Open Watcom C/C++ Version 1.9 - README
|
||
|
|
--------------------------------------
|
||
|
|
|
||
|
|
Welcome to the Open Watcom C/C++ version 1.9 release! This README provides
|
||
|
|
helpful hints to help you get the software package up and running. For more
|
||
|
|
detailed information on installation and setup, please refer to online
|
||
|
|
Getting Started Guide (c_readme.hlp/c_readme.inf).

===========================================================

|
Important
|
||
|
|
===========================================================
|
||
|
|
|
||
|
|
Some Open Watcom tools currently do not function properly if installed in a
|
||
|
|
directory with spaces in the name e.g. "C:\Program Files\WATCOM".
|
||
|
|
Therefore choose a directory name like C:\WATCOM, D:\WATCOM etc. to install
|
||
|
|
the tools in.
|
||
|
|
|

|
|
Environment variables used by Open Watcom
|
||
|
|
===========================================================
|
||
|
|
|
||
|
|
For proper operation the Open Watcom compilers require few environment
|
||
|
|
variables to be set up correctly. These variables differ slightly depending
|
||
|
|
on the host platform (DOS, OS/2, Win32). The common variables are:
|
||
|
|
|
||
|
|
- PATH - points to directories containing Open Watcom executables
|
||
|
|
- WATCOM - points to the directory where Open Watcom is installed
|
||
|
|
and is used by various Open Watcom tools to locate files
|
||
|
|
- EDPATH - points to VI/VIW configuration files
|
||
|
|
- INCLUDE - points to directories containing header files used by the
|
||
|
|
C/C++ compilers
|
||
|
|
- LIB - points to directories containing library files; note that
|
||
|
|
Open Watcom linker is able to locate Open Watcom runtime
|
||
|
|
libraries without this variable
|
||
|
|
- WWINHELP - points to the directory on the CDROM drive where help files are
|
||
|
|
located. This may minimize hard disk space requirements
|
||
|
|
|
||
|
|
DOS specifics
|
||
|
|
|
||
|
|
- PATH - only needs to point to the binw directory
|
||
|
|
- WWINHELP - points to the directory on the CDROM drive where help files
|
||
|
|
are located. This minimizes hard disk space. Note this is not
|
||
|
|
needed if the help files are installed on the hard disk
|
||
|
|
|
||
|
|
Win16 specifics
|
||
|
|
|
||
|
|
- PATH - only needs to point to the binw directory
|
||
|
|
- WWINHELP - points to the directory on the CDROM drive where help files
|
||
|
|
are located. This minimizes hard disk space. Note this is not
|
||
|
|
needed if the help files are installed on the hard disk
|
||
|
|
|
||
|
|
Win32 specifics
|
||
|
|
|
||
|
|
- PATH - must point to binnt and binw directories, in that order
|
||
|
|
- WWINHELP - points to the directory on the CDROM drive where help files
|
||
|
|
are located. This minimizes hard disk space. Note this is not
|
||
|
|
needed if the help files are installed on the hard disk
|
||
|
|
|
||
|
|
OS/2 specifics
|
||
|
|
|
||
|
|
- PATH - must point to binp and binw directories, in that order
|
||
|
|
- LIBPATH - either the BEGINLIBPATH/ENDLIBPATH environment variable or the
|
||
|
|
LIBPATH statement in CONFIG.SYS must point to the binp\dll
|
||
|
|
subdirectory of Open Watcom in order to let the OS find
|
||
|
|
Open Watcom DLLs
|
||
|
|
- HELP - points to binp\help to let Open Watcom GUI tools locate online
|
||
|
|
help files
|
||
|
|
- BOOKSHELF - points to binp\help to allow the IPF viewer (VIEW.EXE) locate
|
||
|
|
Open Watcom online manuals
|
||
|
|
|
||
|
|
These environment variables can be either set up in your startup files (which
|
||
|
|
is the most convenient method if Open Watcom is the only compiler you use)
|
||
|
|
or you can use simple batch files to set these variables (useful if you
|
||
|
|
need to switch between compilers, including different versions of
|
||
|
|
Watcom/Open Watcom compilers).
|
||
|
|
|
||
|
|
Below are several sample batch files for setting the environment variables on
|
||
|
|
various host platforms. The WATCOM variable must naturally be adjusted
|
||
|
|
according to where Open Watcom was installed on your system. The LIB
|
||
|
|
environment variable isn't strictly necessary but you will probably need
|
||
|
|
to set it for any libraries you use not supplied with Open Watcom compilers.
|
||
|
|
Similarly you might need to adjust the INCLUDE variable for 3rd party
|
||
|
|
library include files.
