Comedi has a mailing list. Send "subscribe comedi" to majordomo@stm.lbl.gov to subscribe. If you are upgrading from a previous version, see the upgrade notes below. Compile using 'make'. If this doesn't work, make sure you have the basic tools installed to compile. If you can successfully compile other things, consult the author, as he has probably made a mistake. Install using 'make install' as root. This installs the files: /usr/lib/libcomedi.so.0.3 /usr/include/comedi.h /usr/include/comedilib.h and other things... To write programs that use comedi, look at examples in the demo/ and the documentation in the doc/ directory.
