How to configure QtCreator with Yocto sysroots

Mark81

I successfully built a Yocto project that contains the meta-qt5 layer.
At the end, I found:

tmp-glibc/sysroots-components/x86_64/qtbase-native/usr/bin/qmake
tmp-glibc/sysroots-components/x86_64/qtbase-native/usr/lib/libQt5Core.so.5.11
tmp-glibc/sysroots-components/cortexa7t2hf-neon-vfpv4/qtbase/usr/lib/libQt5Core.so.5.11

Of course along the other libraries, but it's just to show you the path.
I went to the QtVersions tab of QtCreator, added a new one and selected the above qmake.
QtCreator says:

Qt version is not property installed, please run make install

Why? I mean, what does this error imply? What is it looking for that it doesn't find?

After fixing this (hopefully!) I need to create the Kit. As sysroot I need to select tmp-glibc/sysroots-components/cortexa7t2hf-neon-vfpv4/qtbase?

Hi,

Did you try to run that qmake version directly in your command prompt ?

@Mark81 I don't know if it's possible to do what you currently try.

But it is possible to build a SDK: bitbake meta-toolchain-qt5. That gives you an installer that can be used on different workstations to cross-build Qt5 projects.

At least that's how we do it.

It's building right now. At the end (it's going to take many hours...) I will give a feedback. Thanks!

Unfortunately, it tries to build qtwebkit and fails, but I don't want it.
So I edit the file meta-qt5/recipes-qt/packagegroups/packagegroup-qt5-toolchain-target.bb removing the modules I'm not interested into. Then,

bitbake -c clean meta-toolchain-qt5
bitbake meta-toolchain-qt5

but now it returns a lot of errors that weren't there on the first "baking":

And worst, it still tries to build qtwebkit! Isn't the clean command enough to rebuild the package?

@Mark81

Yocto is a monster. Honestly, I don't know the correct way to do so, but to get a really clean try we remove the following directories: sstate-cache tmp-glibc deploy/ipk cache

Than start to rebuild.

Mark81

@aha_1980 thanks. I'll do it.
Just to be sure: it's ok my edit to avoid the building of qtwebkit?

I'd say yes. But I'm still learning Yocto on my way, and the way is hard.
