B.3.4.1 Compiling gawk on VMS

To compile gawk under VMS, there is a DCL command procedure that issues all the necessary CC and LINK commands. There is also a `Makefile' for use with the MMS utility. From the source directory, use either:

$ @[.VMS]VMSBUILD.COM

or:

$ MMS/DESCRIPTION=[.VMS]DESCRIP.MMS GAWK

Depending upon which C compiler you are using, follow one of the sets of instructions in this table:

VAX C V3.x

Use either `vmsbuild.com' or `descrip.mms' as is. These use CC/OPTIMIZE=NOLINE, which is essential for Version 3.0.

VAX C V2.x

You must have Version 2.3 or 2.4; older ones won't work. Edit either `vmsbuild.com' or `descrip.mms' according to the comments in them. For `vmsbuild.com', this just entails removing two `!' delimiters. Also edit `config.h' (which is a copy of file `[.config]vms-conf.h') and comment out or delete the two lines `#define __STDC__ 0' and `#define VAXC_BUILTINS' near the end.

GNU C

Edit `vmsbuild.com' or `descrip.mms'; the changes are different from those for VAX C V2.x but equally straightforward. No changes to `config.h' are needed.

DEC C

Edit `vmsbuild.com' or `descrip.mms' according to their comments. No changes to `config.h' are needed.

gawk has been tested under VAX/VMS 5.5-1 using VAX C V3.2, and GNU C 1.40 and 2.3. It should work without modifications for VMS V4.6 and up.
