Hi,
I tried building qt for asus tinker board according to this qt blog post:
https://blog.qt.io/blog/2017/05/03/qt-git-tinkerboard-wayland/

I checked out version v5.9.1 (i don't which version is used in the blog post) from git repository and tried to build, the configuration seems ok as:

I can confirm that i could build with same configuration and the same sysroot for Qt 5.8.0

Whats the problem with the 5.9.1 source?

Hi,

From the blog post, it seems they are using the dev branch.

Since you are using the git sources, you should update it, currently it's the 5.9.2 release that you should have from the 5.9 branch.

Thanks for your reply Sgaist.
I tried to build the 5.9 branch which is currently on 5.9.2 (although there isn’t any v5.9.2 tag) again the same problem happens.
but building from dev branch seems to solve the problem.
I tried to find the patch to apply but there are lots of commits behind so i think most logical way is to wait for 5.10.0 stable release because i don’t want to take a risk and use a non stable build

SGaist

The 5.10 branch has just been created, you can build and test it.

Did you ever get Qt working on your Tinkerboard.

As I am having issues following the blog guide!
