[ASK] Install kernel-source and gcc for driver installation

[froggyugly]

How to install kernel-source and gcc?
Because if i want to compile module for installing Linux* Base Driver i've to
install them first.

And then this is what happen when i tried to compile:

[root@localhost src]# make
make -C /lib/modules/2.6.18-194.el5/build SUBDIRS=/root/AR1FAmily-linux-v1.0.1.13/src modules
make[1]: Entering directory `/usr/src/kernels/2.6.18-194.el5-x86_64'

I don't get what's going on,so maybe it's happened because i haven't install
the kernel-source and gcc.

I hope that there's anyone who can help me

I would guess that it is a problem with the code, seeing as how it ran make, got to a line with CC, and tried to compile but threw an error /root/AR1FAmily-linux-v1.0.1.13/src/kcompat.h:1575: error: redefinition of ‘struct napi_struct’

can you show source code of what you are trying to compile?

in any case, you need to tell us your distro and version so we can tell you how to install GCC and kernel headers if necessary

Actually, to build drivers you should not need the full kernel sources unless you have some specific dependencies on the physical code implementation. Normally, all you need is the kernel development package (headers) to build your kernel module(s). Also, gcc is probably already installed on your system, and unless you want to use a non-supported gcc version (like the latest 4.5.1) you should be good to go. Just try to execute the command gcc --version and see what you get.

i'm using centos 5.5..
the source code is source code for the Atheros ethernet driver.
now i've changed the Atheros ethernet card with Intel ethernet card.
and i still got the problem with installing the driver, because after i read the README, it can be installed if the centos has already the kernel-source and kgcc..

but this case is different when i got few days ago..
when i still use the Atheros ethernet card, in network configuration adepter column, it didn't show the Atheros, but with Intel it did.

the next problem is how do i install the kernel-source and kgcc?
while the centos cannot connect to the internet.

thank you to both of you so much for helping me.
now i'll try next solution.
