Compiling WorkMan for Solaris 2
WorkMan should compile without modification on Solaris 2.x, provided
you make sure the three relevant lines indicated in the Makefile are
uncommented. The LIBLOC line is necessary to get it to run properly in
conjunction with the volume manager (vold) found in Solaris 2.2 and
later.
If you're using the SPARCworks compilers from Sun, make sure your
search path is set so that "/opt/SUNWspro/bin" (or whatever directory
the compilers are in) is searched before "/usr/ucb". Otherwise you'll
be using a different set of libraries and include files, and WorkMan
won't compile properly.
If you get a message like "language optional software package not
installed," your machine probably does not have SPARCworks, and you
should talk to your system administrator about getting gcc.
Using gcc
You should be able to compile WorkMan using gcc. Just uncomment the
"CC=gcc" line in the Makefile and comment out (or remove) "CC=cc".
Gcc version 2.6.0 is known to compile WorkMan on Solaris 2.4 without
any special handholding; older versions of Solaris and/or gcc
apparently have some trouble with the include files in
/usr/openwin/include. If you get compiler errors about OpenWindows
include files, you should probably run the "fixincludes" utility that
comes with gcc, giving it the correct command line arguments so it
fixes /usr/openwin/include.
Using the volume manager
If you're running the volume manager -- you probably are -- you can
get it to start WorkMan when you insert a music CD. Assuming you've
installed WorkMan in /usr/openwin/bin, add the following line to
/etc/rmmount.conf, _before_ the action_filemgr line:
action cdrom action_workman.so /usr/openwin/bin/workman
You should already have "action_workman.so" -- it comes with Solaris.
With that line in place, a WorkMan window should appear on your screen
when you insert a CD.
Note that the volume manager doesn't know whether you're running a
window system, so if you put in a music CD when you're not running
OpenWindows (or there's one in the drive when the system boots up)
you'll have to eject it with the "eject" command and reinsert it to
get the WorkMan window to appear.
Also, WorkMan will be running as root or as nobody, not as you, since
the volume manager runs without regard to who happens to be logged in
on the console. As a result, you'll probably want to edit your
.Xdefaults file and add the "workman.db.shared" and
"workman.db.personal" resources to tell WorkMan where to find its
database files. For example, if /users/jane is your home directory,
you'd probably add:
workman.db.shared: /users/jane/.workmandb
workman.db.personal: /users/jane/.workmanrc
Then run "xrdb -merge $HOME/.Xdefaults" to load the new settings into
your X server. You should only have to run that command once;
.Xdefaults is read automatically when you start the window system.
If you do use the volume manager to start WorkMan, you may find you
have to run "xhost hostname" (where hostname is the name of your
machine) to give root-owned processes the right to connect to your X
server.
You'll also find that setting environment variables has no effect on
WorkMan when it's started by the volume manager, even if you set them
before you start the window system. To see why, realize that
environment variables are inherited by new processes from their
parents. The volume manager is started at system boot time, before
you've logged in; it's what runs WorkMan, so WorkMan only gets
whatever variables were set when vold was started. Setting variables
in your .cshrc, or manually in a window, does not magically cause them
to be set in preexisting processes or those processes' children.
Avoiding the volume manager
If all that sounds too confusing and you'd like to avoid the volume
manager altogether, you can start WorkMan by hand as long as you do it
after you've inserted a CD.
Getting audio output from the workstation
(Note: This section only applies to the SPARCstation 5, and possibly
the 20. On other machines, hook up a cable from the CD player's
headphone jack to the computer's microphone input.)
Version 1.3 of WorkMan adds code to control the audio hardware on the
SS5. It only works if there is a physical connection inside the
machine between the CD player's internal audio output and the internal
audio input on the workstation. Instructions for making that
connection are included with the CD-ROM drive; don't ask me.
The code was added by <stevep@ctc.ih.att.com>, who has this to say:
I'm sure there will be problems with it, as people use hardware
configurations I didn't imagine. I'll be happy to try to deal with
them.
The use of audiocontrol, audiotool, gaintool, or the like in
conjunction with this is highly recommended. Upon initialization,
it switches the codec input to the internal CD player, and turns
the monitor gain up to full (necessary). Thereafter, anytime
WorkMan begins a play operation, it checks the state of the codec
and enforces the following conditions:
channels: 2
encoding: linear
precision: 16 bits
sample rate: 44100
monitor gain: max
input port: internal cd player
It does NOT "own" /dev/audio, nor does it check state other than
when beginning a "play". This allows other processes to do things
with the audio system. Please note that most other things will
leave the chip in a relatively pathetic state (8-bit ulaw mono at
8000 samples/sec); pausing and resuming will correct this.
This all comes about because the headphone jack on the CD drawer
sounds awful (lots of processor noise; apparently, Sun doesn't
believe in shielding). The headphone jack out the back sounds MUCH
better, but one has to go through the audio chip to get there.
Please send mail directly to him if you have problems with this aspect
of WorkMan.
