Running strace on Kobo

met67 · 07-26-2013, 08:42 AM

I've been asked more info on how I run strace on Kobo to gather infos on nickel (see here), so I'll open a new, dedicated, thread.

In order to run strace, you need to have telnet/ftp or ssh access to your kobo, you can find more info on this several threads here in MobileRead.

First step is to download strace.zip from this post and extract the strace executable from the archive.

Next put strace in your Kobo, e.g. in /root (you can use ftp for this).

Now you must flag the command as executable, by using this command from telnet:

Code:

chmod +x /root/strace

In order to use strace, you must launch a new executable or attach to a running process. Since nickel should be already running on your Kobo, you can find its pid with the 'ps' command:

Code:

ps | grep nickel

Suppose that the process id of nickel is 510, you can run strace on it with

Code:

/root/strace -p 510

If you are interested only in file operations, you can use the '-e' option of strace like this:

Code:

/root/strace -e trace=file -p 510

strace has a lot of other options, you can find them in its man page

Hope this helps.

Many Thanks. I've added this info to the post I'm maintaining on hacks and tools.

Does this work for FW 2.6+?

I've used this on 2.8.1, but I don't see any reason why it shouldn't work on earlier fw.

Thank you for the reply. I thought it might work only on FW prior to 2.6.
Edit: I see, this concerns only progs that work together with nickel or use qt libraries.
