Hi Doron, my guess is that you updated the log4cpp header files, but your ld is still linking to an older version of log4cpp, or vice versa. Since (as far as I know), gr-osmosdr doesn't use log4cpp itself at all, this would, for example, happen, if you have a GNU Radio installed that was built agains an older version of log4cpp, and then you've updated log4cpp, and now are trying to build software that links agains GNU Radio.
