Maemo 3.0 on Fedora Core 6 (N800 development environment)
Maemo 3.0 (Bora), and Scratchbox APOPHIS installs just fine on Fedora Core 6. Its important to probably follow the install documentation, and do just a few other things.
First of, it starts with the installation. If you’re on an x86_64 platform, it is suggested that you have some kind of chroot environment setup. In Debian land, you might find reading Maemo 2.0 on AMD64 handy, however in Fedora-land, there’s a great utility called setarch.
SELinux should be disabled before installation. As root, type echo 0 > /selinux/enforce. Then proceed to install via:
setarch i386sudo ./maemo-scratchbox-install_3.0.sh -s /opt/scratchbox -u username
The above installs it to the path /opt/scratchbox, and adds username to the sbox group. Now, while in your i386 “chroot”, run, sudo /opt/scratchbox/sbin/sbox_ctl start, and try running /opt/scratchbox/login. You should be greeted with a prompt like: [sbox-SDK_X86: ~]>.
Outside of Scratchbox (I suggest you exit it), run bash maemo-sdk-install_3.0.sh -s /opt/scratchbox (the -s specifies the path, if you installed it in /scratchbox, its not necessary). Continue following on the instructions in the install documentation.
Pull down Xephyr via YUM – its xorg-x11-server-Xephyr. Remember that all this won’t work unless you’re in the sbox group, so if things seem to be broken, run id and see if you can see that you’re a member of the sbox group.
At startup, just run setarch i386, then don’t forget to start scratchbox via sudo /opt/scratchbox/sbin/sbox_ctl start. Fire up Xephyr, via Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac (this should be done outside your setarch-ed environment), and then login to scratchbox, export the display to :2, and run af-sb-init.sh start. You should have the Maemo environment running now.
Update: Russell Coker dropped me a line, and yes, while I don’t simply encourage the turning off, of SELinux, this was not implied by me. There’s a test in maemo-scracthbox-install_3.0.sh that checks on this (lines 420-427), and it recommends that it should be dropped to permissive mode. You can also obviously use the setenforce tool. Also, if you’re looking for a guide to Xephyr, he’s got a resource that’s pretty good.
[…] just learnt that that on i386, vdso will need to be disabled if you’re setting up Maemo 3.0 on Fedora Core 6. And I also learnt that on x86_64, there is no vdso. Props to #fedora-devel, and […]
It’s been working well for me even without the setarch. Scratchbox 1.0 is turning out much nicer than the older version!
Cool, thanks for the information. Odd that it mentions its x86 only, it actually works out of the setarch. Did you set it up in full x86_64?
Yes; I just set it up as if I’m running on i386. There are some issues — I have to re-run the run-me-first.sh script at every boot-up, but apart from that things work fine.
Do you have a problem logging /out/ of Scratchbox? I get the following (on Rawhide), with and without setarch.
/opt/scratchbox/login: line 316: kill: (-17208) – No such process
Hi Colin,
I read your blog with interest, i wonder if you are aware of like minded maemo developers in the australia, would it be possible for you to get in touch with me?
Kind regards

Hi,
Thanks for your useful guide. It helped me a lot. Just a small problem: I don’t know how to set qemu for scratchbox. sb-menu shows only target and something related. sb-conf ls -t shows me a lot of qemu but I don’t know how to specify a right qemu: sb-conf st -t ???
Could you help me out? Thanks very much!
OK. I got it. Thanks.
