/usr/bin/env: perl^M: No such file or directory

[ckerry]

Hello,
When I compile I get the following error.

Clean previous scratch build
svn: E155007: '/scale_wlg_persistent/filesets/project/mocean03108/roms_src/trunk' is not a working copy
svn: E155007: '/scale_wlg_persistent/filesets/project/mocean03108/roms_src/trunk' is not a working copy

make: *** No rule to make target `/home/ckerry/OSSEs/Truth/compiling_new/build/MakeDepend', needed by `all'. Stop.

The first line of the file ./roms_src/trunk/ROMS/Bin/sfmakedepend was #!/usr/bin/env perl, however on my server perl is in #!/usr/bin/, so I changed this line to #!/usr/bin/ perl

However I still get the error: /usr/bin/env: perl^M: No such file or directory
Why is it looking in /usr/bin/env? This directory doesn't exist. And what does the ^M mean?

Thanks for your help

This would indicate that you checked out the ROMS source code on a Windows machine then tried to build it on a non-Windows system. The '^M' is how Windows (DOS actually) style line endings/carriage returns are interpreted by non-Windows systems.

Ahh OK thank you.
I did this as the Gui was so much easier, then I copied to the Linux machine. Which I now realise is incorrect.

I have now downloaded the code from the terminal and checked out the required version, and all is compiling well. Thank you.
