need help in qt environment setup
Hello!
I am using yocto to build images and develop software for my freescale imx53 board.
I need some help setting up environment for QT based software development.
My software requires qt4 (embedded) support.
There is several ways to use toolchain.
First, I can use toolchain from build directory where I've compiled qt4-embedded recipe. There I create environment-setup script using command:
bitbake meta-ide-support
Second, I can build SDK for my image:
bitbake image-name -c populate_sdk
Third, I can use meta-toolchain-qt recipe to build QT containing SDK:
bitbake meta-toolchain-qte
The first two methods is most convenient for me, because I need some additional libraries that is not included in meta-toolchain-qte. The first method is better, because I develop software on the same host, where yocto is located, so I don't need separate SDK installation.
However, only the last method produces environment settings for QT placed in /opt/poky/1.6.1/sysroots/i686-pokysdk-linux/environment-setup.d folder.
Other two methods produce environment-setup scripts, but they don't create sysroots/i686-linux/environment-setup.d folder. So QT environment settings lacks from this installations.
The best way I would like to solve it, is to somehow make 'bitbake meta-ide-support' generate environment settings for QT in my build dir, so I can use my local (non-SDK) cross toolchain to build QT software. How can I achieve it?
It is ok for me to use SDK as well, however, I want it to be my image based SDK.
Thanks for any help.
Alexander.

and then use '${OE_QMAKE_QMAKE}' but not 'qmake' directly.

I used your suggestions and made it work for me with following differences:
- use of environment-setup.d folder (introduced with 457291f2ca084d1f43c0cca2175b448a22761887 and e7b9e1df19062cfbcd72c90295829424cae6fbed commits) instead of appending script.
- I created meta-ide-support.bbclass to avoid code duplication
Here is a draft patch attached of how I did it. I am ready to work on upstream-suitable patch for this feature, if someone wants to hint me how to do it properly.
