- README file for gzip on VMS
- written by Klaus Reimann <kr@cip.physik.uni-stuttgart.de>
-
- Here is a list of the files in [.vms]:
-
- GZIP.HLP ! Help-file, how to use gzip
- MAKEFILE.GCC ! Description for (vms-)make, using gcc
- MAKEFILE.MMS ! Description for MMS-utility, using vaxc
- MAKEFILE.VMS ! Description for (vms-)make, using vaxc
- MAKEGZIP.COM ! simple and robust DCL-Script, using vaxc
- README.VMS ! this file, how to install gzip
- VMS.C ! VMS-specific functions in gzip
-
- This file describe, how to compile and install the VMS-Port of gzip.
- >>For restrictions or bugs due to the structure of the vms-filesystem
- refer to gzip.hlp.<<
-
- Installing gzip
-
- Since there are many makefiles there are many possibilities
- compiling and installing gzip. For most of them, it is important,
- that you start them from the SOURCE-Directory (that is where
- gzip.c is), not from the [.vms]-directory. Otherwise the compiler
- won't find the source-files.
-
- Using gcc saves disk-space, but needs longer to compile
- VAXC gzip.exe 95/96 Blocks
- gcc2.3.3 gzip.exe 86/87 Blocks
-
- To install gzip one has to perform the following steps:
- 1. compile sources (*.c, [.vms]*.c)
- 2. link executable gzip.exe
- 3. Make entries gunzip.exe and zcat.exe to gzip.exe.
- These are similar to hardlinks in UNIX
- >>If You wish to do this by hand, see for example makegzip.com.<<
- The Entries can't be simply deleted, use 'set file /remove' .
-
- 4. Rename executables (*.exe) to Your prefered exe-directory. If it is on
- another Device, then you should only copy gzip.exe and do the
- entries gunzip.exe and zcat.exe by hand (3.).
-
- 5. Setting up Symbols for the executables:
- Place the following lines in Your login.com
- Change "disk:[directory]" as appropriate.
- $ gzip == "$disk:[directory]gzip.exe"
- $ gunzip == "$disk:[directory]gunzip.exe"
- $ zcat == "$disk:[directory]zcat.exe"
- 6. insert help-file gzip.hlp in any Help-library,
- for example in sys$help:helplib.
- this can be done by $lib sys$help:helplib/help gzip
- (I did not try this command)
-
- Steps (4.)5. through 6 must be done by hand.
- Steps 1 through 3(4.) may be done by one of the makefiles:
-
- a) MAKEGZIP.COM
- This was crated from MAKEFILE.VMS and later on edited. It uses the
- VAXC-Compiler and does compiling, linking and making the entries.
- Usage:
- - change to the Source-Directory
- - copy vms.c
- $copy [.vms]vms.c []
- - start compiling, linking, entries
- $@[.vms]makegzip
- if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
- continue at Step 4.
-
- b) MAKEFILE.VMS
- Makefile for a vms-make utility (NOT gnu-make).
- Is uses the VAXC-Compiler and has the Advantage over MAKEGZIP.COM
- that make checks dependencies. This is helpfull if You have to
- recompile several times, for example after editing the sources.
- - change to the Source-Directory
- - copy vms.c
- $copy [.vms]vms.c []
- - start compiling, linking, entries
- $make /input=[.vms]makefile.vms
- if everything is OK. then you get gzip.exe, gunzip.exe, zcat.exe
- Continue at Step 4.
-
- c) MAKEFILE.GCC
- Same as MAKEFILE.VMS, but uses gcc
- - Use $make /input=[.vms]makefile.gcc instead of make ....
-
- d) MAKEFILE.MMS
- Makefile for the MMS-utility. Similar to MAKEFILE.VMS
- - Use $mms /description=[.vms]makefile.mms instead of make ....
