I compiled the tarball on ubuntu 12.04. Two little issues: First, it needs package libudev-dev in addition to libudev. Took a little while to realize that sometimes "dev" means /dev and sometimes it means "development." Second issue is with the Makefile in src/data: Resolution into udevadm doesn't quite work, and I kept getting "sudo: DEVADM: command not found". Took a while to understand. I'm lazy, so I just forced install-data-hook to use $(UDEVADM) rather than $(UDEVADM_COMMAND). In the app, "wm100 -h" doesn't work because the getopt_long() call is missing "h" in the 3rd arg. It should be: getopt_long (argc, argv, "hgcis::d:tvle:", long_options,&option_index)) != -1) The device sample rate is wrong. I have it set for 5sec, but the app is fixed at 2s. The windows wm100 application lets you change the sample rate. Other than those little things, all seems to work OK.
