Dear Peter, 

Thanks for testing it. As I would like to keep using the Qt 5.11.3. I would
like to find a solution with a gcc toolchain > 5 (webengine requirement)

- Using the one provided by RPI is not possible because it is 4.9.3
- Next I tried to use the buildroot toolchain, with gcc 5 (find attached my
defconfig). 

cp4_defconfig.cp4_defconfig
<http://buildroot-busybox.2317881.n4.nabble.com/file/t2824/cp4_defconfig.cp4_defconfig>  

Now it fails building qt5webengine, when:

./../../3rdparty/chromium/third_party/WebKit/Source/modules/indexeddb/InspectorIndexedDBAgent.cpp:1007:7:
warning: ‘blink::ClearObjectStore’ has a base
‘blink::{anonymous}::ExecutableWithDatabase<blink::protocol::IndexedDB::Backend::ClearObjectStoreCallback>’

This is a problem of the defconfig? The rpi 0 W maybe can not support the
qt5WebEngine? It is a problem with host (I am using Ubuntu 16.04)?

Kind Regards and thanks!

Rafa
