Recompile the Library of the Linux Kernel

Recompile the Library of the Linux Kernel

[LI LEI]

Hello, everyone,

I am a beginner to learn about the linux kernel. I met the following
problem today:

I created a C file called "drv_event.c", and put it into the location
"/lib", since I want to link it to the library of the kernel, i.e., *lib.a*.
I also put the header file "drv_event.h" into the directory
"/include/linux". I recompile the directory "/lib", and my own object
"drv_event.o" was successfully linked into the *lib.a*.

However, I called one of the functions defined in the "drv_event.c" in my
driver, and I compiled this driver, at the link time, I got the warning
which shows that the function called is undefined.

It seems although I do recompile the lib.a successfully, but I did not put
the new one into the right place. I tried "make install lib" and also "make
install" in the kernel source. However, I still got the same warning at the
link time.

So does someone can help me to get rid of this problem?

Thanks so much.

Best,

Li

Would you please show us the warn message?
does your driver made in module format or build-in?
