    @Gutemberg said in Building Qt for ARMv6l:

    __kernel_cmpxchg64

    Does this happen with a plain C++ hello world application without Qt?
    Here something about this issue: http://uhurumkate.blogspot.de/2014/07/a-newer-kernel-is-required-to-run-this.html
    It should work with kernel >= 3.1

    @jsulm nop, other c++ apps ran just fine on the device. Only with Qt the problem happens...

      Hey guys, does anyone has any idea how to workaround this issue (except by upgrading kernel since it is not possible)?

      We really want to buy Qt but we are struggling with this major blocker.

      Thanks!

        @Gutemberg GCC < 4.7 could help. Did you check the link I provided? There are several suggestions which can help:

        • Enabling arm v7 hard-float might solve your problem (it solved mine).
        • Using -mfpu=vfp and -mfloat-abi=hard might solve your problem (i didn't try as armv7 was desired).
