[maemo-developers] General Maemo/Scratchbox/N800 help

[From: David Hazel]

Hi Frank,

Thanks for your answers. There's one that I'll need further help with,
however:

>I put the executable on the memory card, copy it to my home directory
>and run it. You'll need xterm on the 800 to do this.

Question 1: How do I get a version of xterm that will run on the N800?
Question 2: How do I install it to the N800?

I'll need fairly detailed instructions for each of the above, I'm afraid. I
did try to download what purported to be an Openssh client for the N800
yesterday, but all I got was a file called openssh-client.install, and no
clues as to what I was supposed to do with it.

I did once try putting my executable onto a memory card. However, I wasn't
able to run it even though I thought I had built it for the right target
(which is ARMEL, I assume?) and the version I built for X86 runs (almost)
fine on Scratchbox. (I say "almost" because the emulator doesn't appear to
be all that close an emulation of the target environment. It apparently
can't simulate the presence of memory cards or give me an internet
connection, both of which are central to what my application is trying to
do.)

Hi David,

I started working with the 770 a month or so ago so I don't have all
the answers but I'll give a few below a shot.

I didn't find the need to do this. Using scratchbox to develop was
enough. So far, only one problem has appeared on the tablet and not in
scratchbox.

I didn't find a need for these at all, I still don't have root on my 770.

I put the executable on the memory card, copy it to my home directory
and run it. You'll need xterm on the 800 to do this.

Here is my cheat sheet.

How to build:
./autogen.sh
automake
./configure
dpkg-buildpackage -rfakeroot -b

How to run
outside of scratchbox:
/scratchbox/start-xephyr.sh &

To start scratchbox:
/scratchbox/login

inside of scratchbox:
export DISPLAY=:2
af-sb-init.sh start
run-standalone.sh <application>

To change targets:
sb-menu

To install in emulator:
fakeroot dpkg -i maemo-soundbridge_0.1_i386.deb

Hope this helps.

Frank
