U can compile u'r code by Makefile.
create a file name called "Makefile" (should be) in u'r code directory.
edit it as follows,

obj-m += hello.o //(u'r code filename.o)
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

No need to compile the Makefile. then enter the command "make" in the same directory. it will create .ko file, if u r using 2.6 kernel.otherwise, .o file. Once u compiled u'r code by "make", if u want to compiled it again, enter "make clean", then enter "make".

try it.

Hi,

I trying to compile my kernel for Broadcom Netxterme 5782 with Broadcom Tigon3 (tg3) which is with linux but not compiled. so while compiling and making module by command:

make modules

It giving an error like:

make[2]:*** [tg3.o] Error1
make[2]: Leaving directory `/usr/src/Linux-2.4.20-8/drivers/net`
make[1]:*** [_modsubdir.net] Error 2
make[1]: Leaving directory `/usr/src/Linux-2.4.20-8/drivers`
make[1]:*** [_mod_drivers] Error 2


I don't understand this error message and if you have any otherway to activate Broadcom NIC please do write that also.

Thanks in advance.

Best,
Neepa.

Do you have it enabled in your kernel config?
If yes, then from your top-level kernel source directory, just do make modules
If not, then configure your kernel as given in the README and then compile the modules.

Thanks asprakash its working, one more problem

i want to compile one file which is composed of two different files
i used the command but error of something missing is coming, could u plz suggest the possible reason

ld -m elf_i386 -r -o file.o file1.o file2.o

Thanks in advance

You ate the other parameter options? (just kidding)

Use a proper Makefile to build drivers. Check in your kernel .config file if you have CONFIG_MODVERSIONS set.

Check my device driver examples for a simple driver and Makefile examples:

I compiled the hello_world module in 2.4.20 Kernel version. It was succesfull. I then loaded the module using insmod command. It was succesful ( lsmod command showed my module name ) But I got no output . I used the printk("hello world") function and used the module_init() function in the hello world program.

Can anyone tell me what's the problem ??

Dear friend!
Please post your threads separately!
U should compile you module program from console only; Not from X window.Printk doesn't print anything on the screen, when you are using X window.so use "dmesg" to show the message; If you use console you can see your message without use of dmesg command.
