Everybody please fix bug in your scratchbox installation!

Hello Maemo Community!

Now after long time I found a very very *big* problem in Nokia
Maemo SDK virtual image which can be downloaded from location:
http://tablets-dev.nokia.com/maemo-dev-env-downloads.php
file Maemo_Ubuntu_Lucid_Desktop_SDK_Virtual_Image_Final.7z

Problem is in scratchbox and may be in regular scratchbox
installation on desktop too (not only in virtual image)!

That Virtual image contains *thumb* string in scratchbox shell
variable DEB_BUILD_OPTIONS which cause that some applications
will be compiled with thumb instructions.

Thumb is unstable on default Maemo 5 for Nokia N900 and
applications which are compiled with thumb-2 will crash without
any reason.

Check if you have problematic scratchbox:

1. Login to scratchbox: run /scratchbox/login
2. print DEB_BUILD_OPTIONS in scratchbox: echo $DEB_BUILD_OPTIONS

If it does *not* show "thumb" your scratchbox is already fixed
and thumb is disabled. If it *show* thumb, disable it.

Instructions how to disable *thumb* string in scratchbox:

1. Login to scratchbox: run /scratchbox/login
2. Edit file /targets/FREMANTLE_ARMEL.environment
3. Remove "thumb" from that file
4. Save file and *logout* from scratchbox

Note that scratchbox is loading DEB_BUILD_OPTIONS variable at
startup, so you need to restart scratchbox to take effect. After
restarting please check again if thumb is really disabled.

I'm using scratchbox on Linux, and have thumb too. So it's a bug not only
in the virtual image. Or maybe it's "thumb-1".
But autobuilder is using scratchbox too, doesn't it? Are there problems
with some autobuilder built packages?

If you have thumb in your scratchbox FREMANTLE_ARMEL.environment
then bug is not only in virtual image...

Autobuilder using scratchbox too, but it set DEB_BUILD_OPTIONS
variable before bulding package. So deb packages builded by
autobuilder are not affected by this problem.

Yes, it's in FREMANTLE_ARMEL. In FREMANTLE_X86, $DEB_BUILD_FLAGS is blank.
It may be why there's a problem with libmeegotouch (segfaults and etc.), as
libmeegotouch is in non-free

Thumb is for arm processors, not for intel x86. If libmeegotouch
is compiled for fremantle with thumb then this is reason why it
segfaults.

Thanks, I have 2 instances of SDK VM and both had "thumb" enabled in
the options.

According to this:
http://forums.internettablettalk.com/showthread.php?t=84829 thumb != thumb2.
Will thumb in DEB_BUILD_OPTIONS enable thumb or thumb2? As I compiled
sqlite3 without changing the variable and works ok.
