System name: pickled-herring
Type and version: POWER 7.7F (1 update(s) to same version)
Display type: POWER_Gt1
What were you trying to do?
Run gcc from the cygnus locker with a nonstandard PATH.
What's wrong:
1] It fails to find machtype. /mit/cygnus-94q2/common/scripts/gcc,
also known as /mit/cygnus/{rsaix,sun4,decmips}bin/gcc. For instance:
% echo $PATH
/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin
% /mit/cygnus/rsaixbin/gcc -v
Can't exec "machtype": No such file or directory at /mit/cygnus/rsaixbin/gcc line 41.
GCC_DEFAULT_OPTIONS=
gcc version cygnus-2.5.90-940429
2] Ted is broken.
What should have happened:
1] The line that reads:
$machtype = `machtype`; chop $machtype;
should read:
$machtype = `/bin/athena/machtype`; chop $machtype;
resulting in having gcc work. It should be noted that this is a bug
for all 3 athena platforms. It has been suggested to me by an
over-the-shoulder reader that it is reasonable to attempt
to invoke machtype prior to /bin/athena/machtype; I think this
is unnecessary, but it certainly acceptible.
2] Shoot Ted.
More specifically, per the comments:
# 94/01/13 tytso Converted script to perl, so that shell metacharacters
# in gcc's command line don't get hosed.
Ted converted this script to perl. *HOWEVER*, the construction
he uses in perl:
exec("$0.real", @ARGV) || die "Can't run $0.real: $!\n";
Can be replaced by the Bourne shell construction:
$0.real {$1-"@$"}
Which is a less-than-commonly-known, portable, construction.
Please describe any relevant documentation references:
1) The thread, "mosaic outputs cruft to stdout" in the bug-sipb
discuss meeting on bloom-picayune, consisting of transactions
[4984] [4986] [4987] [4988] [4992] [4993] [4994] [4995] [4996]
[4997] [4998] [4999], where the above was recently demonstrated.
2) PERL CONSIDERED HARMFUL, a work in progress, by John A. Hawkinson.
Please send requests to perl-considered-harmful-request@panix.com.
3) Ted is supposed to be at IETF in San Jose next week; if you don't
catch him before he goes, you might ask one of the following
MIT people to shoot him for you:
55 Berners-Lee, Tim Massachusetts Institute of Technology
139 Clark, David Massachusetts Institute of Technology
200 Eichin, Mark Cygnus Support
322 Horowitz, Marc OpenVision Security Business Unit
426 Linn, John OpenVision Technologies
638 Schiller, Jeffrey Massachusetts Institute of Technology
674 Sollins, Karen Massachusetts Institute of Technology
719 Ts'o, Theodore Massachusetts Institute of Technology
773 Wroclawski, John Massachusetts Institute of Technology
Barring the above, shooting a real-time image of Ted over the
MBONE real-time is permissable; channels are:
IETF Channel 1 Video 224.0.1.12 4120 0
IETF Channel 2 Video 224.0.1.15 4150 0
4) As far as I know, Ted is not an Athena supported program
(/mit/tytso/README.athena is nonexistant, as is
/afs/net/user/tytso/README.athena, as is
/afs/sipb/user/tytso/README.athena. As an aside,
/mit/tytso/README.serial does not discuss the serial nature
of Ted, nor the serial shooting of him); as such, certain
parts of this bug report, though intend to be humorous, may
not be whoally appropriate to this forum.
