[mandlakoteswar2011]

Hi All,

Am getting this error in Qt 5.10.1 ===========>Project ERROR: Unknown module(s) in QT: webenginewidgets"

I added in .pro file Qt+=webenginewidgets but still am getting this error.

can you please give some direction regarding this issue.

Thanks

And it should not be like this :
Qt+=webengine widgets

Thanks for reply..

if i included same statement in .pro file =>Qt+=webengine widgets

am getting the same error..

[Lesiok]

OK, Qt += webenginewidgets is correct. It turns out that you do not have this module installed.

I did Qt 5.10.1 configuration below steps. using qt-everywhere-opensouce-5.10.1.tar.xz..

sudo apt-get install bison build-essential gperf flex ruby python libasound2-dev libbz2-dev libcap-dev \
libcups2-dev libdrm-dev libegl1-mesa-dev libgcrypt11-dev libnss3-dev libpci-dev libpulse-dev libudev-dev \
libxtst-dev gyp ninja-build

I Configured QtWebengine module ===> ./configure -webengine-pulseaudio -webengine-alsa -webengine-embedded-build -webengine-pepper-plugins -webengine-proprietary-codecs -webengine-spellchecker -webengine-webrtc
