I just found the solution to my above problem. I had qt in my USE flags, which is reliant on X11 (which I don't have installed -- console ftw.) I just changed it to -qt, and it compiled. Good luck with php

Another one to add to the queue:

I followed the make.conf.example advice and, for my new dual G5 (ppc64, stage-2 install), set CFLAGS:

Code: Select all

 CFLAGS="-O2 -pipe -mcpu=970 -mtarget=970 -maltivec -mabi=altivec"

The error popped up on me trying to do the initial

Code: Select all

 emerge --emptytree system

Well, it turns out that the problem goes away if I remove -mcpu and every argument thereafter from CFLAGS. Too bad, it might have been nice to use those. I tried -mtune rather than -mcpu, to no avail. -mtarget=970 alone doesn't even work.

FWIW.

I tried most of the methods and for some reason after i rebooted and logged in as root instead of using SU
it worked.

I had this same error msg, but apparently another error. Since this was the thread I came across when searching, I thought I'd post the fix I found (by coinsidence) on bugzilla (http://bugs.gentoo.org/show_bug.cgi?id=86123):

Code: Select all

rm -f /usr/lib32
ln -s ../../emul/linux/x86/usr/lib /usr/lib32
FEATURES=-sandbox emerge gcc

I was halfway through a reinstall on another partition when I found this solution, so I hope this'll help someone else.

I had the error too; in fact it was binutils links in /usr/i686-pc-linux-gnu/bin that were pointing to /usr/i686-pc-linux-gnu/binutils-bin/2.16 ; or in facts real binaries were in /usr/i686-pc-linux-gnu/binutils-bin/2.16.1

So just do:

Code: Select all

rm -rf /usr/i686-pc-linux-gnu/bin/*
for file in /usr/i686-pc-linux-gnu/binutils-bin/2.16.1/*; do ln -s $file /usr/i686-pc-linux-gnu/bin/; done

(of course dont forget to change this to match you binutils version)

after trying to fix /etc/env.d/05gcc and gcc-config of course

hope it can help some people (when typing this binutils-2.16.1 was just released in ~x86 profile)

pounard Yes, after updating binutils 2.16.1 I got the same problem. Thanks for the solution

.

pounard · Post by **pounard** » Mon Jun 13, 2005 1:40 pm

i did this but i think binutils-config can do this on is own too..
i didnt tested, if anyone does; dont hesitate to answer :}

Ran into this problem too! Thanks for the solution!

centic · Post by **centic** » Mon Jun 13, 2005 1:52 pm

For fixing this cleanly, you should do

Code: Select all

binutils-config i686-pc-linux-gnu-2.16.1
source /etc/profile

look at http://forums.gentoo.org/viewtopic-t-34 ... art-0.html

I had to read 4 pages of stuff that didnt work until you came around

That was clean, easy and best of all.... IT WORKED!!

Thx.

I can verify that after installing binutils-2.16.1, my binutils profile was not updated to point to 2.16.1. It remained pointing to 2.16. Simply using binutils-config to change it and running source /etc/profile fixed everything as mentioned above.

mrhenrik · Post by **mrhenrik** » Mon Jun 13, 2005 3:43 pm

Finally!
I became a member of this Forum about 3 minutes ago just to say THANK YOU!
after browsing around all day i finally found the binutils error.
I had been trying to downgrade binutils - but "C compiler cannot create ..." wouldn't let me
and i could upgrade/downgrade gcc - because "as" couldn't be found...
Anyway thanks!

I failed to notice after the binutil upgrage that it failed to switch profiles. your tip seems to fix issues

yamakawa · Post by **yamakawa** » Mon Jun 13, 2005 5:01 pm

i did

/usr/bin/binutils-config -d i686-pc-linux-gnu-2.16.1

according to a solution in a bug report in bugzilla.
anyway, thank you all!!

I'm the new guy. Thought I'd say hi and throw in .02 about this:

Do we agree that gcc upgrading is the trickiest quirk in the whole gentoo universe? I count about 4 threads devoted to it, some long ... mine was fixed by the short one

I had things broken another way so that my C compiler wouldn't make executables.

I ran binutils-config (which I think is new on my system) and it wasn't set to anything. /usr/bin/ld didn't exist. So I did "binutils-config 1" and then everything was just fine and /usr/bin/ld existed again.

My etc-update wants to update 100 or so files so maybe it's my fault. Now, if emerging binutils-config had some super important warning notice after it completed merging (and many packages do), I can't take responsibility for that. Portage should compile these and keep them in a log or something.

Darknight · Post by **Darknight** » Mon Jul 11, 2005 9:00 am

It happened to me today. I had changed "mcpu=pentium4" to "mtune=pentium4" in make.conf. When I changed back it worked ok... dohhhh

No, I have changed gcc several times and never had any real trouble. However, I have never been able to gat an ATI gx card to work - and I've spent days trying.

BTW the gentoo ATI thread is in the guiness book of records.

Once you have gone through all the other suggestions in previous post then try this:
Code: Select all
binutils-config --amd64
then
Code: Select all
source /etc/profile

Worked for me too... amost, I did a

Code: Select all

binutils-config 1

as it didn't work with --x86 for me. Now at least stuff is compiling. Goodie!

Anyone here encountered the "C++ compiler cannot create executables" error while doing a fresh install of Hardened Gentoo (i.e. SELinux) lately? If so, how did you get solve the problem?

I'm in such a situation. I get the "C++ compiler cannot create executables" when I try to bootstrap the system (i.e. run scripts/bootstrap.sh). I've checked and rechecked my make.conf file, tried different options and even tried commenting out the CFLAGs and other variables in make.conf altogether but the bootstrap keeps failing while trying to compile Python early on in the script. I've used gcc-config as directed in the threads above to verify that the compiler is correctly chosen/referenced too. I would have used the binutils suggestion but I can't compile/emerge it since ncurses is among its dependencies. ncurses in turn complains and errors out during emerge/compilation because it can't find a C++ compiler and cannot create executables...

I posted http://forums.gentoo.org/viewtopic-t-361737.html yesterday about the problem but haven't gotten a reply yet...

WetSpot · Post by **WetSpot** » Wed Sep 07, 2005 4:28 pm

Or, as was my case, I simply borked my /etc/make.conf by not using the -w option with nano while editng the USE flags.

Thus $CHOST was unavailable when required

when i try and emerge gaim it bombs out when emergeing gtk+.
gives me c complier cannot create executables. I've tried the things listed in this topic and nothing seems to work for me.
I have a Amd64 Athlon xp 3500 with gentoo and a 64 bit kernel.

"C compiler cannot create executables" !??!

Thanks for the solution!!!
