Previously installed products may have set environment variables that need to be unset. Please check the list below for such products:
- If you have installed IBM Visual Age C++ for OS/2, Version 3.0:
When you install IBM's VisualAge C++ for OS/2, Version 3.0, it installs other OS/2 products as well. For instance, a version of IBM SOMObjects 2.1 is installed, and a version of the OS/2 Developer's Toolkit is installed.
The installation of IBM Visual Age C++ for OS/2 probably created changes to several important environment variables in your CONFIG.SYS file:
This edition of OpenDoc installs a more current version of parts of the IBM SOMObjects 2.1 runtimes and of the OS/2 include files and lib files from the OS/2 Developer's Toolkit. It will attempt to update or correct the environment variables shown above. In general, after installing OpenDoc, you will no longer need references to %CPPMAIN%\include\OS2 in your make files or in the INCLUDE environment variables. You will no longer need references to %CPPMAIN%\lib\OS2 in your makefile or in the LIB environment variables.
The SOM include files and SOM runtimes are part of the code
installed with this version of OpenDoc. They are more current
than what was shipped in the 3.0 version of the IBM Visual Age C++ for OS/2 product or in its CSDs. You will need to remove references to any %CPPMAIN%\*\SOM
directories from your PATH
or LIBPATH
environment variables.
Be careful to observe the above ordering of files.
- If you have installed SOMObjects 2.1 for OS/2:
The installation of IBM SOMObjects 2.1 for OS/2 probably created changes to several important environment variables in your CONFIG.SYS file:
- SOMBASE
- LIBPATH
- PATH
- SOMIR
This edition of OpenDoc installs more current versions of parts of the IBM SOMObjects 2.1 runtimes and OS/2 include files and lib files from the OS/2 Developer's Toolkit. It attempts to update or correct the environment variables shown above. In general, after installing OpenDoc, you no longer need references to %SOMBASE%\include\ in your make files or in the INCLUDE environment variables. In addition, you no longer need references to %SOMBASE%\lib\ in your makefile or in the LIB environment variables.
Remove any references to paths that start with the
directory named by %SOMBASE%
from your LIBPATH and PATH statements before you begin to install this version of OpenDoc.
- If you have installed an OS/2 Developer Toolkit:
The installation of an IBM OS/2 Developer Toolkit probably created changes to several important environment variables in your CONFIG.SYS file:
This edition of OpenDoc installs more current versions of parts of the IBM SOMObjects 2.1 runtimes and OS/2 include files and lib files from the OS/2 Developer's Toolkit. It attempts to update or correct the environment variables shown above. In general, after installing OpenDoc, you no longer need references to the include Toolkit directory in your make files or in the INCLUDE environment variables. In addition, you no longer need references to the lib Toolkit directory in your makefile or in the LIB environment variables.
Examine any references to paths that start with the
directory named by the Toolkit in your LIBPATH and
PATH statements, before you begin to install this version of OpenDoc. You do not need any SOM or OS/2 header or lib information from the Toolkit.
