Description Martti Leppänen 2006-07-05 14:47:28 UTC 
Description of problem:

In the (now) newest kernel 2.6.9-34.0.1.ELsmp the compile time gcc version is:

> dmesg | grep -i gcc
Linux version 2.6.9-34.0.1.ELsmp (bhcompile.redhat.com) (gcc 
version 3.4.6 20060404 (Red Hat 3.4.6-2)) #1 SMP Wed May 17 17:05:24 EDT 2006

And the installed newest gcc is:

> gcc -v
gcc version 3.4.5 20051201 (Red Hat 3.4.5-2)

Thus compiling modules for the kernel becomes impossible. The gcc-3.4.6-2 is 
not available as an rpm as far as I can find.

Version-Release number of selected component (if applicable):

2.6.9-34.0.1.ELsmp (bhcompile.redhat.com) (gcc version 3.4.6 
20060404 (Red Hat 3.4.6-2))

How reproducible:

By installing the normal install of RH EL4 AS and updating it with up2date

Steps to Reproduce:
1. Install RH EL4 AS
2. Update with up2date

The newer version of gcc should not affect the the compatability of kernel
modules...if you can point to a specific problem please re-open.

Fujitsu Siemns server management kernel modules srcrpm

This RPM contains sources for 3 modules for the 2.6.9 kernel. They compile fine
in Redhat EL4 AS, but when I tried to load them, I get an error:
insmod: error inserting '/lib/modules/2.6.9-34.0.1.ELsmp/srvmagt/copa.ko': -1
Invalid module format

I got the same error when trying to compile bmcsensors-26
(http://bmcsensors-26.sourceforge.net/) module to the kernel.

I suspected this might come from the version differences in gcc, but apparently
it is somewhere else?
