Package: libc6-dev
Version: 2.37-12
Severity: normal
X-Debbugs-Cc: pkg-qemu-de...@lists.alioth.debian.org
When building a statically-linked application with -static-pie flag
(which is not supported on every platform), on i386 where it seems
to be supported (at least -static-pie flag is accepted), the link
fails like this:
/usr/bin/ld:
/usr/lib/gcc/i686-linux-gnu/13/../../../i386-linux-gnu/libc.a(memset_chk-nonshared.o):
unsupported non-PIC call to IFUNC `memset'
/usr/bin/ld: failed to set dynamic section sizes: bad value
This can be observed, for example, here:
https://buildd.debian.org/status/fetch.php?pkg=qemu&arch=i386&ver=1%3A8.2.0%7Erc1%2Bds-1&stamp=1700774780&raw=0
There are some architectures where -static-pie build is supported
and works (eg amd64, arm64, s390x), where it is not supported at
all (most other architectures), and where it is supported but does
not work, and this is i386, - this is what this bug is about.
I guess it needs to be either rejected entirely as unsupported, or
to be working.
Does it make sense to enable pic build of glibc on i386 architecture?
Right now I'm not sure what to do with qemu which is FTBFS on i386
due to this.
Thanks,
/mjt

i386 is not really used anymore, so this went unnoticed until now. It
appears that the issue is fixed in glibc 2.38, probably as a side effect
of other changes. I am not sure it is worth backporting the related
changes to 2.37 in sid, with the risk of breaking things. Anyway, the
goal is to push glibc 2.38 to sid in the next weeks.

It seems that you disabled PIE on i386 in the latest qemu upload. Could
it be kept like that until we get glibc 2.38 in sid?
