B.3.2.1 Compiling gawk on OpenVMS

To compile gawk under OpenVMS, 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 and MMK utilities. From the source directory, use either:

$ @[.vms]vmsbuild.com

or:

$ MMS/DESCRIPTION=[.vms]descrip.mms gawk

or:

$ MMK/DESCRIPTION=[.vms]descrip.mms gawk

Note that the vmsbuild.com method of building is no longer being maintained and is planned to be removed in the future.

MMK is an open source, free, near-clone of MMS and can better handle ODS-5 volumes with upper- and lowercase file names. MMK is available from https://github.com/endlesssoftware/mmk.

With ODS-5 volumes and extended parsing enabled, the case of the target parameter may need to be exact.

gawk has been tested using these VMS Software, Inc. Community editions:

• HP C V7.3-010 on OpenVMS Alpha V8.4-2L1.
• HP C V7.3-020 on OpenVMS IA64 V8.4-2L3.¹¹⁷

Due to HPE cancelling the Hobbyist licensing program, no more testing is being done on older releases of OpenVMS.

See The OpenVMS GNV Project for information on building gawk as a PCSI kit that is compatible with the GNV product.
