Sorry about the delay. You can find the glibc-2.26 compiled with powerpc64 at http://blackstar.xs4all.nl/glibc-2.26-ppc64-powerpc64.tgz

Hi Bas,

Thank you. Could you please upload the libm when you are finished with compiling? I would like to test it on my Cyrus board.

Thanks,
Christian

Hi Christian,

I am running into a similar problem with my T2080 (using an e6500). I'm currently rebuilding gcc to build for powerpc64 by default, eliminating those from being generated by default. Once that is done, I'll have to rebuild glibc with the new gcc compiler to update libm.

    Hi All,

    I use Debian Buster/Sid PPC64 on my Cyrus board with a P5020 SoC
    [1]. The E5500 fpu doesn't have a fpsqrt instruction. Does
    Debian's libm have support for emulation of the fpsqrt instruction?

    Thanks,
