Build qtwebengine for embedded linux

Iheb

Hi, I'm trying to build Qt 5.8.1 from source. I downloaded the source code and I run configure using this command :

./configure -release -opensource -confirm-license -device linux-s500-g++ -sysroot /mnt/lemaker/ -device-option CROSS_COMPILE=/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -prefix /opt/qt5-arm  -nomake examples -nomake tests

After that it shows me the list of configuration and asked me to run make then make install
When I run make I get this problem:

code_textmake[1]: Entering directory '/qt5/qtwebengine'
/qt5/qtbase/bin/qmake -o Makefile qtwebengine.pro

QtWebEngine will not be built.

I tried to change functions.pri as detailed in https://forum.qt.io/topic/59113/qtwebengine-embedded
Why Qtwebengine won't be built and how to build it.

Why Qtwebengine won't be built and how to build it.

Check the config.log file to see what is missing.

Iheb

hey @jsulm thank you for your quick reply. I checked the config.log file and found these errors:


```make[2]: Entering directory '/qt5/qtwebengine/tools/qmake/config.tests/libvpx'

And also this:

@Iheb You need to install libvpx and libvpx-dev I guess for your target device

Iheb

@jsulm yes I think that is the solution. However after installing libvpx and the dev package I get the same error: svc_context.h: No such file or directory I took a look in /usr/lib and didn't find the file. After a little search I found that the newest version of libvpx-dev doesn't have svc_context.h. I'll post the solution when I find it. Thanks

jsulm

@Iheb Did you install it in your sysroot (or synced sysroot after installation)?

Iheb

@jsulm I've installed it in my target device (LeMaker Guitar) and I'm using sshfs to get the board's rootfs on my desktop so I think it's synced.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/mnt/lemaker//opt/qt5-arm'.

@jsulm I managed to add the svc_context.h file in vpx and after running make I get this output:

Qtwebengine still won't be built and I get no errors in config.log file

@Iheb Please run configure from a clean state without artefacts from previous runs.

Hi @Iheb did you find a solution ? I want to know if webengine can be used on my raspberry pi .
