QT Creator cross compiling

TheHost

Hello I am using A13 olinuxino board and QT Creator. I try to cross compile my QT Creator files but I dont know how. I try to look from the internet but there are too many not understandable information on the internet. I'm stuck right now. Can someone help me about this. I am new to cross compiling world.

Hi and welcome to devnet,

Are you asking how to cross-compile "from" QtCreator or how to cross-compile QtCreator ?

TheHost

Thank you, I'm asking how to cross-compile QTCreator

SGaist

So you want to run QtCreator on the board to develop your Qt application ?

TheHost

Actually I want to create and compile Qt application on my computer and then run it on board. I am sorry If my English is not understandable

Hi i have used QtCreator for developing application. Now that application is running on my host machine. Now i want to use QtCreator to cross compile the developed application. Is there any procedure to cross compile in QtCreator.

SGaist

First thing to do is cross-compile Qt, then add that new build to the known Qt Versions of Qt Creator, make a kit with it and use it

vsrk

Cross compiling the Qt is through command prompt only?

Assume that i have cross compiled Qt through terminal. My next question is how to add that new build to QtCreator?

SGaist

Yes it is.

Qt Creator -> Preferences -> Build & Run -> Qt Versions

Hi SGalst,

I have cross compiled my Qt open source 4.8.5 and build the Qmake with ./configure options......

Now i want to give this Qmake path to the Qtcreator......through Tools->options->Qt4 and add....

now when i add its showing some danger symbol and telling Qmake link broken.....

i am using QtCreator 2.3.2......

Initially i thought may be using old QtCreator.......then i added this Qmake which i made with Qt4.8.5 in the Qt creator based on the Qt 5.2 even then i am getting error saying that No compiler can compile this Qmake..

Please help me...

SGaist

First thing to do is update your Qt Creator to at least 3.0.0 otherwise your won't be able to use Qt 5.2

Hi SGalst,

i have changed all the versions following versions am using.

I am using Qt source libraries from 4.8.4

and Qt creator am using is 2.7.2 which is based on Qt4.8.4....i think there wont be any issue with this right?

I just want to update further:

I successfully configured the libraries with the following configurations.

export PATH=$PATH:/home/anoop/Desktop/arm-2011.03/bin
arm-2011.03/bin: These binaries downloaded from CodeSourcery (Mentor Graphics) site.

./configure -qpa -arch arm -xplatform /home/anoop/Desktop/qt-everywhere-opensource-src-4.8.4/mkspecs/qws/linux-arm-gnueabi-g++ -no-largefile -no-accessibility -verbose -little-endian -no-webkit -prefix /home/anoop/Desktop/ARMBuildQt -no-qt3support

afterwards i did make and make install.

Now my build Qt libraries are there in ARMBuildQt folder.

I have opened QtCreator 2.7.2 and given Qmake path for Manual Qtversion

Now it says there is no compiler to compile, Now i have added compiler as arm-linux-gnueabi-g++

after all this it saying configure the tool kit....i dont know what to fill in that toolkit option...

Please help me i am really stuck at this point.
