Unable to build QtWebengine on Raspberry Pi 3

I am trying to build QtWebengine on Raspberry Pi 3. Qt base and other components was successfully built, but when I try to run qmake in QtWebengine directory I get this:

pi@raspberrypi:~/qt5/qtwebengine$ /usr/local/qt5/bin/qmake

WARNING: Thumb instruction set is required to build ffmpeg for QtWebEngine.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/usr/local/qt5'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.


 
pkg-config is required
QtWebEngine will not be built.

fontconfig fontconfig-dev are installed(the same as dbus and nss). What is the problem?

Hi and welcome to devnet,

Take a look at the Required system libraries list. They are all missing.

artsin

Hi! Thank you for your reply. As I said fontconfig and fontconfig-dev are installed, but qmake does not see them. The same is with dbus-1-dev and nss. Why?

artsin

Moreover, I run this on my system:

$ pkg-config --libs fontconfig
-lfontconfig -lfreetype

pi@raspberrypi:~/qt5/qtwebengine$ pkg-config --cflags fontconfig
-I/usr/include/freetype2

pi@raspberrypi:~/qt5/qtwebengine$ ldconfig -p | grep fontconfig
        libfontconfig.so.1 (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libfontconfig.so.1
        libfontconfig.so (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libfontconfig.so

It looks like that with fontconfig everything should be ok...

Check the build logs, you'll see the where the errors happen.

You are also missing pkg-config.

Note that once you installed these package, you should launch configure from a clean state. The best would be to do an out of source build so you can easily nuke the build folder to start fresh.

artsin

How can I miss pkg-config if I just run it from the command line? Also, I've not installed these dev libraries AFTER configure of QtBase, they just were already installed.

SGaist

Hence taking a look at the logs generated during the configure phase might give you the information you need about that.
