2.35-r0: glibc compatibility regression due to removal of /lib64 #181

Open thotypous opened 2 years ago

thotypous commented 2 years ago

Programs which used to run normally with the 2.34-r0 release are broken after ddfe092f3d91c19f6cf8cb9f2938e088db4bfa8f.

I'm not sure how this could be fixed, since abuild now fails if the package contains /lib64 (otherwise you would not have removed it in ddfe092f3d91c19f6cf8cb9f2938e088db4bfa8f, of course)

>>> ERROR: glibc*: Packages must not put anything under /lib64, use /lib instead
>>> ERROR: glibc*: prepare_subpackages failed

but restoring the link from /usr/glibc-compat/lib/ld-linux-x86-64.so.2 to /lib64/ld-linux-x86-64.so.2 fixes the issue.

Please see some examples below:

/ # apk add dell-cctk

and starting again from a fresh system in order to get more verbose error messages:

The same as #175 and #176.

@thotypous: Would you please provide a minimal example Dockerfile which demonstrates the problem you're experiencing it. Without that I am unable to investigate this matter further.

Similar reprod Dockerfile at https://github.com/sgerrand/alpine-pkg-glibc/issues/176#issuecomment-1507914131

I'm not using Docker. I'm running Alpine on bare metal. This is the affected package: https://gist.github.com/thotypous/219170b3099c2694cfb4918f2e56fcb9

For others, if this helps, we have updated our Dockerfile to recreate the missing symlink after installing the glibc package:

RUN set -eux; \
    version=2.35-r1; \
    wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub; \
    wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/${version}/glibc-${version}.apk; \
    apk add glibc-${version}.apk; \
    rm glibc-${version}.apk; \
    if [ ! -e /lib64/ld-linux-x86-64.so.2 ]; then \
        mkdir -p /lib64; \
        ln -s /usr/glibc-compat/lib/ld-linux-x86-64.so.2 /lib64/ld-linux-x86-64.so.2; \
