A few days ago I did an update on my Slackware 10.1 box to a slackware-current version.
This was almost problem-free, except some packages.
But 1 package carried a pretty big problem with it.
GCC.
I upgraded gcc from 3.3.4 to 3.4.6.

After this all, I did want to copmile mysql-5.0.21.
While compiling I get an error.

/usr/lib/../i486-slackware-linux/bin/ld: cannot find -lgcc

It looks like I've got a problem with the library gcc.
So I checked if the library exist.

locate libgcc

As you can see above, libgcc_s.so* exist (in /usr/lib).

I've tried to downgrade to 3.3.6 but this also doesn't solve the problem (the problem still exist).

I've also tried to compile gcc by my own. (3.4.6).
This also doesn't work
While compile I get a different error:



: undefined reference to `__dlopen'



dfcn.h is also in /usr/lib.

So I think gcc is just messed-up.
But now I can't think of a fix about it.

Ahhh! When you switch versions it's important to backup. A minor change 3.3.x isn't a big deal, but when switching 3.3.x to 3.4.x or even better 3.3.x to 4.x you've got to be ready for anything!

I'd probably check to see if it's just a messed up ld.so.conf file, re-run ldconfig and try again. Be sure to updatedb before searching after making the major changes.

If it doesn't work out, you may be able to salvage quite a bit and then just re-install.

Good Luck!

Cool

I did check my ld.so.conf file for configuration.
But that file was good.
In the meantime, I did a re-install of the library.
Everything is solved now.

But I still don't know why it went wrong..
