Build errors in cross compile Qt for embedded linux

rahul3349

Yes, I've all deps/libs in my sysroot, I'm able to cross compile Qt by resolving build errors. Problem is I need to create patches of fixing build issues and maintain it per Qt version.
I'm expecting, Qt should be built w/o any build errors.

rahul3349

I've to create patch like this in order to fix build issues in qtbase

SGaist

It should yes, that's why I'm thinking there something funky going one. Did you get the sources from git ?

rahul3349

Yes, I'm using source from git. Am I doing something wrong here?

SGaist

No no, it was just to know where you got the sources from.

What distribution do you have on your sysroot ?

But what Linux distribution are you using for your target sysroot ?

rahul3349

Ubuntu 15.04

SGaist

Ubuntu on the target and as sysroot ?

rahul3349

Ubuntu 15.04 is on target. I created sysroot by downloading arm 64 bit deb packages to resolve all Qt dependencies on host.

SGaist

One possibility is to add the QTextStream include where that error appears.

As for the X11 related errors, try moving the X11 includes after the Qt includes.

rahul3349

My intention behind starting this discussion is to avoid resolving build errors when I sync up or switch to new Qt version at my side. As I mentioned I've already resolved build errors and created patches for some Qt versions. But if those errors are fixed there itself as these are genuine build errors then developer do not have to resolve these errors for linux embedded platforms.

SGaist

Did you submit your patches for inclusion in Qt ?
