Compilation error in Slackware 14.0
 

Recently installed Slackware 14.0 and can't be more happy with it. Only problem is i haven't been able to compile any app. Tried with dzen2 and asclock. Both compilations failing with the same error:

gcc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found

I've tried using:

-fno-lto -fno-use-linker-plugin

with the same result. I've checked that the LIBRARY_PATH variable points to the right dir and that the requested file is present:

aaro ~ $ echo $LIBRARY_PATH
/usr/libexec/gcc/i486-slackware-linux/4.7.1

aaro ~ $ locate liblto_plugin.so
/usr/lib/liblto_plugin.so
/usr/libexec/gcc/i486-slackware-linux/4.7.1/liblto_plugin.so.0.0.0
/usr/libexec/gcc/i486-slackware-linux/4.7.1/liblto_plugin.so
/usr/libexec/gcc/i486-slackware-linux/4.7.1/liblto_plugin.so.0

aaro ~ $ uname -a
Linux satellite 3.2.29-smp #1 SMP Mon Sep 17 13:02:10 CDT 2012 i686 Intel(R) Core(TM) i5 CPU M 450 @ 2.40GHz GenuineIntel GNU/Linux

Also tried compiling dzen2 with slackbuilds script with same result. So, right now i'm clueless. I'm using Slackware 14.0 i686 (full install). It's running on my 64 bits processor powered laptop (core i5). Any help appreciated. Thanks in advance.

Well I don't think you should have a copy of it in /usr/lib as it isn't in the gcc package.

Also what are the file sizes for those files, as in are they actually a file or are they empty.

The one in /usr/lib was my first try for a workaround, it was not originally there.
Here the files and sizes:

Well the file size matches the package so it should be ok.

Apart from installing the system what have you done with it before now (questions below :- )

Are these the first programs you have tried to compile?
Have you installed other 3rd party packages?
Did you do a full install or did you skip packages?

Only additional thing i made was add 3rd party repositories and installing some packages from there. I installed slacky.eu and salix repos and used slapt-get to install some packages. Even though i was very careful assigning priorities with official slackware repos with the highest, slacky.eu second and salix 3rd. It's the only thing i can think where something could go wrong. And if nobody else is getting this same error so i can suppose that it's my installation the problem. Many thanks for the help anyway :)

I have no problem here building that packages.Slackware64 current
