Penguinbrain v2.8 doesnt work

[c1u66y]

Hello together,

i have some issues with Penguinbrain. For them, who dont know this program, its a training program for the LPI 1 & 2.

Here is a strace of penguinbrain under gutsy:

Now, i think the problem is in line 28:

execve(""", ["./penguinbrain"], [/* 37 vars */]) = -1 ENOENT (No such file or directory)

Can anyone tell me, why in gutsy the file "/proc/26546/fd/3" is closed but not in dapper?

Thanks in advance.

Re: Penguinbrain v2.8 doesnt work

I would suggest contacting the software company. I would venture a guess that there are some newer libraries in Gutsy than those used to compile or build the program's executable, and since there is no source code, we can't build it for ourselves.
