Error: "make: *** No rule to make target `folder'. Stop. "

[shri19]

hello all,

i am a fedora10 user and i am getting this no rule to make target error while compiling a simple hello world program.

here is the output when i try to compile the program.

[root@localhost untitled folder]# make -C /lib/modules/2.6.27.21-170.2.56.fc10.i686/build/ M=`pwd` modules
make: Entering directory `/usr/src/kernels/2.6.27.21-170.2.56.fc10.i686'
make: *** No rule to make target `folder'. Stop.
make: Leaving directory `/usr/src/kernels/2.6.27.21-170.2.56.fc10.i686'

I googled this topic a lot but still the problems remains and i am totally stuck with this for the last few days. Please help me out.

Is there an appropriate makefile?

[shri19]

nope. i haven't used any makefile for this. I also tried compiling with a Makefile. Again i came across the same thing but this time there was an additional Error 2. here's the output.

[root@localhost untitled folder]# make
'make -C /lib/modules/2.6.27.21-170.2.56.fc10.i686/build M=/root/untitled folder modules
make[1]: Entering directory `/usr/src/kernels/2.6.27.21-170.2.56.fc10.i686'
make[1]: *** No rule to make target `folder'. Stop.
make[1]: Leaving directory `/usr/src/kernels/2.6.27.21-170.2.56.fc10.i686'
make: *** [all] Error 2

the makefile that i used is as follows.

obj-m += hello-1.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

I'm no expert on such things, but that doesn't look like a valid makefile to me. Instead of listing the commands needed to make the program, you're just calling make recursively. You might want to check with this tutorial to see what a proper makefile looks like: http://www.opussoftware.com/tutorial/TutMakefile.htm

The prompt shows that you have a space in your directory name. Don't do that, it breaks a lot of programs. Additionally, don't build software as root. Build it as a regular user and switch to root only for installation.

It's the standard kind of makefile for building kernel modules, there's nothing wrong with it. See: http://tldp.org/LDP/lkmpg/2.6/html/x181.html
