Hi-
This is a follow-up to the situation:
1) upon further review, both Matlab 5.2 and 5.3 fail in the same
way with linux_base-6.1 and 4.0 circa the RELEASE
2) both matlab binaries have
/tmp/MLsystem%ld
hardcoded into them. The error is
>> helpdesk
To learn how to configure your Web browser type 'help docopt'
sh: /tmp/MLsystem23714: Permission denied
if /compat/linux/tmp does not exist. creating it certainly
solves the problem, but could lead to confusion over the
meaning of /tmp.
It would seem that the path lookup/mapping is failing here. I
have tried this w/ and without
#! /compat/linux/bin/sh
in both the matlab script and the matlabdoc script. It made no
difference.
Any further ideas?
A quick look through a ktrace under linux_kdump shows that it
is /compat/linux/bin/sh (bash) returning the error.
