yocto boot2qt failing to compile qtwebengine in qt5.10 on Ubuntu 14.04



  • Hello,

    I'm trying to compile a b2qt-embedded-qt5-image on a Ubuntu 14.04 machine, but it fails when doing qtwebengine, with the following errors:

    | FAILED: v8_snapshot/obj/v8/v8_libbase/sys-info.o

    Does anybody know how to fix this issue?



  • @roberto_abl Ok I found a solution: I replaced gcc-4.8 with gcc-4.9 in Ubuntu 14.04 (default is gcc-4.8 in this distribution at the moment). Now it compiles.
