how to build qt applications for arm specific target boards

[sancti]

Hi all,

I have installed QT-4.6.0 linux version in my pc. Qt target version is running successfully on the target boards. Now I am trying to build my own arm specific applications for the target boards. But I am not able to do the cross compile versions for the applications. Can anybody please help me how can I do the cross compile for the application to run successfully on the target boards.

Thanks in advance

First you need to set-up root file system,cross compiled libraries, and tool chain(ex:arm-g++) of your target on your developing environment(i.e on your desktop).

hi,

Thanks for the reply. I have already done the RFS cross compilation tool for arm specific target version. This arm specific version is successfully running on the target board. Now I am deploying small application on the target board. The application runs on the desktop pc. But I am finding difficult when I try to cross compile the application for the arm specific version. Can you please guide me regarding this.

Well it depends what IDE you are using, i'll tell you how to setup the Qt Creator.

1. Define the tool chain to cross compile the code, i.e add the cross compiler. Do that in Tool -> options -> Tool Chains.
2. Now you have to add cross compiled Qt in the Tools->options->Qt4, it should be auto detected if the path of qmake is in the PATH variable or manualy do that.
3. Now when you create and application, i.e. new project in QT creator in the target setup dialog ->create build configuration-> You can setup the builds either for embedded only by selecting manual or select to create build for each Qt version configured.
4. While building the project switch from desktop build to embedded build from projects->Edit build configuration

Note: You may have to explicitly specify your cross compiler in the projects settings by providing additional arguments eg -spec linux-arm-g++

Hope this helps
