Hi, i have the absolut identical file for Windows which works as
expected (logging), but not for linux:


There is just no logging - i started everything as root. Even when i
use the FileAppender with its file name property set to "somelog.log"
or "/root/somelog.log" it just saves nothing and i have no idea why.

I used updatedb && locate to find a file called like this but there
was nothing. Also lsof with a grep find nothing opened. So it is
really not logging.



Your config for the RollingFileAppender is missing the <file> element. The
manual contains a good example of all the necessary elements [1]. logback
should print a warning in the debug output for this.


It would be helpful if you provided additional details to reproduce the


 * What version of logback and slf4j are you using?

 * Which flavor (and version) of Linux are you running? 

 * Does the same problem occur when you try your logback config in a simple
HelloWorld app (outside of install4j)?


FYI, your logback config works (writes to a file) for me in Android.


It looks like Install4j supports a console [2], when running  the installer
with "-c". It might be worth seeing if logback's debug-output prints in that
