Description Need Real Name 2000-10-02 14:30:45 UTC
After installing RH7 (Deluxe), I tried installing Matlab 5, which worked
fine under all previous versions of Linux.  However, after installing, I
get the message 

/usr/local/matlab5/bin/lnx86/matlab: No such file or directory

which is very strange since that file exists.  Even cd'ing into that
directory and doing ./matlab still gives me the "No such file..." error
even though I chmod'd +777 it (and tried the command as root).  A similar
thing happened on the installation of Matlab since it could not find a
file xsetup (even though it was on the CDROM), but I got around that using
a text install.  

Now, the point is that I strongly believe this is *not* a Matlab problem,
but a problem of Linux since even if the file was completely screwed up,
doing ./matlab would still give back some other error message than "No
such file..."   Of course, I also tried adding . to my PATH too.  That did
not help.

(By the way, I selected bash as the component, since I could not think of
what could cause this.)

Comment 1 Bernhard Rosenkraenzer 2000-10-02 14:43:14 UTC
By any chance, is /usr/local/matlab5/bin/lnx86/matlab a script?
If you try to execute a script that requires a shell that doesn't exist (i.e. a
script that starts with "#!/bin/my-nonstandard-shell"), it should and will
generate "File not found".

Please add the output of "head -n5 /usr/local/matlab5/bin/lnx86/matlab"

Comment 2 Need Real Name 2000-10-02 14:55:38 UTC
No, this is definitely *not* a script.  head ... gives

            4 (tse44?4?  cbTT?T?rrc``??dy
P]P]xxec/lib/ld-linux.so.1  a


(and some more stuff like that).  It is an executable file.  

However, as I said before it should not matter what kind of file this is. As
long as it's executable, *something* should happen, but definitely not a "No
such file..." error.

Comment 3 Bernhard Rosenkraenzer 2000-10-02 14:58:35 UTC
Wrong guess, same reason: The header shows it wants /lib/ld-linux.so.1 - this is
libc5 stuff.
We no longer support libc5.

If you need to run it, install the libc5 compat packages (libc and ld.so) from

Comment 4 Need Real Name 2000-10-04 00:46:56 UTC
May be it should give to the user some indication of the real cause of the error
... and certainly not say "File not found ....!!!"
