Hi there, It's me again with my 32bits build on 64bits Linux...
I have successfully build all of Qt-5.6 and Qt-5.9 (inc. webengine) in a i386/Ubuntu-16.04 docker container (mainly following https://www.ics.com/blog/how-compile-qt-source-code-linux). Now I would like to do the same in a amd64/Ubuntu-16.04 docker container. What I did is postfix all '-dev' packages from the build above with ':i386' (with a single exception: libgcrypt11-dev:i386 since it conflicted with libgcrypt11-dev). This way I can build all of Qt-5.6, except QtWebEngine. QtWebengine doesn't build due to a bunch of 'Unmet dependency'. First of all as all dependencies are installed, i suspected the probing itself and especially pkg-config. It turns out that to build a 32bits version of QtWebengine on amd64/Ubuntu-16.04, one has to install pkg-config:i386, which conflicts with pkg-config, here is the log: After configuring, building and installing Qt: # cd qtwebengine # rm Makefile # qtwebengine build was skipped # /qt-everywhere-opensource-src-5.6.3/qtbase/bin/qmake -spec linux-g++-32 qtwebengine.pro -o Makefile && make Running configure tests Checking for khr... yes Checking for libvpx... no Checking for snappy... no Checking for srtp... yes System zlib or minizip not found.

Is it a bug in Qt/webengine source? Why QtWebengine doesn't see the i386 -dev packages unless i install pkg-config:i386 (which breaks things)? Or is it a problem with Ubuntu?
