Configuration: error: cannot start / bin / sh

Question

I am trying to create the GNU program chain for OpenRISC by following the guide given at http://openrisc.net/toolchain-build.html in the Fedora virtual box.

I get an error

Configure: error: cannot run /bin/sh ../gcc-svn/config.sub

when i try to configure gcc.

I am new to Linux. I could not find any solution on the Internet. Any help to solve the problem is much appreciated.

Answer 1

1.check and install libtools

yum install libtool       
yum install libtool-ltdl    
yum install libtool-ltdl-devel       

2. run the run "../gcc-svn/config.sub" through the shell

/bin/bash ../gcc-svn/config.sub

see if the following is displayed:

[root @centos jemalloc] #/bin/ bash./config.sub

'/config.bub: 88: `case $1 in

3. config.sub

 find / -name config.sub

mv ../gcc-svn/config.sub ../gcc-svn/config.sub.bak
cp /usr/share/libtool/config/config.sub ../gcc-svn/config.sub 

mv ../gcc-svn/config.guess ../gcc-svn/config.guess.bak

Answer 3

/bin/sh

#!/bin/sh

Make sure the / bin / sh file exists and is executable

ls -l /bin/sh

Gotta show something like

-rwxrwxrwx 1 root root 4 Feb  3  2009 /bin/sh
