Debian users, In
http://git.kernel.org/?p=linux/kernel/git/linville/wireless-dev.git;a= summary Vivek described a makefile containing this text. obj-m := hello.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules shell is not a command in the Etch here. So what is "shell uname -r" and "shell pwd"? Why not just $(uname -r) and $(pwd)? Thanks, ... Peter E.
