assembler error in qt

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?

Hey everybody,

here is my problem:

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

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 :confused: - 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.

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.

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.

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!
