  • Bug#1099885: jpeg-xl: FTBFS due to undefined reference when linking tes

    From Julian Wollrath@21:1/5 to All on Sun Mar 9 12:20:01 2025
    Source: jpeg-xl
    Version: 0.11.1-1
    Severity: normal
    Tags: ftbfs

    Dear Maintainer,

    the package in experimental fails to build (see e.g. https://buildd.debian.org/status/fetch.php?pkg=jpeg-xl&arch=i386&ver=0.11.1-1&stamp=1739052249&raw=0).
    While I it is probably not the best way to fix it, not enabling LTO
    makes it build for me.


    Best regards,
    Julian

    Thank you for figuring out a workaround. I pushed the requested change.

    I originally opted into LTO because Ubuntu enables it by default and
    it allowed us to synchronize the symbols file more easily. But I
    pushed a commit to mark the additional symbols as optional.

    I am surprised that this issue only affected Debian (Experimental?)
    but didn't affect Ubuntu 25.04 which is fairly similar.

    I made a very late request now to start the jpeg-xl 0.11 transition.
    It overlaps the ongoing icu 76 transition so I don't know whether the
    Debian Release Team will give us permission.

    Could you try reporting the LTO issue upstream? https://github.com/libjxl/libjxl/issues

    Thank you,
    Jeremy Bícha
