RUN make command means what

[iinfi]

i have a USB to ethernet device which i want to use in linux.
i downloaded the driver files from the net for the same but am unable to understand the instructions.
the instructions in the readme go as follows.

DAVICOM Semiconductor Inc. 11/24/2006

A. Compiler command:

Run make command <<< how do i run this?

B. The following steps teach you how to activate NIC:

B-1: A simple and temporary method

1. Used the upper compiler command to compile dm9601.c

2. Insert DM9601 module into kernel
"insmod dm9601.ko" ;;Auto Detection Mode (Suggest)
"insmod dm9601.ko mode=0" ;;Force 10M Half Duplex
"insmod dm9601.ko mode=1" ;;Force 100M Half Duplex
"insmod dm9601.ko mode=4" ;;Force 10M Full Duplex
"insmod dm9601.ko mode=5" ;;Force 100M Full Duplex

NOTE: You can type "man insmod" to see more description.

3. Config a DM9601 network interface
"ifconfig eth0 172.22.3.18"
^^^^^^^^^^^ Your IP address

NOTE: 1. You can type "man ifconfig" to see more description.
2. If eth0 has been used, you should use eth1 instead.

4. Activate the IP routing table. For some distributions, it is not
necessary. You can type "route" to check.

"route add default netmask 255.255.255.0 eth0"

NOTE: 1. You can type "man route" to see more description.
2. If eth0 has been used, you should use eth1 instead.

5. Well done. Your DM9601 adapter actived now.

Note. This is a temporary method. After you reboot the system, you
will lost the setting.


B-2: For Redhat, You can use the following to Activate NIC

1. login your system used the superuser.
2. copy dm9601.ko into /lib/modules/2.6.x/kernel/drivers/net/
3. add the new line with "alias eth0 dm9601" in "/etc/module.conf".
4. execute "netconfig -d eth0".
5. Fill your IP address, netmask and gateway
6. press <ok> to confirm and exit this setting
7 reboot

Note. If eth0 has been used, you should use eth1 instead.

#endif	/* _DEV */

do the above code make any sense ??
atleast i dont understand the instructions.
1st step RUN make command!! how do i do this???

[Faun]

Run these commands one by one !

./configure

make

sudo make install

if u are using other linux(in which sudo is not installed) then in third step first

su -

and then

make install

[iinfi]

thanks ... will try this tomorrow n post the results.
added:
i m sorry wat u told me doesnt work
i m logging in as root user only. the 3 files r in a directory in /root location
now from where sud i run this command??
i did the following ... greek n latin to me.

[root@localhost dm9601-2.6]# pwd
/root/dm9601-2.6
[root@localhost dm9601-2.6]# ./configure
bash: ./configure: No such file or directory

[Hitboxx]

Looking at that read me, I don't think it requires ./configure.

Just do make., (from inside the same directory)

[root@localhost dm9601-2.6]#make

If it says make not found, you have to install the make package from the repo, depending on your distro. What distro are you using by the way?

[iinfi]

i didnt understand the read me.
will try wat u said....
added:
btw wat does ./configure do??

this is the error i get if i run make.... i m running RHCE 5

[root@linux dm9601-2.6]# make
make -C /lib/modules/2.6.18-53.el5/build M=/root/dm9601-2.6 LDDINCDIR=/root/dm9601-2.6/../include modules
make[1]: Entering directory `/lib/modules/2.6.18-53.el5/build'
make[1]: *** No rule to make target `modules'.  Stop.
make[1]: Leaving directory `/lib/modules/2.6.18-53.el5/build'
make: *** [default] Error 2

where is the trouble??

1) Looks like you are missing kernel sources. How did you acquire RHEL5? Bought it, got it from a friend, Certification course? If you bought it, then you should contact Redhat support because you are entitled to it and they will provide the necessary solution(s). Same goes for Certification.

2) If you are using RHEL 5, then why are you compiling it? Start from Appendix B-2.

./configure - ./configure is a bash script that generates a Makefile after analyzing your system. The configure script is built by the autoconf program given a configure.ac or configure.in template file. A Makefile is like saying setup.exe on Windows, ./configure readies the app in question to be installed.

hi ... i got RHEL 5 from my training center. yea certification.

the second line in b-2 says
2. copy dm9601.ko into /lib/modules/2.6.x/kernel/drivers/net/

i dont have the .ko file.
i only have these files.
Makefile
dm9601.c
dm9601.h

sry i m not too familiar with this stuff.

[Hitboxx]

Try locate dm9601 in the terminal,

For eg., I have it here

[hitboxx@Mothership ~]$ locate dm9601
/lib/modules/2.6.27.4-68.fc10.x86_64/kernel/drivers/net/usb/dm9601.ko
/lib/modules/2.6.27.5-109.fc10.x86_64/kernel/drivers/net/usb/dm9601.ko
/lib/modules/2.6.27.5-117.fc10.x86_64/kernel/drivers/net/usb/dm9601.ko

[iinfi]

i m afraid there arent any .ko files in my system with that name...

[mediator]

Here!
1. Edit your "dm9601.c" and change '#include <linux/config.h>' to '#include <linux/configfs.h>'
2. If necessary change the 'CFLAGS' TO 'EXTRA_CFLAGS' in the Makefile.
3. and then try with 'make'!

I suggest you use fedora if you are doing RHCE and install Redhat on virtual machine to pass the exam.
