QT WebEngine 5.9.x - Cross Compile i.MX6

  • Hello gents,

    I am trying to compile QT5.9.1 for my i.MX6 target and I am having problems in getting it build. I have no problems in cross compiling QT for my target without the QtWebEngine support. Also a cross build of Qt 5.7.1 works without any compile errors or issues. But starting with Qt 5.8.0 up to 5.9.1 cross building the QtWebEngine doesn’t work anymore. Here are my configuration and the error message I get. Any help appreciated. Thanks in advance.

  • After years of not getting an answer to my question, I finally managed to resolve the matter myself. So for all the folks out there facing the same issue, the solution is as simple as dumb: You need to compile everything on a 32-Bit host!

    As a matter of fact, the QTWebEngine build system somehow is tailored for 32-Bit compilation. Simply installing the multi-arch packages on a 64-Bit system is not sufficient enough, it really needs to be a 32-Bit machine. In my case, I successfully built QT5.15.2 under Debian Stretch 9.13 32-Bit without any issues. I consider this case closed.
