Bug 935898 – sys-libs/glibc-2.39-r6: 829MB /usr/lib64/libc.a on catbus.sparc

• Status: CONFIRMED
• Product: Gentoo Linux

[Description Arthur Zamarin 2024-07-12 13:50:04 UTC]

From random looking at what takes space on "/" filesystem of catbus.sparc devbox, I noticed this:

> # du -sh /usr/lib64/libc.a 
> 829M    /usr/lib64/libc.a

Meanwhile on my amd64 PC, it is just 23MB. It would be interesting to know (and maybe report upstream?) why such a big difference.

I actually saw this on amd64 earlier with:

before: 360M libc.a
after `strip`: 3.7M libc.a

I wonder if we're not stripping static libraries correctly in Portage (might only show up with splitdebug or something).

For kicks, I stripped the libc.a on catbus and got:
catbus /etc/portage # ls -hal /usr/lib64/libc.a
-rw-r--r-- 1 root root 829M Jun 19 16:51 /usr/lib64/libc.a
catbus /etc/portage # strip /usr/lib64/libc.a
catbus /etc/portage # ls -hal /usr/lib64/libc.a
-rw-r--r-- 1 root root 3.2M Jul 19 18:19 /usr/lib64/libc.a

which makes me think something is off.

I saw https://lore.kernel.org/all/[e-mail]/ by chance earlier, might be interesting to compare their implementation in openembedded...
