Sakura uses
vte which is easy to compile for the DR (I used version 0.17.4) with Anjuta. It even has a small example application that uses the terminal widget of the vte-library.
So far for the good news ... I can start it (the little app of vte and sakura) on the emulator, but I do not see anything but a white block (black for sakura) and the keyboard. Entering 'exit' stops the program, entering 'ls >somefile' creates the file, so the terminal-part seems to work, but getting output on the screen is the challenge...
Any help is welcome
