thank you fossfreedom. i did it, this is the result:

chown: invalid option -- 'r' Try chown --help' for more information. user1@ubuntu:~/src/wl/sys$ sudo chown -r user1:user1 * chown: invalid option -- 'r' Trychown --help' for more information.

(my ubuntu ver. is natty 11.04)

i tried chown --help , i found that -R is correct, and i learnd -f suffix. BUT make command does not work and result is same as thah i wrote.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

The permission denied message could be that at some point you ran make as root


sudo make


cd /home/user1/src/wl/sys


sudo chown -R user1:user1 *

The MUTEX error could be due to the initial permissions issue. Fix that first, recompile and see if the error still occurs.

IMPORTANT: the pwd command should display "/home/user1/src/wl/sys" i.e. that you have correctly navigated to that subfolder

the chown -r command will change all permissions in that folder and all sub folders to the user1 user (and his group)
