Bug 130361 – Cant reemerge glibc-2.3.5-r2

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Stefan Salewski 2006-04-18 06:59:30 UTC]

Yesterday I have modified my five months old Gentoo-AMD-64-installation to use UTF-8 character encoding as described at www.gentoo.org. I have noticed that the suggested reemerging of glibc fails. It is my strong believe that I have not done something evil with my gentoo box, so its looks like an serious gentoo bug. I found some reports of similar bugs, but no solutions. My own knowledge about Linux and Gentoo is not deep enough to find the reason. Here is the output of "emerge --info" and some error messages of "emerge glibc" from file config.log. The complete file config.log is available at http://www.ssalewski.de/config.log.

emerge --update --deep world

breaks trying to emerge fresh stable glibc-2.3.5-r3
with same messages as before.

I have no idea what is wrong with my system.

Logfile of emerging glibc-2.3.5-r2 is still available at
http://www.ssalewski.de/config.log.

Thanks

Why did you reopen this bug? The original one is still open...

Well, this serious bug still exits, I have no idea about the reason for this bug, I fear that this bug may crash my system in the long term and force me to a complete reinstall, and I am not sure if the title of Bug 129141 "cannot compute sizeof (long double)" is the perfect description of the bug.

Before the message "cannot compute sizeof (long double)"

there are a few other error messages in file config.log
for example

configure:3152: checking how to run the C preprocessor
configure:3187: x86_64-pc-linux-gnu-gcc -E  conftest.c
configure:3193: $? = 0
configure:3225: x86_64-pc-linux-gnu-gcc -E  conftest.c
conftest.c:10:28: ac_nonexistent.h: No such file or directory

Maybe an important package containig file ac_nonexistent.h is missing on my system?

Thanks

Compiling the latest kernel kernel-x86_64-2.6.16-gentoo-r6 with enabled IA32_Emulation (CONFIG_IA32_EMULATION=y) solved this problem for me.
See my remarks in bugreport 129141 for a longer explanation.

Best regards
