problems with making cross compiler

[nataly]

hello!

i'm trying to make a cross compiler with the instructions in this link:


http://labs.trolltech.com/blogs/2009/09/10/cross-compiling-qtx11/

i built angsrom and created scratchbox2

after the topic "Cross compiling Qt/X11" in the link:

i changed the qmake.conf like they say.
than, the instructions say:

you can export PKG_CONFIG_PATH to point to your targets

pkg-config (.pc) files, which are normally in a pkg-config directory under

the targets lib directory:
$targetPathOnHost/usr/lib/pkgconfig. Please note this path must be fully

qualified relative to the host)

i dont understand how do i do this.
thanks.

To export a variable, you have to use a proper shell command. For bash it is called "export":
export SOMEVAR=somevalue

thank you!

i succeeded making the cross compiler.
(l used this link http://labs.trolltech.com/blogs/2009/09/10/cross-compiling-qtx11/)
now i have other problem.

I tried to use the cross compiler. i can build a project to intel,
but when i tried to build to arm , it didn't recognize the libs of qt.
i changed the path in the qt creator - in the build steps ---> additional arguments by :

-spec (and i wrote the path to the new qmake.conf which i did)
and this is what i got in the compile output:

Running build steps for project hello...
Configuration unchanged, skipping QMake step.

Error while building project hello

than i tried in the command line to ran this:
./configure -arch arm -xplatform /usr/share/qt4/mkspecs/linux-g++ -force-pkg-config
make

and this is what i got:

../../include/QtCore/qatomic_x86_64.h:133: error: impossible constraint in 'asm'
make[1]: *** [.obj/release-shared/qabstractanimation.o] Error 1
make[1]: Leaving directory `/home/gt/qtsdk-2009.05/qt/src/corelib'
make: *** [sub-corelib-make_default-ordered] Error 2

how can i make this to recognize qt's libs??


thanks!
