[yocto] how to execute bitbake menuconfig from ssh server

[yahia farghaly]

Hi,

I am working with yocto from a remote server using ssh. i want to
execute *bitbake
-c menuconfig virtual/kernel* . It fails to open since it tries to open
another shell.
how can i redirect output of menuconfig to my current ssh session ?

Hello

You can use screen.
If your host is ubuntu,you can get via apt as follows.

sudo apt install screen.

If necessary , you can set auto or screen to OE_TERMINAL environment.

Tmux [0] also works well for this, and I've never tried it with Screen (a
similar utility) so here's instructions using Tmux:

You need to install Tmux on the server you are using SSH to connect to,
then as soon as you SSH into the server run `$ tmux`. Then when you run `$
bitbake -c menuconfig ...` it will automatically open a second pane on the
bottom half of your screen where you can edit your kernel config. That
pane will close automatically when you exit the menuconfig application.

I hope that helps!
Aaron

I mostly remote into my server via SSH too. And I use the screen method
to run menuconfig and devshell and so forth. Works well.

As Yusuke says you can install screen on the server (if it is Ubuntu or
similar) if you need to with

$ sudo apt install screen

You might need to tell the bitbake tooling to use the screen utility
which you can do with something like

$ export  OE_TERMINAL=screen

I see there are some notes here

https://books.google.co.uk/books?id=yNi6BwAAQBAJ&pg=PA35&lpg=PA35&dq=yocto+OE_TERMINAL+screen&source=bl&ots=HYab5gQgCg&sig=-qLFfrNLtglXCKwagcbU2Uqg1WM&hl=en&sa=X&ved=0ahUKEwie667diqLWAhUkLcAKHfXDBZwQ6AEIQzAD#v=onepage&q=yocto%20OE_TERMINAL%20screen&f=false

...

I hadn't heard of tmux. Thanks Aaron - I will have a look into that...

...

Sometimes I need a graphical environment. For example when I want to run
up a Yocto Poky build for testing on a QEmu emulated machine easily.

For this I have VNC Server installed on the build box. I then run this
up and it creates a new desktop. Your default desktop is usually :0 and
in my case VNC then creates a :1 desktop

This usually ends up on build box local port 5901 as I recall (if not it
will be a similar number, you can check with netstat -anp)

You can then port forward the VNC TCP port 5901 over SSH and use a VNC
client on your client local port.

I often use Windows as a client so use Putty for the port forwarding and
TightVNC for the VNC client.

This could well sound quite fiddly but it's fine when you get it setup.

There are some notes here which might be useful

Nice Aaron, it worked as charm. Thank you !

Alex, i will try your way. but you can test qemu without vnc by
specifying *serial
nographic* of runqemu options

Yes. I'm generally have a need for graphical output for testing though :)

You can actually use the in-built qemu VNC server if you change the
options too...

For technical knowledge, why is it failing from the first place ?

from my observation, It seems to try to execute gnome-terminal by default,
so i installed it but it failed to open it. even when i tried with ssh -X ,
it opened gnome-terminal but print the same failure messages within it.
