I think between GCC and I we made my box "Go boom"

Well I went to do emerge and found there was an issue with GCC and it needed to be upgraded as per:
http://www.gentoo.org/proj/en/base/amd64/2005.0-upgrade-amd64.xml

Hoewver when I get to this line:
make -f Makefile-profile_update-2005.0
I receive the following error:
checking size of long double... configure: error: cannot compute sizeof (long double), 77
See `config.log' for more details.

!!! ERROR: sys-libs/glibc-2.3.4.20040808-r1 failed.
!!! Function src_compile, Line 687, Exitcode 1
!!! (no error message)
!!! If you need support, post the topmost build error, NOT this status message.

make: *** [step6] Error 1

So then I tried following this thread:
https://forums.gentoo.org/viewtopic.php?t=281901&highlight=checking+size+double+configure+error+compute+sizeof+double+77

I can't seem to get past this one.

Any ideas would be great. I don't feel like rebuilding my box.

here is my make.conf
CFLAGS=""
CHOST="x86_64-pc-linux-gnu"
USE="multilib dvd dvdr ethereal faad ffmpeg glut imagemagick xine xorg-x11 \
--cups --java -kde -gnome --qt"
CXXFLAGS="${CFLAGS}"

TIA, Ken

Exactly the same problem... and no way so far to solve it

I had this same issue that I posted in another thread, no one posted a solution. It has to do with the configure script not being able to link it's test program due to ld not being able to find certain libraries. In the other thread it looked like Moonlight-Flower downloaded 32-bit binary libs and used them to make it work. I guess compiling a 32-bit glibc requires a 32-bit glibc already on the system? I downgraded to 2004.3 because I was tired of trying to fix this problem, maybe I'll try the upgrade again using the glibc binaries.

Just for $h175 and giggles I tried the emerge that "Trevoke" and guess what. Same thing. :-(

Is there any suggestions that someone with some expirience might be able to suggest??? I am no programmer, so I am quite out in the dark.
"Multiplexor" Could you post how you got out of it.

checking for strings.h... yes
checking for inttypes.h... yes
checking for stdint.h... yes
checking for unistd.h... yes
checking for long double... yes
checking size of long double... configure: error: cannot compute sizeof (long double), 77
See `config.log' for more details.

Ok, if there is no "known fix"for this issue, is this something I sould reinstall my box over? I was really hoping to avoid this.......
If I have to are there any precautions I can take so it doesn't happen again?

TIA

We need new precompiled 32bit glibc library that was floating around on the install mirrors under the 2005.0 profile directory. It was bundled with the 2005.0 switch profile script. It's not on the mirrors anymore and obviously we need it.

Cheers,

Luke

The error was self explanitory.

copy (not move or trust profile script) too two copies of the libs in /emul/linux/usr/lib32.

# cp /emul/linux/usr/lib32/* /usr/lib32
/usr/lib32 is a directory NOT a symbolic link (see the 2005.0 instructions).

When glibc has been merged again delete the older files as you see fit.

Cheers,

Luke

I hope I'm not coming across as spammy or anything, as this is the fourth thread about this error I'm posting to, but it was damn frustrating for me not being able to find an answer to this. Hope this saves someone else the trouble.

Anyway: if you have an LDFLAGS line defined in your make.conf, nuke it and try emerging glibc again. Worked for me.

Hi all!

I had exactly this same problem, which I solved by emerging the real emul-linux-x86-glibc-2.3.4.20041102 package (not the fake emul-linux-x86-glibc-1000) and then following step by step the upgrading by hand section of the AMD64 2005.0 Upgrade Guide.

A question I have now: can I remove the /emul directory? It's still full of subdirectories and files but it seems now it's no longer needed...

Thanks, M.

This worked for me with emul-linux-x86-glibc-2.3.4.20041102 installed.
