dpkg-checkbuilddeps: error: could not read debian / control: No such file or directory

@nkp216 Sorry for the slow reply. My guess is that you do not have git installed, which the script requires to download the source. You can install git by running sudo apt-get install git

Thanks for your comment!

dpkg-checkbuilddeps checks the installed packages in the system .
By default, debian/control is read.
But there are no files debian/control in the sources (https://github.com/LinuxCNC/linuxcnc/tree/master/debian)

but here it is already there (http://buildbot.linuxcnc.org/dists/precise/master-rt/source/)
Without it, the script does not work(for me)
ps
sorry for the font (for some reason it is not editable)

added this line :
find . -type f -not -path '*/\.*' -exec grep -Il '.' {} \; | xargs -d '\n' -L 1 dos2unix -k
It works now , thanks!
