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.

Re: Everybody please fix bug in your scratchbox installation! [In reply to]

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.

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.

Re: Everybody please fix bug in your scratchbox installation! [In reply to]

thumb in DEB_BUILD_OPTIONS does not enable anything, but there are packages, who check for that in their debian/rules file and pass -mthumb to compiler if found(modest, HAM and osso-gnome-vfs for example).

-mthumb passed to gcc enables thumb2 instruction set, as the other options tell the compiler that CPU is arm7.
