aarch64 Qt5.7 for Odroid-C2 cross-compilation problem.

[noname123]

Hi, I'm trying to cross-compile Qt5.7 for Odroid-C2 (aarch64)

compilation stopped on qjsonvalue.cpp

int QJsonValue::toInt(int defaultValue) const
{
    if (t == Double && int(dbl) == dbl).
        return int(dbl);
    return defaultValue;
}

error log is

Hi,

Like suggested on the error message, you should get in touch with the Linaro folks.
