assembler error in qt

[guruvadhiraj]

Hi,
iam using qtembeddd4.4.3. Iam trying to build qt for ARM processor . During the build iam getting an Assembler error as `swpb %cl,%al,[%esi] in qfutureinterface.cpp. what is the condition which results in this error?. qmake that is generated clears tells it is for ARM version. i gave file qmake command and made sure it corresponds to ARM version

this is my config command
./configure -embedded arm -xplatform qws/linux-arm-g++ -little-endian -no-webkit -no-mmx -no-sse -no-3dnow -no-sse2 -armfpa -no-cups -no-nis -qt-gif -qt-libpng -qt-libjpeg -qt-libmng -qt-libtiff -qt-zlib -no-sql-ibase -no-sql-mysql -no-sql-odbc -no-sql-psql -no-sql-sqlite3 -no-sql-sqlite2 -no-dbus -no-freetype -no-glib

I tried without -platform linux-g++-32 command as well but no luck.

This is the error

Is swpb a valid instruction for ARM? Is there a chance you assembler doesn't support it even though it's valid?

It looks like you have the same Problem like me. So what’s the solution? Did you found one?

[aleks_ivanov]

Hello ,

I have the same problem building Qt-Extended-4.4.3 for ARM with the same qfutureinterface.cpp file.

I dug deeper to find the reason and here is what I found:
- I am compiling with the option -mthumb which instructs the assembler to use the Thumb set of ARM instructions.
- The instructions SWP and SWPB are available in all ARM architectures instruction sets.
- The instructions SWP and SWPB are NOT available in Thumb mode.

I removed the -mthumb option from my configuration and the problem was solved.
I still do not know why the qfutureinterface.cpp is needing these instructions - I believe it is something related to critical sections (QMutexLocker).

Regards,
Aleks

Hi,

I am using AM3517 EVM and omap3_qt46_config.patch so that I can run the demos on EVM kit. I have attached the cofigure_omap3 file below for reference.

./configure_omap3
gmake

but it gives me similar errors. I don't see any option like -mthumb.

Please, tell me what I should do to resolve this error.

regards,

Hi,

the "-mthumb option" is actually a compiler flag. You have to edit the configuration of your compiler, not the qt configuration.

[QT-embedded]

ok.

I am using the CodeSourcery toolchain of ARM GNU/Linux 2009q1

do you know in which file do I need to make changes? I do not know at present.

[QT-embedded]

ok. thanks for the quick reply.

Sorry for updating old thread, but this might be useful for future readers (this thread comes first on Google).

I got the same error, not because of a -mthumb, but because it was compiling with g++ (x86) instead for the cross-compiler.

I tried "configure -embedded arm-gnueabi ..."
I tried "configure -embedded arm -xplatform qws/linux-arm-gnueabi-g++ ..."
I tried "configure -embedded -xplatform qws/linux-arm-gnueabi-g++ ..."
Nothing works, it always end-up mixing up the g++ and arm-linux-gnueabi-g++ stuff.

The internals of the configure script attempts to be smart about guessing the platforms (QWS yes,no,maybe stuff), but even "./configure -embedded -help" is not clear about the "official" parameters for cross-compiling.

I can't confirm that older posts had the same issue, because none of them included the full compiler command line leading to the error messages.

[zxzxy1988]

hi
I'm sorry for posting an old thread, but I've encountered the same problem when compiling the qwt.
but maybe my problem is easier: the same program can go well in x86-arch qmake, but cannot go with the arm-arch qmake.
so I clean all the project, and rebuild it.
It works!
