[aclug-L] Re: Program needs libm.so.5

["kai & steven Hallacy" <enginear@xxxxxxxxx>]

I didn't create the program.  The program, called Nserver, comes
from www.robots.com.  I'm using the program to simulate a super
scout 2 robot for my ECE738 (Embedded Systems).  I've been
speaking to a person at www.robots.com and he hasn't repied to my
email message since yesterday.

First, I tried the most current version of Nserver.  Running the
current version resulted in a segmetation fault.
Next,  I called the support group at www.robots.com and got in
touch with Jake.  Shown below is the email conversation between
Jake and I.   Yesterday, I called him and he told me to use a
previous version of Nserver.   The previous version of the
program has problems finding the libraries.

Jake,

This message contains an file attachment which has the listing of
the /usr/lib directory.

Steven,

Is the write-protect tab of your floppy disk set?

Another thing you can try is using the mtools to access your
floppy drive
-- e.g. `mdir` is the equivilant of the DOS DIR command, and
mwrite will
copy files to the floppy.  You can use these without the floppy
drive
being a mounted filesystem.
