Linux: I cannot change permission atributes by chmod command w/ a root user

[andre_luis]

Hi guys,



I´m working on an Ubuntu based embedded system ( PCduino ), and I´m having problems to execute compilation on a GUI application ( QTcreator ), because it is presented a message box : "Error - Cannot create file XXXXX : Permission denied" during the MAKE process.

I must confess that I´m not an expert on Linux, and taking a look on the web, I found several variations of chmod command, which could change permission of the folder ( and its sub-folders ) and despite try a lot, no one retrieve desired result, holding original atributes.

In order to know if logged user was able to perform this operation, I typed whoami and as expected, gave root.

I presume that Ubuntu is not running as a super user - Is it possible ?

Are you sure the partition to which the compilation process is attempting to write is mounted as read/write and not read only?

Hi Big,


I solved the problem faster than I supposed :
The solution I searched on everywhere at the Desktop panel and I found on Ubuntu environment, this way :

FILE MANAGER (select desired folder) >> TOOLS|MENU >> OPEN_WITH_ROOT_USER|SUB_MENU (now can change permissions w/o errors)

Works as a charm !
