Qt 5.5.1 on openSuSE LEAP 15.1 - assertion failed: type_must_have_known_encoded_size



  • OS is openSuSE LEAP 15.1 x86 64-bit with gcc 7.4.0.

    Qt 5.5.1 configure is:

    ./configure -qt-sql-psql -qt-sql-sqlite -qt-zlib -qt-libpng -qt-libjpeg -qt-xcb -nomake examples -skip qtwebengine -opensource -confirm-license

    Compilation failed here:

    Same exact source compiled fine on CentOS 7.4 with gcc 4.8.5. I presume the problem is related to using a much newer compiler version.

    Anyone run into this issue? Using a newer Qt version may not work for my purpose since Qt 5.5.1 is required by the product I hope to compile once Qt is installed.
