[Qtwebengine] "qmake -r" error -- unknowm model: webchannel

[Kevin Truong]

Hi,

I am trying to get qt webengine running on my laptop. I ran into some
issues and would greatly appreciate any help. I am following the
instructions from here:

https://wiki.qt.io/QtWebEngineHowToTry

On the last few steps, I had to run "qmake -r" on the qtwebengine
directory. This is the output:

SSL............................... Using system NSS
ICU............................... Using internal copy (Default, force
system ICU with WEBENGINE_CONFIG += use_system_icu)
FFMPEG............................ Using internal copy (Default, force
system FFMPEG with WEBENGINE_CONFIG += use_system_ffmpeg)
Proprietary codecs (H264, MP3).... Not enabled         (Default, enable
with WEBENGINE_CONFIG += use_proprietary_codecs)
Reading /home/kevin/workspace/qtwebengine/src/src.pro
 Reading /home/kevin/workspace/qtwebengine/src/core/core.pro
  Reading /home/kevin/workspace/qtwebengine/src/core/core_gyp_generator.pro
Project ERROR: Unknown module(s) in QT: webchannel

This error happened right after I installed WebKitGtk+ from here (
http://trac.webkit.org/wiki/BuildingGtk) and ran
"Tools/gtk/install-dependencies"
and "Tools/Scripts/update-webkitgtk-libs".

(I installed WebKitGtk+ because, previously, running "qmake -r" on the
qtwebengine directly resulted in an "unmet dependency: harfbuzz" error that
I tried to fix on my own via google, and the WebKitGtk+ page was the only
lead I could find that would supposedly fix that issue).

I am running on a (mostly freshly reformatted) Ubuntu 15.04 laptop.

Any help would be greatly appreciated! I would love to try out qt webengine.

Thank you for your time,
Kevin
