Hi ashish ,


they are the object files which were linked into the kernel module
file(.ko), you need not worry about them , they should actually be
gone if you run 'make clean' 

also for more info refer to LDD 3rd edition (Linux Device Drivers) ,
it is all explained there , .. .you should be able to find free
versions of the book in PDF format on the web , ..


Thanks
Satish

 Hi Santosh,

 The problem was in the make file. I had put pcnet32.c instead of .o. The
 module has now been compiled. Now I got 4 files

 pcnet32.ko - I placed in /lib/modules/2.6.25.14/kernel/drivers/net

 What should I do with the rest. What are these for? I found similar file
 types in the /usr/src/linux-2.6.25.14/(different folders)

 pcnet32.mod.c
 pcnet32.mod.o
 pcnet32.o

 Hi,

 I dont know why this is not working for me. I was able to compile the
 hello
 world module without errors.

 I got the below error:

 make -C /lib/modules/2.6.25.14/build M=/root modules
 make[1]: Entering directory '/usr/src/linux-2.6.25.14'
 scripts/Makefile.build:217: target '/root/pcnet32.c' doesn't match the

 Building modules, stage 2.
 MODPOST 0 modules
 make[1]: leaving directory  '/usr/src/linux-2.6.25.14'
 I got the pcnet32.c file from
 /usr/src/linux-2.6.25.14/drivers/net/pcnet32.c. 2.6.25.14 is a compiled
 kernel.

 Why is it that pcnet32.c did not get compiled when the kernel was
 compiled?
 or when the modules were compiled?

 Regards,
 Ashish


 I had a wrong idea, the actual error is with the makefile. Somewhere
 regexps are used, which could not match the specified pattern. Thats the
 problem.

 Thanks

[Ilugc] How to compile module

2008-12-11 Thread Ashish Verma 
Hi,

I have a pcnet32.c file. I want to make a module out of it. What should I
do. The below link requires me to make a make file. I don't know how to do
that. Please advise.

Hi Ashish,
Do you have a custom compiled kernel? If so then, it is not necessary to 
download headers. If not, you have to download the headers and write a 
makefile. The makefile is very simple.


obj-m += yourfile.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


Then
make modulename

There is no specific directory to place your source, just compeile it 
and later you can insert.


Thanks,
Santosh
