"C compiler cannot create executables" !??!

idl

I'm just trying to configure mozila using https://forums.gentoo.org/viewtopic.php?t=20942 but i get the error:

checking for gcc... gcc
checking whether the C compiler (gcc m4 ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.

i'm sure i saw someone talking about this before on the forums but i cannot find it!

Thankyou!

I had exported my CFLAGS wrong somehow.. you need to make sure its the correct syntax

I had a similar problem when doing an upgrade via "emerge -u portage". When it tried to compile a pre-requisite package (in this case Gawk), I got the same error message.

I found that apparently it had updated the C++ libraries and my paths (specifically in /etc/ld.so.conf), were now wrong. In order to fix it I had to:

1) edit /etc/ld.so.conf to fix the gcc-lib path (in my case it went from 3.2.3 to 3.3.3.

2) run "ldconfig" to set the proper library path

3) edit /etc/env.d/05gcc and change all the paths to the new version.

If you don't do steps 1 and 2 you won't be able to run emerge again. If you don't do step 3, it will undo your changes from step 1 when you run emerge again.

Hope this helps...

This is usually caused by doing an emerge world that includes a gcc upgrade. What happens is, the new gcc is compiled, but the ebuild fails to switch your system to the new compiler. Before trying any of the solutions above, try doing:

brand new box. stage3 tarball, 2004.3

I get to the end of my build and runto this:

C compiler cannot create executables, for my install of the latest grub..

in looking at my config.log ...

here is a snippit

Had the same exact problem as imbiea. I ended up just installing sys-boot/grub-0.94-r2 instead. Seems to be an issue with the 0.95 grub, but I need to get this laptop going too much to take the time to find out exactly what the culprit is. Seems to be a package-specific issue.

Agreed. I figure it's a package issue, but I dont' recall having this issue two weeks ago with the same version of grub and using stage3 2004.2 tarballs. So I figure it's something different in the complier.

I'm going to try to stage a box today, and use the 2004.2 tarball... I'll post it back here.

I'm going to be trying this out tonight I have a similar problem with the 2004.3 GRP. I ran my first gentoo install last night (So I was assuming I'm the problem) and got this error message on the emerge of all three possible sysloggers. That said the install of grub worked fine.

I held my breath, hoped that the syslogger wasn't necessary for boot, configured grub and rebooted. ... and found that it booted fine.

I'll be trying out some of these suggestions above tonight but I find it odd that a newbie following the doc(Edit: Maybe not) to the letter would hit a major bug like this.

Non standard things I did:
-Downloaded Kernel 2.6.8.1, a EPIA premade .config and the matching epia1 patch
-Set the march to C3-2 (+ other normal looking options)

I had the problem again, but I was aware of the cause:
I was trying to test if a given env variable would work if declared inside make.conf (CCACHE_DIR) instead of /etc/profile.

IMHO in many cases these weird errors are caused by syntax errors in make.conf, so before trying anything else checking make.conf would be a good idea.

As this seems to be a recursive topic setting this thread as 'sticky' would perhaps be a good idea, we could also list all solutions:

(this is not the same case, but it's related, and if GCC is wrong libtool can also fail)

try 'unset GCC_SPEC' or something (I didn't remember) It cause gcc not work correctly after switched to new gcc

try export to see that environment variable.

i noticed that in the gcc 3.4.3 ebuild, there was an issue with running fix_libtool_files.sh, so after merging it i ran

I solved the problem that I had. I was using the EpiaWiki recommended march of c3-2 which seemed to be causing me issues. They specified a minimum gcc version which I met. I have switched back to the next nearest value for my C3 processor (686) and it now works fine.

Though an emerge kde took 2 days to compile, I guess thats fine

similar problem here... but during bootstrapping process.

using the livecd and aa current stage1 image i can get till bootstrapping but just after launching it the entire thing breakes with an error (i can't post from that pc so i need to somehow describe what it is).

the thing tells me that 'gcc can not create executables' and this happens in the gettext package, the first package compiled (furst is linux headers but they are just unpacked).

i looked through the posts and all but have no idea what can happen. i also reformatted and tried all but to no avail. i installed gentoo a couple of times thus it's not a noobie problem. it must be something with the latest 2004.3 image (as i think the last one i did was with the 2004.2 image).

is this a confirmed problem or am i shitty unlucky?
