[JHBR]

Hi

I have successfully built Qt 5.8 for my Raspberry Pi 3 both native on the Pi and with Cross-Compiling following the well-known ELGFS tutorial ( https://wiki.qt.io/RaspberryPi2EGLFS ).

However, this has been without QtWebEngine to save time and size. I have now realised that I need QtWebEngine, but when I try to build it I get the following error:

QtWebEngineCore: created fwd-include header(s) for <srcbase>/src/core/api/ { qtwebenginecoreglobal.h (1), qtwebenginecoreglobal_p.h (1), qwebenginecallback.h (2), qwebenginecallback_p.h (1), qwebenginecookiestore.h (2), qwebenginecookiestore_p.h (1), qwebengineurlrequestinfo.h (2), qwebengineurlrequestinfo_p.h (1), qwebengineurlrequestinterceptor.h (2), qwebengineurlrequestjob.h (2), qwebengineurlschemehandler.h (2) }

As you can see, this output is from building it natively, but I get the same "gyp: name 'arm_thumb' is not defined while evaluating condition 'arm_thumb==1' (...)" when cross-compiling on an Ubuntu x64 VM.

Searching for this error, I found this thread: https://forum.qt.io/topic/77843/how-to-build-qt-for-raspberry-pi3/18 , but none of the actions taken there has helped.

Any help to understand this error is appreciated!

Edit: Bad output paste

[JHBR]

Below is the output from make during the same error when cross-compiling (here compiled as a single job to prevent cluttering of the output from other threads)
