Hi Adriano,

Interesting. I will look into doing that soon as I get time.

Cheers!

Donal,
After installing armel/lenny on my tpc-7390 and making QT with eabi crosstool i noticed my application became much faster.

Maybe you can try on etch whit eabi "-static" (if you didn't). For me the program's got too large.

However, I recommend to change because lots of libraries can't handle oabi endianess (i think tiff on qt, for example).

So, if you (or someone else) want to try:

- make a new sd with ts-ftp sd-image;
- install armel-lenny also from ftp;
- change /etc/modules to install the modules you want to use;
- dowload armv4t-crosstool-linux-gnueabi from Martin's page;
- compile QT and your application with this crosstool...

Regards

Adriano
