I patched and flashed the kernel, i could see the squashfs-module was built but im not positive that everything is alright with it. modprobe doesnt work on the 770.
I tried to mount a squashfs-image with "mount -t squashfs -o loop file.image /dir" but i got a "no such device error".
I got the same error before i patched the kernel.

Im out of ideas for the moment, maybe someone can inspire me?

I really don't like kernel patching: perhaps try squashfs as a module?

Offline applications (except offline navigation applications!) are kind of a low priority for me, as I have a BT cellphone and unlimited data plan.

That said, I will throw some cycles at it, as the heavy lifting should already be done

http://code.plkr.org/ep/ seems Very interesting, by the by.

Hmm, i think i am a little confused about this kernel-config thing.
I looked at the default kernel-config and could not find squashfs and assumed its not in there. So i patched the kernel and after some more wondering i just added CONFIG_SQUASHFS=m into the config myself.

And yes, the plucker thing looks great and i would certainly pay for it but it has not been updated since may, i hope its not abandoned.

it works now.
-o loop is not supported by the mount-command on the 770 but somebody from the mailinglist made a binary of losetup which lets you work around that.

Now with squashfs i could shrink the german wikipedia (no pictures, discussions, user-pages...) to 1.75GB and can barely fit that on my 2GB card but hopefully i will find more stuff to delete so that i can fit a few other things onto the card as well.

I will state, for the record, I still hate webapps.

For those interested, please take a look at:
http://users.wpi.edu/~chaos/wiki.squashfs (63MB)

Mount this (or unsquashfs it, but that will more or less quadruple it!) and you'll have a small subset of articles (from Wikipedia-on-CD-2006) and a working JavaScript-based search engine. Runs quite sexily on my N800 in unsquashed form, haven't -quite- gotten squashfs working yet.

My next project will be a http://wikifilter.sourceforge.net/ distribution that will target the 2GB cards and include a more powerful search feature, etc.

Enjoy!

These guys have an offline Wikipedia for CDs:

If I understood correctly, they have also experimented with Wikipedia for Nokia 770.

(there's atleast one other thread about this on this forum btw)
