[ovs-discuss] Installation openvswitch

[marwen marwen]

hello

I installed
 kernel-headers-2.6.18-164.15.1.el5.x86_64.rpm
 kernel-devel-2.6.18-164.15.1.el5.x86_64.rpm

and I build successfully the kernel module of Openvswitch with this command
line
./configure --with-l26=/lib/modules/`uname -r`/build/
make
sudo make install

and when I load the module I have this error

dmesg | tail
openvswitch_mod: version magic '2.6.18-164.15.1.el5 SMP mod_unload *gcc-4.3*'
should be '2.6.18-164.15.1.el5 SMP mod_unload *gcc-4.1*'

and when I look for the gcc I have this message

----------------------------------------------------------------------------------------------------
sudo yum install gcc
Package gcc-4.1.2-50.el5.x86_64 already installed and latest version
----------------------------------------------------------------------------------------------------

and when I do

----------------------------------------------------------------------------------------------------
[marwen at node015 ~]$ gcc --version
gcc (GCC) 4.3.4

----------------------------------------------------------------------------------------------------

Thank you for your help
Best Regards
Marwen
