Your distribution kit includes a letter titled Compaq C++ for Compaq Tru64 UNIX. This letter discusses important information that might not be included in this guide. You should read this letter now.

1.1 Reading the Online Release Notes

Compaq C++ provides both online and hardcopy release notes. Compaq strongly recommends that you read the release notes before using the product. The release notes may contain information about changes to the application.

The release notes for Compaq C++ are in subset CXXBASEnnn, where nnn is a number representing the latest release of Compaq C++. For the number of latest subsets, see the Read Before Installing letter. This letter and the release notes are both included on the Media CD-ROM in the following directory:

/cxxnnn/documentation

Installing subset CXXBASEnnn moves the release notes to the following directory location:

/usr/lib/cmplrs/cxx/DECCXXnnn.release-notes

HTML files are also provided for the release notes and some of the product manuals for use with a web browser. See Section 1.5.

1.2 Registering Your Software License

Compaq C++ includes support for the License Management Facility (LMF). You must register your License Product Authorization Key (License PAK) in the License Database (LDB) to use Compaq C++ on a newly licensed node. 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 Compaq C++ as an update on a node already licensed for this software, you have already completed the License PAK registration requirements.

If you are installing prerequisite or optional software along with Compaq C++, review the PAK status and install the PAKs for any prerequisite or optional software before you install Compaq C++.

To register a license under the Compaq Tru64 UNIX operating system, first log in as superuser.

At the superuser prompt, edit an empty PAK template with the lmf register command as follows, and include all the information on your License PAK:

# lmf register

After you register your license, use the following lmf reset command to copy the license details from the LDB to the kernel cache:

# lmf reset

For complete information on using the LMF, see the Guide to Software License Management and the lmf(8) reference page.

1.3 Checking the Software Distribution Kit

Use the Bill of Materials (BOM) to check the contents of your Compaq C++ software distribution kit.

In addition to this guide, the software distribution kit includes the following:

• A CD-ROM optical disk for systems with optical disk drives
• A CD-ROM booklet and CD-ROM read first letter

If your software distribution kit is damaged or incomplete, contact your Compaq representative.

1.4 Checking Installation Procedure Requirements

This section discusses various requirements for installing Compaq C++.

Installing Compaq C++, including running the Installation Verification Procedure (IVP), takes approximately 5 to 10 minutes, depending on your type of media and system configuration.

1.4.1 Checking Login Privileges

You must have superuser privileges to install the Compaq C++ software and to register the license PAK.

1.4.2 Checking Hardware Requirements

To install Compaq C++, you need the following hardware:

• Software distribution device (if installing from media)
  Locate the CD-ROM drive for the CD-ROM software distribution media. The CD-ROM booklet or the documentation for the CD-ROM drive you are using explains how to load the CD-ROM media.
• Terminal
  You can use either a hardcopy or video terminal to communicate with the operating system and respond to prompts from the installation procedure.

For additional hardware requirements, see the Compaq C++ Software Product Description (SPD) contained on the Media CD-ROM.

1.4.3 Checking Software Requirements

Compaq C++ Version 6.2 requires the Compaq Tru64 UNIX operating system Version 4.0 or higher. Future Compaq C++ releases may require higher versions. See the Read Before Installing letter (included on the CD-ROM or the online release notes for information about the required minimum version of the operating system.

Compaq C++ requires that the following software subsets be loaded on the system where you install Compaq C++ (nnn is the number representing the latest release).

• OSFBASEnnn---the "Base System" subset
• OSFPGMRnnn---the "Standard Programmer Commands" subset
• OSFCMPLRSnnn---the "Compiler Back End" subset
• OSFINCLUDEnnn---the "Standard Header Files" subset
• CXLLIBAnnn---the archived class library subset

To install the Compaq C++ reference pages (manual pages), the following software subset must be installed on the system where you install Compaq C++:

• OSFDCMTnnn---the "Documentation for Reference Pages" subset

To install X Motif header files for Compaq Tru64 UNIX software, the following software subset must be installed on the system where you install Compaq C++:

• OSFXDEVnnn---the "X Window and X/Motif Software Development" subset

To check whether these subsets are loaded:

1. Log in to the system where you will install Compaq C++.
2. Enter the following command:

   # setld -i | grep -E 'OSFBASE|OSFPGMR|OSFCMPLRS|OSFINCLUDE|CXLLIBA|OSFDCMT|OSFXDEV'

If you do not log in as superuser (login name root), you must enter the full path of the command.

Check the displayed rows for the name of the relevant subset and any related patches. The word "installed" appears in a row after the subset identifier when a subset is loaded. If the word "installed" does not appear (the second column in a row is blank), the subset or patch is not loaded. In this case, you must load the missing Compaq Tru64 UNIX software before installing Compaq C++. (For information on how to load the operating system software, see the Guide to Installing Compaq Tru64 UNIX .)

1.5 Determining Which Documentation Subsets to Load

To view this documentation after installation, point your web browser to /usr/share/doclib/cplusplus /index.htm.

1.6 Installing from Media or Using the Remote Installation Service

Someone from your site must perform at least one Compaq C++ installation from the distribution medium. Your site system manager can then decide whether or not to make a Compaq C++ distribution kit available on line so that subsequent installations of Compaq C++ can use the Remote Installation Service (RIS). For information on extracting Compaq C++ subsets to a RIS distribution area, see the Guide to Sharing Software on a Local Area Network.

If you expect to use Compaq C++ subsets from the RIS area of a remote system for installation on your local system, first check with your site system manager to ensure that:

• A Compaq C++ network kit is available for use.
• Your system is registered as a RIS client.

If Compaq C++ subsets are available to you on a RIS server system, you must know the name of that system.

For more information on installing Compaq C++ from a RIS distribution area, see Section 3.2.

1.7 Backing Up Your System Disk

Compaq recommends that you back up your system disk before installing any software. For information about backing up your system disk, see the Compaq Tru64 UNIX system documentation.

1.8 Stopping the Installation

To stop the installation procedure at any time, press Ctrl/C. You must then delete files created up to this point interactively. To get a list of the directories and files created during the Compaq C++ installation, use the following command:

# /usr/sbin/setld -i subsetname

In this command, subsetname is the name of the Compaq C++ subset that you have chosen to install.

1.9 Checking Current Disk Space

To check the current amount of free space for a directory path, log in to the system where you will install Compaq C++. You can check which directories are mounted and where they are by viewing the /etc/fstab file. For example:

# more /etc/fstab /dev/rd0a:/:rw:1:1:ufs:: /dev/rd0g:/usr:rw:1:2:ufs:: /usr/staff/r1/leslie@bigsys:/usr/staff/r1/leslie:rw:0:0:nfs:bg: /usr/man@bigsys:/usr/man:ro:0:0:nfs:bg:

The display indicates that /usr (mounted to /dev/rd0g) is the only mount point that affects where Compaq C++ files will reside; the system has only one local disk drive, and the /usr/lib and file system reside in the g partition of the disk on that drive.

To check the total space and the free space for the directories where Compaq C++ will reside, enter the df command. Given the previous display of the /etc/fstab file, which shows that only /usr is a mount point, you need to check free space only in the /usr file system. For example:

# df /usr Filesystem Total kbytes kbytes % node kbytes used free used Mounted on /dev/rd0g 122598 54447 55892 49% /usr

This display shows that there are 55,892 Kbytes free. For space requirements to install this product, see the Software Product Description for Compaq C++ for Compaq Tru64 UNIX.

On systems where /usr/lib and /usr/man are mounted to different devices from /usr, enter the following command:

# df /usr/lib /usr/man

In this case, you compare space required for Compaq C++ files in /usr/lib to the free space displayed in the first line of the df output list, and compare the space required for Compaq C++ files in /usr/man to the free space displayed in the second line of that list.

1.10 Increasing Disk Space by Using Alternative Disks

The Compaq C++ installation procedure creates the following directories and loads files into subordinate directories:

/usr/include/cxx /usr/lib/cmplrs/cxx

If the /usr/lib/cmplrs and /usr/include directory nodes in the previous paths do not exist, the installation procedure creates and uses them.

If you find that there is insufficient disk space for the Compaq C++ subsets and you know that you have additional space on alternative disks or disk partitions for your system, perform the following steps before installing Compaq C++:

1. Log in as superuser.
2. Create the directory /usr/lib/cmplrs.
3. Specify in the /etc/fstab file that one or more of the newly created directories are mount points to new disk partitions where there is additional space.
4. Enter the mount -a command so that the new mount points take effect.

This chapter describes the special requirements necessary to install Compaq C++ on Version 4.0 and higher systems.

2.1 Deleting Old Subsets

If you deleted any of these subsets (because they were old---see Section 2.1), you should install the latest versions from the current kit.

The following online documentation subset is optional:

CXXHTML nnn

Compaq C++ HTML documentation

This chapter describes how to install Compaq C++. Before you start the installation, read Chapter 1. You can install Compaq C++ locally (using CD-ROM media) or from a server area. You can usually complete an installation in about 5 minutes. If you encounter any failures during installation, see Appendix C.

3.1 Using CD-ROM Software Product Library Media

This procedure loads Compaq C++ files on to a disk belonging to the system where you perform the installation. When Compaq C++ is run, its executable images are mapped into memory on your system.

Follow these steps to install Compaq C++ from CD-ROM media:

1. Mount the media on the appropriate disk drive.
2. Log in as superuser (login name root) to the system where you will install Compaq C++.
3. Specify the /cdrom directory to be the mount point for the distribution file system on the drive. If your drive is ral, enter the following command:

   # mount -dr /dev/ralc /cdrom

4. Enter a setld command that requests the load function (-l) and identifies the directory in the mounted file system where Compaq C++ subsets are located.
   For example, if the directory location for these subsets is /cdrom/cxxnnn/kit, enter the following command:

   # /usr/sbin/setld -l /cdrom/cxxnnn/kit

The installation procedure now displays the names of Compaq C++ subsets and asks you to specify the subsets you want to load.

See Section 3.3 to continue the installation.

3.2 Using a Remote Installation Service Distribution Area

If you are installing Compaq C++ subsets that reside in a /etc/ris Remote Installation Service (RIS) distribution area on a remote system, follow these steps:

1. Log in as superuser (login name root) to the system where you will install Compaq C++.
2. Enter a setld command that requests the load function (-l option) and identifies the system where the Compaq C++ subsets are located. For example, if you are loading Compaq C++ subsets from a RIS distribution area, enter the following:

   # setld -l node:

   
   Replace node: with the node name where the Compaq C++ subsets are located.

RIS now displays a menu that lists all the software subsets available to you and asks you to specify the subsets you want to load.

See Section 3.3 to continue the installation.

3.3 Responding to Installation Procedure Prompts

This section explains the installation procedure prompts and displays.

3.3.1 Selecting Subsets

You must specify which Compaq C++ subsets you want to load by choosing them from a menu or list of subset section options. The number and kinds of subset options you have will vary depending on the version of Compaq Tru64 UNIX you are using. See Section 2.2.

If you specify more than one number at the Choices prompt, separate each number with a space, not a comma.

The installation script (see Appendix A) lets you verify your choice. If you enter a number or numbers in response to the Choices prompt, you will see a display of your choices, preceded by the following:

You are installing the following optional subsets:

You will then be prompted to verify your choice, as follows:

Is this correct? (y/n):

If the displayed subsets are not the ones you intended to choose, enter n. In this case, the subset selection menu is again displayed and you can correct your choice of optional subsets.

If the displayed subsets are the ones you want to load, enter y.

3.3.2 Monitoring Displays During the Subset Loading Process

The installation procedure loads and verifies the selected Compaq C++ subsets.

When you see the "Verifying" message during the subset installation, the installation procedure is checking to see that the files are copied correctly; it is not an Installation Verification Procedure (IVP) message.

During the installation, if you get errors from the setld utility, see the DIAGNOSTICS section of the setld(8) reference page for an explanation of the errors and the appropriate actions to take.

Chapter 4 explains how to run the Installation Verification Procedure (IVP) after installation, and how to delete old Compaq C++ subsets before installing a new version of Compaq C++.

This chapter explains what you need to do after the installation to make Compaq C++ ready for use.

4.1 Running the Installation Verification Procedure

After installing Compaq C++, you can run the Installation Verification Procedure (IVP) independently to verify that the software is available on your system. You might also want to run the IVP after a system failure to be sure that users can still access Compaq C++.

To run the IVP after an installation, enter the following command:

# setld -v subsetname

In this command, subsetname can be any Compaq C++ subset. For a sample Compaq C++ IVP, see Appendix A.

If the verification process fails, look in the /var/adm/smlogs/fverify.log file for information to help diagnose the problem.

4.2 Deleting Compaq C++ from Your System

If you must remove a version of Compaq C++ from your system, delete each subset that you previously installed. To delete subsets:

1. Log in as superuser (login name root).
2. Enter the following form of the setld command:

   # /usr/sbin/setld -i | grep -E CXX | grep installed

3. Delete the installed subsets. For example:

   # setld -d subsetnamennn subsetnamennn

This appendix provides sample listings for the following procedures:

• An installation of Compaq C++ on Compaq Tru64 UNIX Version 4.n using disk media
• An Installation Verification Procedure (IVP) on Compaq Tru64 UNIX Version 4.n

The following listing shows a basic installation of Compaq C++ on a Version 4.0 system using CD-ROM media. For the directory variable, you must supply a disk path name or the directory location posted with the CD-ROM media.

# setld -l CXX620/kit

The subsets listed below are optional: There may be more optional subsets than can be presented on a single screen.

This appendix provides information to help you deal with failures or errors that might occur during product installation or product use.

If you find an error in the documentation, report it to the following Internet address:

cxx_docs@zko.dec.com

Include the title of the document, section and page number where the error occurred.

C.1 Failures During Product Installation

If errors occur during the installation, the system displays failure messages. For example, if the installation fails due to insufficient disk space, a message like the following appears:

There is not enough space for subset subset-name subset-name (subset-description) will not be loaded.

Errors can occur during the installation if any of the following conditions exist:

• The operating system version is incorrect.
• The prerequisite software version is incorrect.
• There is insufficient disk space.
• The system parameter values for successful installation are insufficient.

For descriptions of error messages generated by these conditions, see the Compaq Tru64 UNIX documentation on system messages, recovery procedures, and Compaq Tru64 UNIX software installation. For information on system software requirements, see Section 1.4.3.

Following are error messages you might encounter during installation, along with explanations and suggested corrective steps.

C.2 Failures During Product Use

If an error occurs while Compaq C++ is in use and you believe the error is caused by a problem with the product, please report it to Compaq.

If you have a Software Product Services Support Agreement, contact your Customer Support Center (CSC) by telephone or by using the electronic means provided with your support agreement (such as DSNlink). The CSC provides telephone support for high-level advisory and remedial assistance. When you initially contact the CSC, indicate the following:

• The name and version number of the operating system you are using
• The version number of Compaq C++ you are using
• The hardware system you are using (such as a model number)
• A brief description of the problem (one sentence if possible)
• How critical the problem is

Whether you submit information electronically or contact the appropriate support specialist by telephone, please take the following steps:

1. Describe as accurately as possible the circumstances and state of the system when the problem occurred. Include the description and version number of the Compaq C++ compiler being used. Demonstrate the problem with specific examples.
2. Reduce the problem to as small a size as possible.
3. Remember to include listings of any command files, INCLUDE files, or relevant data files, and so forth.
4. Provide a listing of the program.
5. If the program is longer than 50 lines, submit a copy of it on machine-readable media (diskette or magnetic tape). If necessary, also submit a copy of the program library used to build the application.
   For information about submitting media, see the tar(1) reference page.
6. Report only one problem per report. This facilitates a faster response.
7. Mail the problem report to Compaq.
