Package: file

Hello,

on sh4 many package builds are terminated in dh_shlibdeps stage due to:

dh_shlibdeps: file -e apptype -e ascii -e encoding -e cdf -e compress -e tar <<shared_object>> returned exit code 1

Observed at least in build logs of libssh [1], apt [2] and cod-tools [3].

Best,
Andrius

Built on sh4-do-01.buildd.org


Long story short: The file(1) program caused the build errors on sh4 for
several packages. After *many* hours of digging I found the pread64
system call used by libmagic isn't properly translated when using the
stretch version of qemu-user-static (1:2.8+dfsg-6+deb9u5). The
buster/sid version has upstream's fix¹, and I can confirm file(1) will
work as exepected then. So, not a bug in the file package, closing.

The thing that puzzles me: James Clarke (jrtc27, cc:'ed) stated the
buildds use a manually built and fairly recent qemu version. These two
bits of information don't match.

As I neither have access to the buildds nor am interested in getting
one: Can you please check the problem is really fixed there? Should
be as simple as running "file /bin/ls" in a qemulated sh4 chroot.

Expected result: /bin/ls: ELF 32-bit LSB executable, Renesas SH, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, BuildID[sha1]=bc61964767543a3ac5b756454ac96634c24a9f1b, for GNU/Linux 3.2.0, stripped

Broken: /bin/ls: ERROR: error reading (Invalid argument)
(also, non-zero exit)

Cheers,

    Christoph
