| 1 | OpenVMS port of Xscreensavser version 2.10 October 1997 |
|---|
| 2 | ========================================== |
|---|
| 3 | |
|---|
| 4 | Xscreensaver distribution can be found in 3 subdirectories: |
|---|
| 5 | |
|---|
| 6 | [.DRIVER] The Xscreensaver and Xscreensaver-command programs. |
|---|
| 7 | [.HACKS] Graphic demos ,can be run either through the xscreensaver program |
|---|
| 8 | or standalone. |
|---|
| 9 | [.UTILS] A small libraries of various utilities. |
|---|
| 10 | |
|---|
| 11 | This port has been tested with VAX VMS 6.1 (compiled with DEC 5 5.0 and |
|---|
| 12 | Motif 1.2) and AXP VMS 6.2 (compiled with DEC C 5.0 and Motif 1.2-4). |
|---|
| 13 | |
|---|
| 14 | To rebuild, you need to rebuild [.UTILS] directory first and create the |
|---|
| 15 | object library (look at the end of COMPILE*.COM procedure). |
|---|
| 16 | |
|---|
| 17 | You can now build the [.HACKS] directory and the [.DRIVER] directory. |
|---|
| 18 | |
|---|
| 19 | A one-step build is now available via the MAKEVMS.COM script. |
|---|
| 20 | |
|---|
| 21 | WARNING : before building [.HACKS], you may need to correct some of the |
|---|
| 22 | DECwindows bitmap files. Some files are bogus !! (they have a long line of |
|---|
| 23 | null chars at the end). These files are under |
|---|
| 24 | SYS$COMMON:[DECW$INCLUDE.BITMAPS] directory: |
|---|
| 25 | |
|---|
| 26 | STIPPLE.XBM |
|---|
| 27 | HLINES2.XBM |
|---|
| 28 | LIGHT_GRAY.XBM |
|---|
| 29 | ROOT_WEAVES.XBM |
|---|
| 30 | VLINES2.XBM |
|---|
| 31 | |
|---|
| 32 | These files are all used by Greynetic demo. |
|---|
| 33 | |
|---|
| 34 | Nota: link procedure automagically select appropriate X and Motif Libraries |
|---|
| 35 | (X11R4/Motif 1.1 - X11R5/Motif 1.2). |
|---|
| 36 | |
|---|
| 37 | The SETUP.COM procedure gives you a definition of all DCL foreign command |
|---|
| 38 | symbols needed to run Xscreensaver and all the graphic hacks. You need to |
|---|
| 39 | modify this procedure if you install these programs in another directory tree. |
|---|
| 40 | |
|---|
| 41 | You can easily add new graphic demos without recompiling Xscreensaver. You just |
|---|
| 42 | need to add them in resource file XSCREENSAVER.DAT. This file (originally |
|---|
| 43 | present in [.DRIVER] directory ) can be installed under your SYS$LOGIN |
|---|
| 44 | directory for a per-user customization basis. You can also install it under |
|---|
| 45 | the system-wide user resource directory SYS$COMMON:[DECW$DEFAULT.USER] |
|---|
| 46 | (with (W:RE) protections). The new graphics hack must be run in root-window |
|---|
| 47 | mode to be accepted by Xscreensaver. |
|---|
| 48 | |
|---|
| 49 | The graphic demos are spawn into subprocess created by the system() call (in |
|---|
| 50 | the Unix version the execvp() call is used). |
|---|
| 51 | |
|---|
| 52 | The VMS passord checking programs were picked up in the Xlock distribution. |
|---|
| 53 | |
|---|
| 54 | Enjoy, |
