• Installation instructions

Installing COMEDI

• Installation on Ubuntu

Generic instructions

1. Compile the kernel modules
   1. "su"
   2. "cd /usr/src"
   3. Download linux-2.6.x.tar.bz2 from www.kernel.org
   4. "bzip2 -d -c linux-2.6.x.tar.bz2 | tar x"
   5. "cd linux-2.6.x"
   6. "make menuconfig". Choose "Load an Alternate Configuration File" and import your old kernel config. If you are compiling the first time you can probably import it from /boot.
   7. "make bzImage modules modules_install" and copy your bzImage to /boot (e.g.: "cp arch/i386/boot/bzImage /boot").
   8. Tell the boot loader that there's a new kernel ("/etc/lilo.conf" or "/boot/grub/menu.lst"). If you've got lilo don't forget to run it.
   9. reboot
   10. Download comedi.tar.gz.
   11. Unpack with "tar xzvf comedi.tar.gz".
   12. "cd comedi"
   13. "./configure"
   14. "make"
   15. "su"
   16. "make install"
   17. "depmod -a"
2. Compile/Install comedilib (userspace)
   1. Download: comedilib.tar.gz
   2. "tar xzvf comedilib.tar.gz"
   3. "cd comedilib"
   4. If you've downloaded from the cvs type: "sh autogen.sh"
   5. 1. For old hotplug: "./configure --enable-etc-hotplug --sysconfdir=/etc"
      2. For new udev: "./configure --with-udev-hotplug=/lib --sysconfdir=/etc"
   6. "make"
   7. "su"
   8. "make dev"
   9. "make install"
   10. "add /usr/local/lib to /etc/ld.so.conf"
3. Testing:
   • In comedilib there's a directory which is called "demo". Please try out:
     • ./cmd (reads 1 sec of data)
     • ./insn (reads 10 values from input 0)
     • ./outp -s 1 2000 (outputs 1000 to the output 0)
     • ./ao_waveform (10 Hz sine wave at output 0)
4. Testing modules:
   • Before doing a 'make install' just try to load it and test it. You can use the 'insmod' command to load themodules for testing, e.g.:
     • cd /path/to/comedi/comedi/drivers
     • insmod comedi.ko
     • insmod 8255.ko
     • insmod adv_pci_dio.ko
     Use 'rmmod' to unload the module after testing, e.g. 'rmmod adv_pci_dio'.
