.
For information about using the CDMENU utility and locating the appropriate media CD-ROM and directory that contains the HP C cover letter, see the first few steps in Section 2.2.
Once the appropriate media CD-ROM has been mounted and the appropriate HP C documentation directory located, do one of the following:
For information about reading the online release notes before installation, use the PRODUCT EXTRACT RELEASE_NOTES command described in Section 2.2 (step 6).
HP strongly recommends that you read the release notes and the cover letter before installing HP C. They contain information about changes to the installation and use of HP C, such as the minimum version of the OpenVMS I64 operating system required for this release of HP C.
After installation, the release notes are installed as text and PostScript form in:
SYS$HELP:CC.RELEASE_NOTES SYS$HELP:CC_RELEASE_NOTES.PS |
You can install HP C on any Itanium processor capable of running OpenVMS I64 Version 8.2-1 or higher. See the OpenVMS Operating System's Software Product Description (SPD 25.01.nn) for details.
HP C 7.3 requires the OpenVMS I64 operating system Version 8.2-1 or higher.
Future HP C releases may require higher versions of the OpenVMS operating system, as described in the release notes or the cover letter.
The OpenVMS I64 operating system comes with a variety of support options (or components). Components include such features as networking and RMS journaling. To use HP C, your system should be running a version of the OpenVMS I64 operating system that includes the base component and the following other components:
For a complete list of the required components, see the HP C Software Product Description (SPD) on the media CD-ROM.
You can use the following optional OpenVMS software with HP C:
Before you install and run HP C 7.3 on a newly-licensed node or cluster, you must first register a License Product Authorization Key (License PAK), using the License Management Facility (LMF).
The specific LMF product name used by HP C is:
The HP C compiler accepts a C-USER PAK. The License PAK may be shipped along with the kit if you ordered the license and media together; otherwise, it is shipped separately to a location based on your license order. If you are installing HP C as an update on a node or cluster already licensed for this software, you have already completed the License PAK registration requirements.
If you are installing prerequisite or optional software along with HP C, review the PAK status and install the PAKs for any prerequisite or optional software before you install HP C.
You must register and load your license for HP C before you start the installation in order to run the Installation Verification Procedure (IVP) and use the software.
To register a license under OpenVMS, log in to a privileged account, such as the system manager's account, SYSTEM. You have a choice of two ways to register a license:
If you plan to use HP C on more than one node in a cluster, you will need to perform a license load on the other nodes after you complete this installation. See Section 3.3.
For complete information on using LMF, see the VMS License Management Utility Manual or the online HELP LICENSE utility.
After you have registered and loaded the license PAK and read the appropriate parts of this installation guide, the installation takes approximately 5 to 15 minutes, depending on your type of media, your system configuration, and the kit components chosen.
To install HP C, you must be logged in to an account that has the SETPRV privilege or at least the following privileges enabled:
Table 1-1 lists the HP C requirements for free disk storage space to install the compiler and the documentation (in .ps, .txt, and .html formats).
| Blocks During Installation | Blocks After Installation |
|---|---|
| 150,000 | 75,000 |
These counts refer to the disk space required on the system disk. The sizes are approximate; actual sizes may vary depending on the user's system environment, configuration, and software options.
To determine the number of free disk blocks on the current system disk, enter the following DCL command:
$ SHOW DEVICE SYS$SYSDEVICE |
Installing HP C requires certain system parameter settings.
The minimum number of free global pagelets (512-byte subpage unit) and global sections needed for the installation depends on whether SYS$SYSTEM:DECC$COMPILER.EXE was previously installed as a shared known image:
These values represent the number of free global pagelets and global sections required for the installation, not the total number you need to run your system and other software.
If you do not ensure that your system has the necessary global pagelets and global section SYSGEN parameters for the installation, the DCL tables can become corrupted in some situations. |
To install and run HP C, you must have sufficient free global pagelets and global sections.
Enter the following DCL command to determine the number of global pagelets required by SYS$LIBRARY:DCLTABLES.EXE:
$ DIR/SIZE SYS$LIBRARY:DCLTABLES.EXE |
This command returns the size (in blocks) of SYS$LIBRARY:DCLTABLES.EXE. As an approximation, use this figure as the number of global pagelets for the file.
You can use the WRITE command with the F$GETSYI lexical function to find the number of free contiguous global pagelets and free global sections. The following example shows how to get this information at your terminal (the default for SYS$OUTPUT):
$ WRITE SYS$OUTPUT F$GETSYI("CONTIG_GBLPAGES")
15848
$ WRITE SYS$OUTPUT F$GETSYI("FREE_GBLSECTS")
24

If the value of free global pagelets or global sections is less than the required value (see Section 1.7.2), you must increase the system parameter setting.
Section 1.7.2.2 describes the procedures for increasing these values using AUTOGEN.
If you do not have enough free global pages or free global sections to install HP C, you can do either of the following:
AUTOGEN automatically adjusts values for parameters that are associated with the values you reset manually. To change system parameters with AUTOGEN, edit the following file:
SYS$SYSTEM:MODPARAMS.DAT |
Use an editor to access the file.
To change a parameter value listed in this file, delete the current value associated with that parameter and enter the new value.
To add a new parameter, add a line to the file that specifies the name of the parameter and its value. For example:
WSMAX = 8096 |
To modify incremental parameters such as GBLPAGES and GBLSECTIONS, use the ADD_ prefix. The following example increases the global page setting by 2000:
ADD_GBLPAGES = 2000 |
After you make all your changes, exit from the editor, then execute the AUTOGEN procedure to recalculate your system parameters and reboot the system:
$ @SYS$UPDATE:AUTOGEN GETDATA REBOOT |
When you specify REBOOT, AUTOGEN does an automatic system shutdown and then reboots the system. Any users logged on to the system are immediately disconnected during the shutdown. The automatic reboot puts the new parameter values into effect.
The AUTOGEN Utility automatically adjusts some of the SYSGEN parameters based on the consumption of resources since the last reboot. If you do not want to take advantage of this automatic adjustment, include the NOFEEDBACK qualifier on the AUTOGEN command line.
For information about using AUTOGEN and its command-line parameters, see the OpenVMS System Manager's Manual: Tuning, Monitoring, and Complex Systems.
HP recommends that you do a system disk backup before installing any software. Use the backup procedures that are established at your site. For details on performing a system disk backup, see the Using VMS BACKUP manual.
