Hi everyone ... I (obviously) have a problem after upgrading to a new kernel.
I'm running Slack 9.1 amd upgraded from the standart 2.4.22 to 2.6.8.1

there were no problems at all configuring and compiling the new kernel ... but now some of my libraries dont seem to work anymore ... for example my nvidia kernel module (yes I recompiled it for the new kernel) ... the other one not working is libGL

ldconfig gives me the follwing hints:

/usr/lib/libGL.so.1 is not an ELF file - it has the wrong magic bytes at the start.

ldconfig: /usr/lib/libGL.so.1.0.5336 is not an ELF file - it has the wrong magic bytes at the start.

ldconfig: /usr/lib/libGL.so is not an ELF file - it has the wrong magic bytes at the start.

ldconfig: /usr/lib/libGLcore.so.1 is not an ELF file (it's always the same error)

ldconfig: /usr/lib/libGLcore.so.1.0.5336 is not an ELF file

ldconfig: /usr/X11R6/lib/libXvMCNVIDIA.so.1.0.5336 is not an ELF file

ldconfig: /usr/X11R6/lib/libXvMCNVIDIA_dynamic.so.1 is not an ELF file

ldconfig: /usr/X11R6/lib/libXvMCNVIDIA.so.1 is not an ELF file

ldconfig: /usr/X11R6/lib/libXvMCNVIDIA.so is not an ELF file

can someone tell me what's wrong and why some things aren't working ? and most of all .. what to do about it

this might be completely wrong, but do you have a.out support in your new kernel image as well as ELF?

yes I do ... that's the point I dont get ... it should work :S

ok ... I found out some more information ...
1. it's not just a problem in 2.6.8.1 anymore ... I also get the same error when I boot my backup kernel (2.4.22)

2. at compile and at boot time I get the following messages:

agpgart: version magic '2.6.8.1 K7 4KSTACKS gcc-3.2' should be '2.6.8.1 SMP preempt K7 4KSTACKS gcc-3.2'

ide_scsi: version magic '2.6.8.1 K7 4KSTACKS gcc-3.2' should be '2.6.8.1 SMP preempt K7 4KSTACKS gcc-3.2'

what does that mean ? I deactivated 4k stacks by now and I still get that error.... by the way .. this is just a short list of invalid modules ... there are far more.

I really hope anyone can help!

right so you compiled this kernel from scratch right? by default SMP (multiple cpu support) is normally on, for some odd reason, which i'm assuming is what the kernel configuration was for the older kernel. turning it back on will not have a negative effect, it'll just be ignored. you'd also want to enable preemptive scheduling too.. which i believe is on the same config page.

as a disclaimer i've not seen errors like that before, it just looks implicit that making those changes should make the magic numbers the same.

Oh, maybe i'm reading it a little wrong, and the new kernel's magic is on the left, not the right.... so you might want to disable it instead of enabling it!

ok .. thanks .. I'll just check what I did before and do the opposite

ok ... I've just enabled SMP and recompiled the kernel ... and most things work fine now ... I still get some of those errors concerning libGL ... but I haven't noticed any programm that's not working right.
so thanks for the help .... I think I can figure out the rest myself

cool, suprised i got that to be honest...
