can't compile; configure won't complete: "C compiler cannot create executables"

pbhj · 04-17-2007, 07:34 AM

Ok I've tried to compile a couple of things (kaffeine, kipi-plugins) now after upgrading to gcc-4.1.2 and nothing gets past the configure:

Error in console:

Code:

This is the "C compiler cannot create executables" error that there are a lot of threads on (eg http://www.linuxquestions.org/questi...readid=321150). Most seem to have distro specific fixes in them though.

I've tried, clearing LDFLAGS (nothing was set). Looking blankly at /etc/ld.so.conf (seemed fine to me and as you can see in the output the system is finding the 4.1.2 files). I've also tried reinstalling glibc-*.tgz packages.

Looking at the "configure" script the problem arises when the command

Code:

gcc -V </dev/null >&5

is issued.

Running gcc -V requires a number (eg 4.1.2).

I've also tried compiling a "hello world" that I found in another thread but this fails too:

Code:

gcc test.c -o test
/usr/lib/gcc/i486-slackware-linux/4.1.2/../../../../i486-slackware-linux/bin/ld:/usr/lib/gcc/i486-slackware-linux/4.1.2/../../../libc.so: file format not recognized; treating as linker script

collect2: ld returned 1 exit status

Code:

user@hostname:ll `locate libc.so`
lrwxrwxrwx 1 root root  11 2007-04-16 00:34 /lib/libc.so.6 -> libc-2.5.so*

Any thoughts on how to proceed?

Did you cherry pick gcc 4 from current? If yes, try upgrading the rest of your toolchain from current (glibc, binutils, headers) ... and probably the rest of the system too =)

If you self-compiled gcc: did you run the test suites after compilation?

I took gcc-4 and glibc-* and also upgrade binutils, and quite a lot of other stuff from current.

I didn't upgrade the headers, but then I've read elsewhere that this isn't a good idea (I'm running a self-compiled 2.6.16.13 kernel).

I've not gone the whole hog as I don't want to upgrade any Xorg stuff (which usually causes me problems).

I'm an idiot, I hadn't actually updated binutils ... whoops there goes a day I'll never get back again.

I was having the same problem on my Gentoo system. The box was very outdated so I had to manually update gcc from a precompiled package but even after doing that it would not "emerge gcc" to update the system using portage. I finally stumbled upon this after a couple of days that I also needed to update binutils from the latest precompiled package also.

Tips for updating old Gentoo systems.

Code:

cd 

wget http://tinderbox.dev.gentoo.org/default-linux/x86/sys-devel/gcc-4.4.4-r2.tbz2
wget http://tinderbox.dev.gentoo.org/default-linux/x86/sys-devel/binutils-2.20.1-r1.tbz2

cd /

tar xfpj root/gcc-4.4.4-r2.tbz2
tar xfpj root/binutils-2.20.1-r1.tbz2

Then I was able to switch to the new binutils and finally begin updating the system with emerge.

Code:

eselect binutils list
eselect binutils set 2
env-update
source /etc/profile

This is Slackware forum, we do not care about Gentoo... and please do not resurrect a thread that has been dead for three and a half year!
