Configure Issue

[kk2202]

I am new to linux. Learning things as I am working on the project,

I have a ./configure executable. I find that it has been obtained using the configure.ac file. Can any one explain how this configuration executable is created ?

I get the following error when i try to run the ./configure
bash-3.2$ ../configure
bash: ../configure: /bin/sh^M: bad interpreter: No such file or directory

Any pointers or guidelines on some tutorials, if this was very simple issue , will be highly useful.

First ensure that it is executable.
Then cd into the directory where the file is and run it as follows;

./configure

Notice the single '.' not a double.

The first line in a configure script is the shell intended to execute the code it contains. Your's has specified to use /bin/sh, but your system doesn't seem to have that file. It may be in /usr/bin or not there at all (unlikely, but possible). Go to a command-line window and execute the command: which sh
That will show you where (if found) the standard shell (sh) is located. If it isn't in /bin/sh but exists, then you can either change the configure script to point to the correct location, or you can copy it to /bin as root.
