Building Comedi from CVS is slightly different from the releases. There is an additional step of creating the configure script and makefiles from the templates using automake, autoconf, etc. This is all done automatically by running the script ./autogen.sh. You may need to edit the autogen.sh script so that it runs the appropriate commands. Often, the necessary commands have version suffixes. Occasionally, for strange reasons, errors can be solved by running ./autogen.sh twice. Requirements: automake >= 1.6 autoconf >= 2.54
