Bug 163975 – sys-devel/gcc-4.1.1-r1 emerge fails (probably due to linking problem with libc)

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description tomas bonnedahl 2007-01-26 20:23:20 UTC]

Tried to update my system that hasn't been updated for a couple of months, I finally reached the update of GCC, which failed. 

I've tried using the common 'emerge -u gcc', I have also followed the guide at http://forums.gentoo.org/viewtopic-t-494331-highlight-gcc+64.html and the guide at  http://www.gentoo.org/doc/en/gcc-upgrading.xml#upgrade-general without success.

I think the problem lies with some 32/64bit problem. The system should be multilib, but 'ld' believes that "libc" is incompatible. Just before the error with ld, we can see that alot of 32bit stuff is happening. So, I believe that ld shouldn't use /usr/lib/gcc/x86_64-pc-linux-gnu/... because /usr/lib is a symlink to /usr/lib64 which is the 64bit version.

This could all be wrong of course, and it could be just my system this appears on. If it is, I'm sorry.

Reproducible: Always

Steps to Reproduce:
1.emerge -u gcc 
2.
3.

Actual Results:  
Error from 'ld', result can be seen on url.

Expected Results:  
gcc successfully emerged.

Please, don't refer to third party links like pastebins when reporting bugs; makes bugs useless in days. Post/attach all the relevant info here and reopen then.

Reopening the bug. I removed the URL with information and attached a text file instead.

How long did you not upgrade it? Did you switch profiles before doing this upgrade? If yes, which one was the old one?

I installed the box in August/September 2006 with profile 2006.0. I did try to upgrade it using the old profile, that didn't work so I thought I upgrade the profile to 2006.1/desktop, but the same err came. 

Nothing is special with this box, just regular Gentoo desktop user with a AMD64 processor.

I have some new information regarding this "bug". 

It seems gcc-3.4.6 was built using --disable-multilib (probably with a no-multilib profile). As I said I tried to change the profile to 2006.1/Desktop and reemerge gcc with multilib support but without success.

I believe this bug is only happening on my system and hence shouldn't be here. I will however be greatful if someone knows how to fix this without having to reinstall.

Indeed, it's not a bug.

Short answer: There is no way, unfortunately.
Long answer: There is no way, unfortunately. However, you can _try_ to unpack a stage3 over the old system, revdep-rebuild, then update again, then revdep-rebuild again. However, this is still not safe and pretty time-consuming, you might be better of with a complete reinstall.

Thank you and sorry for the bug post. I think Ill try it before the re-install.
