Strange make

[Fustaccio]

Hi. I'm compiling a module for my linux kernel, and I'm working in the eclipse ganymede editor for C/C++.

obj-m += main.o

all:
	make -C /lib/modules/$(shell uname -r)/build SUBDIRS=$(PWD) modules

clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

Giving the command to build all goes fine if I put makefile and other C files on Desktop, but if I try to compile inside Eclipse I get this message:

**** Build of configuration Default for project OMEGA_module ****

make all 
make -C /lib/modules/2.6.28-15-generic/build SUBDIRS=/home/user/Job /Workspace/Module modules
make[1]: entering directory «/usr/src/linux-headers-2.6.28-15-generic»
make[1]: *** No rule to create objective «/Workspace/Module».  
make[1]: exiting directory «/usr/src/linux-headers-2.6.28-15-generic»
make: *** [all] Error 2

Why does this happen? What's the solution for this matter? Thank you all

It looks like it is looking for a directory with a space in the name for SUBDIRS. You need to change the name of the direcory "/home/user/Job " to "/home/user/Job". Note that you will probably need to change some directory settings in your Eclipse environment as well that use the old version of the name (with the space) to use the new one.

Alternatively, you can enclose the PWD variable in the Makefile with double quotes so that the SUBDIRS variable is passed correctly to the subsequent call to make. Note that you would have to do this for all uses of the PWD variable.

The problem was just due to a phantomatic " " in the folder name, which I probably pressed when I created that directory, so make was interpreting that as a real space and searching for a target which was instead a part of a path.

Thank you!

Yeah. My keyboard sometimes thinks it knows better than I do...
