Hello, I am trying to package a library that contains some cython code in a ./src folder. I am using this rules file: http://bazaar.launchpad.net/~pythonxy/pythonxy-upstream-debian/python-fiona_debian/view/head:/rules But my Launchpad builds always fail. Could someone please help me or provide me tip on how to prepare the corresponding rules for correct building? Thanks a lot in advance and kind regards, Timmie
