to install the driver for a TI acx111 wireless pci card, i have to compile the
kernel. my kernel is 2.6.7-1, fc2. i installed the rpm packages of kernel-source and kernel-headers.
when i "make modules" under /usr/src/linux/, i got this error message:
scripts/Makefile.build:13: usr/Makefile: No such file or directory
make[1]: *** No rule to make target `usr/Makefile'. Stop.
make: *** [usr] Error 2

here is the Makefile.build:
src := $(obj)


.PHONY: __build
__build:

# Read .config if it exist, otherwise ignore
-include .config


include $(obj)/Makefile <-line 13 here


include scripts/Makefile.lib

there is not a directory called usr under /usr/src/linux at all.
do i miss anything? i mean, do i should have more packages installed b4 i can compile the kernel?
i have been trying to make the stupid TI based card to work for several days and now the system can detect it but just cannot get it work. anyone has a clue for that also?

thanks for your advice!

in FC2 you have a software install program (system-config-«something»)

use this program to install all the packages you need to compile the kernel (kernel hacking section, i think)

i hope this will help you,

You sure you need to compile a whole new kernel for that? Most drivers come as a separate package that is installed by itself, then loaded later.

i tried system-config-network but i think this only configures the network, not building the module.
after system-config-network, the network is configured as:
axm 111 54mbps wireless eth0 status ok
acx_pci wlan0 configured
here is what i have in /etc/modprobe.conf

alias eth0 tulip
options acx_pci firmware_dir=/root/acx100-0.2.0pre8_plus_fixes_18/firmware
alias wlan0 acx_pci

when i tried to activate the wireless connection, i got:
Command failed: /sbin/modprobe acx_pci
FATAL: Error inserting acx_pci (/lib/modules/2.6.7-1.478/net/acx_pci.ko): Invalid module format

according to the acx100 howto, this is due to different gcc versions used to compile acx_pci.o and kernel
so i have to compile the kernel first

any idea?

when i try to: insmod firmware_dir="the directory having acx_pci.o", i got:
acx_pci.o invalid module format
according to the acx100 howto, this is due to the different versions of gcc used
to compile the acx driver and the kernel.
so what should i do? isn't it true that i have to compile the kernel as well?

Did the download contain file *.o, or did you compile the driver?

If you compiled the driver, you probably have the wrong kernel sources installed.
Delete the current module file, then go back to the source for the module. Run it again, and tell me if it says anything about kernel sources.

I compiled the driver. i just "make" under the source of acx100.
and under /usr/src/linux, "make menuconfig;make dep;make clean;make modules"
i downloaded the source tree and no major errors while "make modules".

now if i type: insmod acx_pci.o firmware_dir="the directory containg acx_pci.o",
still got the invalid module format message.
did i do anything wrong?

another thing is when starting linux, it shows the card is identified as: TI acx111 54M pci
but it is configured as eth0 in /etc/modconfig, why? should not it be configured as
wlan0 since i have "alias wlan0 acx_pci" at /etc/modprobe.
there is only one network card now, i take the ethernet card out.
