Deploying program error with QT everywhere

SGaist

Not Qt Creator, it's just the IDE and you don't need to cross-compile it unless you plan to run in on your target.

How did you install your cross-compiler ?

zdenekrejci

Iam now a litle bit confused.. you say not the qt creator but IDE... isnt QT equals IDE???

SGaist

No, Qt Creator is the name of the cross-platform IDE the Qt Company is developing for developers. Qt itself is a pretty large framework.

@SGaist Hi, still trying to make it work whenever I have a little bit time. Iam trying different versions of qt everywhere. Also would have a question, what is the differene between qt-everywhere and qt-embedded? is it only about different name or there is something else?

SGaist

If you are referring to the package name, yes. Qt Embedded was meant for devices without X server providing QWS. Qt everywhere is for all supported devices.

@SGaist Next test>
I have no package none-gnueabi so I deleted the "none" from
mkspecs/qws/linux-arm-gnueabi-g++/qmake.conf

the problem i thing could be still that in qt creator i can see the name of the
compiler is
arm-linux-gnueabi-g++ in my host system
but the one that I can select in qt-everywhere ...mkspecs/qws/ is
linux-arm-gnueabi-g++

anyway Iam going to try to configure and make

./configure -embedded arm -prefix /usr/local/qt4-7.3 -little-endian -no-qt3support -no-cups -no-largefile -optimized-qmake -no-openssl -nomake tools -nomake examples -no-webkit -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++

make
make install

compiled and installed
QT creator showing on run
bash: /home/olimex/untitled8: No such file or directory
Application finished with exit code 127.

and if I try create non qt in qt creator like standard console application everything is ok i can build and deploy on target.

back to qt application, if I try ldd on executable on target I get nothing...? Somehow is the qt-everywhere not working... I thign... Any ideas?

@SGaist There is also one thing I found in settings for the compiler there is parametr arm-linux-generic-32-bit itsnt this the problem? should not be there something like i386 or different? The board onlinuxino with armv7 is not 32bit..so?

SGaist

That's the cross-compiler, it indicates the target for which it will compile your application.

zdenekrejci

@SGaist I know its indicating the target but my target is not 32bit as far as I know.
armv7 is not 32 or 64. Thats what I have read in different forum. So what I ask is
"should not be there something like i386 or different?" in the compiler settings?

And when I try to compile qt-everywhere version 4.7.3 with compiler arm-linux-gnueabi-cpp and try to run it on target it gives me output

bash: /home/olimex/untitled11: No such file or directory
Application finished with exit code 127.

SGaist

What does file /home/olimex/untitled11 tell you ?

i386 is for Intel/AMD processor. ARM is also available in 32 and 64bit architecture.

What is your target board exactly ?

zdenekrejci

@SGaist
What you mean by "What does file /home/olimex/untitled11 tell you ?"
the ouptut when I call it is bash: /home/olimex/untitled11: No such file or directory
Application finished with exit code 127.

Then it means that the file wasn't copied over to the target.
