I'd like to make some development for N900.

I tried to install scratchbox the graphical way :
sudo ./maemo-sdk-install-wizard_5.0.py

It works until 30%, then I get an error :

Setting up 'FREMANTLE_ARMEL' target.
Inconsistency detected by ld.so: rtld.c: 1192: dl_main: Assertion `(void *) ph->p_vaddr == _rtld_local._dl_sysinfo_dso' failed!

You dont have active target in scratchbox chroot.
Please create one by running "sb-menu" before continuing

So, I try to run sb-menu
Traceback (most recent call last):
File "/usr/bin/sb-menu", line 10, in <module>
os.execv(chroot,[chroot,p.basename(sys.argv[0])]+sys.argv[1:])
OSError: [Errno 13] Permission denied

sudo sb-menu
[sudo] password for delafond:
ERROR: Not allowed to run this as root!

All information will be received with pleaure ;-)

Add vdso32=0 to kernel parameters.

Don't, that's fixed in recent scratchbox versions ("Hathor"), or use http://depot.javispedro.com/nit/sbox/ . vdso32=0 might introduce performance problems in 32 bit apps.

I was under the impression that Scratchbox only works with a 32bit OS.

Is this still the case? Am I still unable to get scratchbox running on 64-bit Ubuntu?

I have scratchbox running on 64-bit Ubuntu (10.10) and have done installs on various 64bit ubuntu for the last 18 months all end up working just great.

The installation guide ( http://wiki.maemo.org/Documentation/...K_Installation ) may be slightly out of date as there a few minor differences:

needing to set vdso32=0 as a boot line instead of the quoted sysctl entry

If you have a problem with missing terminals in Scratchbox (switching targets etc) see:
