Problem with BASH


Hey,
I am trying to create a LFS system on my computer. Right now, I am at the point where I chroot into the temporary system. The only problem is that BASH doesn't work correctly. When I enter something at the prompt, like 'ls', it executes the command and shows the results, but doesn't show a new prompt afterwards. I tried recompiling bash, but without success.
Does anyone what an idea of what might be wrong?

thanks!

Pheidon

What was your host environment? What happens when you type expect -c "spawn ls"?

My host enviroment is SuSE 9.2.
Well, all that does in my host enviroment is echo the words "spawn ls", but if I type it in the chroot'ed shell, I get:
"spawn ls
The system has no more ptys. Ask your system administrator to create more.
while executing
"spawn ls""
and no more prompt.

If I run the shell of my chroot'ed enviroment ( /tools/bin/bash) and enter "expect -c "spawn ls"" there, I get an echo, but no new prompt.

Any ideas on what went wrong?

thank you!

I figured that was the problem, try one of these solutions:

thank you for the suggestions!
I tried them, but they didn't work

I have enough ptys in the host enviroment, but not in the chrooted enviroment
Code:
 
linux:/home/seabass # expect -c "spawn ls"
spawn ls
linux:/home/seabass # ~lfs/start.sh
mount: proc already mounted or /home/lfs/lfs/proc busy
mount: according to mtab, proc is already mounted on /home/lfs/lfs/proc
mount: sysfs already mounted or /home/lfs/lfs/sys busy
mount: according to mtab, sysfs is already mounted on /home/lfs/lfs/sys
root:/# expect -c "spawn ls"
spawn ls
The system has no more ptys.  Ask your system administrator to create more.
    while executing
"spawn ls"
After the last message, the "root:/#" prompt fails to return, forcing me to close the shell.
