[solved] Need help debugging logkeys

SanskritFritz · 2011-11-02 12:23:26

It looks like there is an archlinux specific problem with logkeys:
http://code.google.com/p/logkeys/issues/detail?id=60
I also am hit by this, and would like to ask for your help guys. Any idea what could cause this?

In a nutshell:

strace -f logkeys -s

shows that the logfile could not be written for some reason:

[pid 10516] write(1, "Logging started ...\n\n2011-11-02 "..., 48) = -1 EBADF (Bad file descriptor)

The comments all have in common that they use archlinux, hence I dared to post here.

I have the exact same problem here, getting bad file descriptor errors. It simply doesn't work. When pressing the 'a' for instance:

write(1, "a", 1)                        = -1 EBADF (Bad file descriptor)

As I understand It tries to write 1 character from the string "a" to the file descriptor 1. What exactly is the fd number one? Also noticed that in my case the read calls, reads the key inputs from fd 0 - assuming this corresponds to /dev/input/event0? Should I 1+ this on googlecode?

Hmm, this sounds like the STDOUT?

That might be. You can change this on the command line, see the man.

I think you should.

Correct. From man stdin: ... the streams stdin, stdout, and stderr are (associated with) 0, 1, and 2, respectively ... Just for clarification. Left my comment on google code.

For the record:
http://www.linux-archive.org/general-di … gkeys.html
The logkeys-svn package already contains the patch by upstream, and I applied the patch in the logkeys package for the time being.
