No, one file is the source file and the other file is the installed in
your gnuradio installation directory.

Try

   diff /usr/local/src/gnuradio/cmake/Modules/FindLog4cpp.cmake
/usr/local/lib/cmake/gnuradio/FindLog4cpp.cmake

That is, diff on the two files and make sure they're the same.

If they're different, I'm not sure which one it would be reading - my
guess would be the one
/usr/local/src/gnuradio/cmake/Modules/FindLog4cpp.cmake.

In any case, I'm not sure where you stand with this problem.

Did you receive a file from Marcus?
