  • Hi, using the defaulted Debian package, I installed OpenCV and get a complaint about a problematic CPU frequency. From the strace I could see that it is indeed /proc/cpuinfo that is consulted. And indeed, it reads 0.000 for the cpu MHz:

    moeller@colinux:~/src$ cat /proc/cpuinfo

    moeller@colinux:~/src$ uname -a
    Linux colinux 2.6.12-co-0.7.1 #1 Sun Dec 10 13:28:43 CET 2006 i686 GNU/Linux

    What could I do? At least google did not find this reported anywhere.

    Cheers,
