How do I cross-compile a QT application for a Freescale Hummingboard(imx6(arm))?
There are some guides around, but I've not been able to complete one with success.
The following (and more) guides give me a compile error on ./configure

When I run the ./configure command (With recommended commands, I've tried this with a lot of possibilities for commands but got none working). I got a compile error for all the external libraries QT uses (zlib, libjpeg, libpng, etc.). So it's a dead end from there.
I've tried a lot more stuff, I don't even remember all the stuff I've tried, but I got nothing working.
I'm trying to use mini-distribution for the Hummingboard. It's a system without window manager that is able to run QT applications (QT5). The build tool I'm trying to use is gcc-linaro-arm-linux-gnueabi, I'm using QT Creator. I've got QT working on the Hummingboard, I just can't compile anything for it.
I managed building an application for the IMX6 finally. Here is how I did it for other's. It's not an optimal solution but it is an solution.
I use Buildgear to build mini-distirbution as OS (Google it, not enough links with my reputation). I append my own application to this mini-distribution to also build it. This is done by placing creating a folder in the buildfiles/cross/cross-hummingboard folder and adding a buildfile (mine look like this http://pastebin.com/bZkJUiry). In this folder I also place a .tar of the project files (including the .pro). To get it to build I add "qt-gui" as a dependency to the fs (buildfiles/cross/cross-hummingboard/fs) by adding it to the list of depends.
I then run buildgear build fs, which will create an (Tarred) image including my (working) qt-application! I then extract the ./qt-gui executable and ssh it to the Hummingboard.
Of course this is all a bit cumbersome so I made a script that automates this all: http://pastebin.com/jFM6rZyY
It copies and Tars sources, compiles it together with the fs, extracts the executable, ssh's the file to the hummingboard and runs it. Takes about 3 minutes building but it works which is what counts for me at this point.
