Thread: Miredo Weirdness

  1. #1

    Default Miredo Weirdness

    I recently compiled and installed from source a program known as Miredo, for IPv6 connectivity. I successfully compiled and generated the necessary binaries to run the program. However, upon execution, they complained of an missing shared object file (libtun6.so).
    I spent hours googling a solution to no avail. I eventually gave up and shut down the system for the night. Upon booting up again the next day, the program executed without any problems.

    My question is this: Why would it require a reboot to work? No part of the compilation required messing with the kernel to my knowledge. I ask this because I'd like to understand my system a bit better.

    If you installed a new library during your travels, you need to run ldconfig
    to rescan the libraries. Rather like a giant 'hash table' which lets linux
    link libraries faster.

    After installing, or doing anything which changes/add/removes a library...

    (as root)
    ldconfig

    The libraries are rescanned on a boot... which is why it worked after the
    reboot.

    Similarly, if you install/add/change/remove kernel modules, you need to run
    'depmod -a' to update indexes... (as an example)

    Hope this helps
