Hi,
I'm currently trying to get Linux working on an embedded sparc processor
(leon3, sparc V8).
But every time I try to run an instance of bash the following error occurs:
sh-3.2# bash
bash: command_substitute: cannot duplicate pipe as fd 1: Bad file descriptor
(currently I'm using bash as init)
This software is used:
bash-3.2_p39
gcc-4.2.1
uClibc-0.9.30
linux-2.6.21.1
In my opinion this problem might not be bash related, but I have no idea
what goes wrong. Unfortunately gdb seems to rely on some shell functions, so
I can't use it.
No idea if this is helpfull: here is the end of strace's output:
open("/etc/passwd", O_RDONLY) = 3
ioctl(3, TCSETAF or SNDCTL_TMR_SELECT, 0xefc669c4) = -1 ENOTTY
(Inappropriate ioctl for device)
brk(0xcc000) = 0xcc000
read(3, "root:x:0:0:root:/root:/bin/bash\nb"..., 4096) = 704
close(3) = 0
stat64("/", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64(".", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
getpid() = 659
getppid() = 658
ioctl(2, TCSETAF or SNDCTL_TMR_SELECT, {B38400 opost isig icanon echo ...})
= 0
brk(0xcd000) = 0xcd000
open("/etc/bash/bashrc", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=2550, ...}) = 0
read(3, "# /etc/bash/bashrc\n#\n# This file "..., 2550) = 2550
close(3) = 0
brk(0xce000) = 0xce000
stat64("//.dir_colors", 0xefc665c0) = -1 ENOENT (No such file or
directory)
stat64("/etc/DIR_COLORS", {st_mode=S_IFREG|0644, st_size=4038, ...}) = 0
pipe([3, 4]) = 3
fork(bash: command_substitute: cannot duplicate pipe as fd 1: Bad file
descriptor
) = 660
Thank you for your help.
