IIRC, there's an option --load-max or --max-load or something like that that's
supposed to launch as many jobs as possible up to the max load you specify. I
really doubt this'll work under NT, but it's worth a shot (I've been pleasantly
surprised by Cygwin before).

Subject: RE: Shell spawning and environment problem on W2K
Hi Noel,
Thanks for the e-mails. My cygwin now works correctly and make -j also
works, a little too well though. It has a tendency to run off and spawn
100's of jobs which bring my machine to its knees. I've checked the manual
and it says that -j 2 should restrict to two spawns but it complains about
"jobcontrol process missing" and reverts to one process. Not so good. I
figure this must be a cygwin issue since it works fine on our unix boxes. I
can't find anything in the FAQ yet to prove this or find a workaround. Any
suggestion appreciated. I'll post this on the mailing list and see what
response I get.
Thankyou for your assistance,
Rob

make -j (man make to get the specifics)

Hi All,
Solved. The remaining problem was with the config in our makefile. I
changed something and forgot <embarrassed look>. So it all works now. Time
to get make to run multiple jobs so I can use these two processors on this
new machine, now how do you do that....
TTFN

Hi All,
Okay a bit further along now. Turns out the build script was adding to the
PATH environment variable so that /bin and /usr/bin were no longer first
(third and fourth respectively). Why this made sh.exe a not found I do not
know but there you go.
The second problem with the INCLUDE path environment variable going AWOL is
still kicking around. I'll hunt some more, maybe this is just my new config
and I hadn't notice a few minor changes....

Hi All,
The following doesn't work:
$ make
make: sh.exe: Command not found
make: *** [all] Error 127
The following does sort of:
$ make SHELL=/bin/sh
[ all ] fracviewer-dep
make[1]: Entering directory `/cygdrive/f/bmw/Dev/ft'
cd FracViewer; make fast-dep
make[2]: Entering directory `/cygdrive/f/bmw/Dev/ft/FracViewer'
[snip]
The problem with this version is the environment variables for various
include paths are EMPTY in the build but are defined in the original shell.
It would appear that environment variables are not being passed to the
other processes spawned by make (????).
I've checked the list archive and it seems others have similar problems
with sh in June, July and August. I have just finished re-installing the
latest version from my local mirror, same problem. Unfortunately a solution
was not posted.
What makes it even weirder is I have w2k on two machines. One exhibits the
problem with either an older release or the latest one. The other has the
older release and works fine (I dare not change it to the newer release at
the moment).
Anyone have a clue what's going on?
Rob
