"C compiler cannot create executables" !??!

with me the solution was otherway round. i hav a pentium-m in my system and the new gcc supports the -march=pentium-m option. unfortunatly the live-cd does not use the correct gcc version and the error was so stupid that it took me a hell lot of time to notice that i had a non-supported architecture in the CFLAGS. used now -march=pentium3. it works but is a bit sub-optimal in the end.

I had the same problem durring bootstrapping at gettext.

Mine is a simple fix: wrong type of processor was set. Set it to -march=athlon64 and everything was fixed.

Everything was working fine for me until yesterday I did an emerge sync && emerge -u world and now for every package I get a similar output to this:

I've actually found as and all the binutils in /usr/i686-pc-linux-gnu/binutils-bin/2.15.92.0.2/ so as root I did

Help?

Having the *exact* same problem as BlastM. In the same circumstance, too. I thought for the new year I'd emerge sync && emerge -U world, and then it died rigth after it emerged the new binutils. I checked the /var/log/emerge.log to catch what it had done last.

Of course, I can't emerge binutils again because it can't find as.

Read the whole thread, and it sounded promising, but it seems that the gcc thing isn't an issue for me...I'm still using 3.3.4, and ld.so.conf, et. al. are looking fine.

Considering how close together these were, could this be an ebuild bug that was committed recently?

Anyone know how to fix it? I'm pretty good with Linux, but I admit total ignorance of creating ebuilds and managing things correctly when the ebuilds are buggy or break. Help?

I found the binutils in /usr/i686-pc-linux-gnu/binutils-bin/2.15.92.0.2/ so I symlinked them all into /usr/bin. Then I was able to emerge an older version of binutils, and the ebuild overwrote the symlinks with the new utils (according to an md5sum check on each of them).

Some programs stopped working, giving cryptic errors that I can't remember but it might have been about something they were linked against. So I set ACCEPT_KEYWORDS="x86" (which included the older version of binutils) and I did an emerge -uD world and went to bed.

When I woke up this morning, some package (I forget which, it didn't say, but it had something to do with timezones so it might have been baselayout) had failed installing with the following error:

It's probably worth mentioning that I'm on amd64.

I don't plan on changing any of my keywords. Gentoo is the first system in a long time that I maintain, and haven't had to wipe it clean with fresh installs. Obviously, it requires some manual maintenance now and then due to issues like this one.

Anyone know a place where a log is kept that tells you *exactly* what emerge did? I've been looking at /var/log/emerge.log, but it doesn't have detail enough for my troubleshooting.

OK, well, I'm going to keep working on this, but I'm not sure where to go. I guess I'll take a look at the ebuild files and start learning how to hack them. Not a bad way to start 2005, actually, I've been meaning to learn the portage system better...I guess this is a good opportunity.

Me too.

I have an Athlon 64 but I use ~x86 (or I'll be using x86 until the problems are sorted out) and -march=athlon-xp because I wasn't satisfied with the tradeoff of compatibility, stability, and the Just Works factor for an increase in speed that often was hardly noticable.

I think this is an issue in general with ~x86 and not just an Athlon 64 problem.

Update:

I grabbed a stage 3 install to untar and look at how it was set up. It seems that all that I had to do was simply symlink the binutils binaries over to /usr/bin.

I've since re-remerged kde and xorg, and lots of smaller stuff too. Everything is working great.

This sounds like a broken/buggy ebuild to me. Can anyone verify this?

BlastM · Posted: Mon Jan 03, 2005 5:08 am Post subject:

When I symlinked my binutils across to /usr/bin everything appeared fine.
That was, until I did an emerge -uD world and every binary on my system segfaulted.

Tell us how everything pans out.

rpdillon · n00b Joined: 16 Jul 2004 Posts: 50

Yes, but you then re-emerged an older version of binutils, which I think caused a problem for ya. I'm pretty sure we had the same problem, I just knew what NOT try to try when I went fiddling around, since you were kind enough to let me know your technique crashed and burned.

Hi, I've emerged gcc, but because I'm new too gentoo doesn't update but install and I've end up having 2 gcc (3.3.4 & 3.4.3-r1), then I wasn't aware of the correct steps to change gcc, and just did emerge -C gcc-3.3.4...VERY BAD... then I've read the forum and did the steps:

Hi,

i had the same problem with "C compiler cannot create executable" and found out that it was related to the binutils-2.15.92.0.2-r2 ebuild. After downgrading to binutils-2.15.92.0.2-r1 everything worked fine again.

I was also having this problem in addition to segmentation faults emerging various packages. I was unable to downgrade to binutils-2.15.92.0.2-r1 due to the "C compiler cannot create executable" problem. A sort of "Catch-22". My solution was to comment out CFLAGS and FEATURES in make.conf. Then I was able to downgrade. After restoring CFLAGS and FEATURES I've been able to compile several packages without problems. More testing is needed though.

I am getting the "configure: error: installation or configuration problem: C compiler cannot create executables" error too when trying to update gcc.

* sys-devel/gcc
Latest version available: 3.3.5-r1
Latest version installed: 3.3.4-r1

emerge -pvuD gcc
These are the packages that I would merge, in order:

I eventually get this error when actually trying to update:

I too tried all these steps (except 5):

https://bugs.gentoo.org/show_bug.cgi?id=71629 may shed some light on my problem, but still no solution

i followed all the tips in this thread,the 'as' problem went away but i'm still unable to emerge binutils, 'configure: error: installation or configuration problem: C compiler cannot create executables.' prevents me from emerging any package, I symlinked the binutils binaries, changed the values in ld... but I'm still unable to emerge ANY FUCKING PACKAGE. How do I emerge binutils with the livecd? before chrooting the emerge command is not found, and after chrooting emerge gives me the same errors probably of using the broken binutils. do i have to bootstrap?

note: i tried to run bootstrap with the livecd, guess what? same emerge erors. now the 'as' error appeared again. i don't want to recompile all the system again, I don't understand why commenting several things in make.conf leaded to a working compilation. I tried that and it didn't work. please help

thanks

OK, I've been struggling with this for a couple of days on my laptop.

I've re-emerged libtool, I've done

I came in this problem with this topic. (forum IT)

http://forum.html.it/forum/showthread.php?s=&threadid=778074

Still not work.
Do all that is written in this forum (the result in in the post up)

Something else??? :cry:

I wanted to add my experience with this error. For me it occurred during bootstrap. Turns out I had mistyped a compiler flag in make.conf. I had -ffast_mth when it should have been -ffast_math. I don't know why this matters but it did.

i had that error too...

my way "to it":

install a centrino laptop with gcc 3.3.5, upgrade that bastard to 3.4.3-r1... then optimized my cflags according to the "flying with gentoo thread" and either i or the author of it had a typo in his cflags..

i had an additional "s" in one of them.. removed it and its working again

Gentree · Posted: Fri Feb 11, 2005 1:50 pm Post subject:

Exactly the same here. Trying to install form bootstrap in a chroot env.

was using CFLAGS from existing gentoo , so included the recommended use of -mtune.

If this actually screws up bootstrap.sh it should probably be filtered by the script or the ebuild.

I am not aware that bootstrap is designed exclusively for use with a virgin system and an empty make.conf.

It is not sufficent to add -mcpu , you need to remove -mtune.

If feel a bug report coming on.
