 Posted: Mon Sep 04, 2006 3:15 pm Post subject: glibc upgrade and the death of GCC |
 |
|
Just updated glibc as part of a regular wmerge -uDav world. Now GCC is failing with
| Code: | checking for C compiler default output file name... configure: error: C compiler
cannot create executables |
Any way around this....I cannot see any way of getting back to a working gclibc that will allow gcc to work.

I get exactly the same error. A solution would be great as i cant compile anything which, well ... sucks!
Maybe this thread can help you: https://forums.gentoo.org/viewtopic-t-493662.html
There are 2 possible solution on the last pages, but they didnt work for me 
Update:
my solution was this:
I grepped in /etc/env.d and found a 05binutils with links to old binutils.
And i corrected the symlinks inside these directories (they were pointing to old binutils as well):
/usr/i686-pc-linux-gnu/bin
/usr/i686-pc-linux-gnu/lib |

That other thread is not much help.....gcc was working fine, until glibc was upgraded....
if I try to compile a simple test program I get
| Code: | /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/../../../../i686-pc-linux-gnu/bin/ld:/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/../../../libc.so: file format not recognized; treating as linker script
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/../../../../i686-pc-linux-gnu/bin/ld:/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/../../../libc.so:5: syntax error
collect2: ld returned 1 exit status |
even after using gcc-config to swap between gcc versions.

nevynxxx: I found the solution to your problem (I got the same).
libc.so is wrong.
Old one:
| Code: | /* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily. */
OUTPUT_FORMAT(elf32-i386)
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a AS_NEEDED ( /lib/ld-linux.so/* GNU ld script |
New one:
| Code: | /* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily. */
OUTPUT_FORMAT(elf32-i386)
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a ) |
That fixed it. I have no idea why (in fact I just copied the libc.so from my brother), but it works for me, I hope it helps.
Greetings,
moHiJ

Fine to see that it worked for you too. But this is a bug, is it? And fixing it for you and me doesn't solve the problem.
Perhaps some one should do a bug report.

I have the same problem as you had. But I can not figure out what you exactly did to fix it. Could someone post a little more precise description, please?
Which file has to be edited or replaced?

Had the same bug & solution on amd64.
I just had to modify the new lines to reflect the correct arch ( /lib64 instead of /lib and
elf64-x86-64 instead of elf32... |

Ha! That was easy. Thanks a lot! I looked in /lib/ and found only binary code I can of course not read.
Now I am compiling again.
Bye!

| Everytime portage updates glibc i have to modify libc.so as posted above (like today). Quite annoying, why wasn't it fixed in the first place? Apparantly not everyone has this problem. |

Well, after posting this bug and some time wasting, because dumb me posted the wrong file, Vapier pointed me to another bug and the solution.
Just see bug #126032 or have a look at my bug (and watch my dumbness  ) and click the link.
The problem is binutils
| Mark Loeser wrote: | binutils-2.15.x doesn't work with >=glibc-2.4.
Run: binutils-config 2 (this assumes binutils-2.16.* is number 2, if not,
check binutils-config -l)
And then "source /etc/profile"
Everything should work fine at that point. |
Hope this helps,
moHiJ
