Re: [Discuss-gnuradio] log4cpp library not found

[address@hidden]

Regarding the Marcus cmake, I guessed that src would copy to lib, but
that didn't happen. (Easy to check by file dates.) I ended up copying
the new FindLog4cpp.cmake to both locations myself. I did a diff with
the -s option and they are the same. 

diff -s /usr/local/src/gnuradio/cmake/Modules/FindLog4cpp.cmake 
/usr/local/lib/cmake/gnuradio/FindLog4cpp.cmake
Files /usr/local/src/gnuradio/cmake/Modules/FindLog4cpp.cmake and 
/usr/local/lib/cmake/gnuradio/FindLog4cpp.cmake are identical


The problem is still there. I downloaded the log4cpp from the opensuse
repo, which of course would use the "normal" library (/usr/lib64)
rather than the local library, but that didn't work either.

So in summary, the problem is still there.
