/dev/log/main not found

Question

I'm trying to develop an Android application but when I try to connect to logcat I get the following error:

Unable to open log device '/dev/log/main': No such file or directory

I already installed a new SDK, rebooted my phone... nothing seems to solve the problem. Anyone has any solution?

Samsung Galaxy S (Darky's v9.1)

Apple OSX

ADB 1.0.26

By connecting to logcat you mean issuing a `add logcat` command? — Octavian A. Damiean, Feb 01 '11 at 21:12
What does the output of `adb shell ls -l /dev/log` look like? — Octavian A. Damiean, Feb 01 '11 at 21:20
/dev/log: No such file or directory... I tried creating the files using the terminal, but after reboot they were gone... — ferdyh, Feb 01 '11 at 21:23
Those are special system files which can't just be created. Very weird tho. So the entire log directory is missing? — Octavian A. Damiean, Feb 01 '11 at 21:39
Indeed... I read something about it has to be enabled in the kernel, however i talked to Darky and he said its no kernel problem... (His words, not mine...) — ferdyh, Feb 01 '11 at 21:40
It seems this is related to kernel of the rom. Is there any solution to this `Unable to open log device '/dev/log/main` error with Franco kernel? — NoBugs, Mar 22 '13 at 01:36

I had used the Speedmod kernel; This has default Logging disabled. Re-enabled it in the TWEAKS menu.

Thanks for making me realise this Octavian Damiean

Btw, to access Speedmod kernel tweaks you have to restart in recovery mode. – arielsan Mar 22 '11 at 19:22

I found the following method on XDA:

adb shell
su
mount -o remount,rw /system
echo ANDROIDLOGGER >> /system/etc/tweaks.conf
mount -o remount,ro /system

and reboot.

For a rooted Galaxy Note 7000, run insmod /lib/modules/logger.ko in the shell (this is missing from the rootfs' init.rc), assuming you can boot up sufficiently far to access adb / some terminal like terminal-ide. The module mounts in /dev/log and provides the missing files.

This did it! But you have to type "insmod /system/lib/modules/logger.ko"! – c0dehunter Aug 14 '12 at 08:28
