Beginner - building the Kernel

[zaquadnik]

Hi.
I try to build Linux kernel as desribed in the iMC233-OLinuxIno manual. When I try to run menuconfig as desribed:

Code Select Expand

~/fsl-community-bsp$:. ./setup-environment build
~/fsl-community-bsp/build$:bitbake linux-imx -c menuconfig

And i receive following error:

Code Select Expand

I am using Ubuntu 10.04 with kernel 2.6.32-43-generic. What can be wrong? Anyone had maybe similar experiences ?

The error "Cannot open display" and failure to execute "gnome-terminal" indicate that you are either not running in an X environment, or have something else stopping another terminal session being started.

So, are you logged into the Ubuntu machine via a graphical session ?

Yes, I have X session started, but for different user. Than I open terminal and switch user with su command. Maybe this is an issue.

[Kean]

OK, sounds like permissions then.
I don't use X much, but from memory I think you might need to use "xhost" command.

Yup, the issue was the permissions. Strange, normally menuconfig is launched in the same terminal window, without launching another window.
