bitbake -c menuconfig linux-fslc in a tmux window

Hello list,

if I start the following command in a tmux window it doesn't work.

bitbake -c menuconfig linux-fslc

if I start this command in a extra gnome-terminal a new gnome-terminal pops-up and I can configure my kernel related stuff.

in the poky /os-poky/meta/lib/oe/terminal.py there is some code that indicate that it could be possible that a new tmux-pane should open here.

Some clue why bitbake does not open an extra tmux-pane for me?

I'am using yocto jethro 2.0.2.

Best Regards,

Oliver
