Hi Rual!

Now I have try to follow strictly the threat

makefile for simple linux device driver (http://www.niosforum.com/forum/index.php?showtopic=2411)

My result is this makefile: 

ifneq ($(KERNELRELEASE),)#  kbuild part of makefile
obj-m := hello.o
else#  Normal Makefile
KERNEL_PLUGIN:= /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0
KERNELDIR := $(KERNEL_PLUGIN)/linux-2.6.x
BUILDDIR := /cygdrive/c/Entwicklung/NIOS/workspace3/Linux_Kernel_full/build
all::
$(MAKE) -C $(KERNELDIR) M=`pwd` O=$(BUILDDIR) modules
endif

Compiler output is:

make -k all

make: nothing to be done for `all&#39;.

And no build output was generated.

Could it be that something is going wrong with pathes.

I have three pathes belonging to the driver I want to build:

1) Path to kernel sources, provided by microtronix. It&#39;s:

/cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0

2) Path to kernel I have compiled. It&#39;s:

/cygdrive/c/Entwicklung/NIOS/workspace3/Linux_Kernel_full

3) Path to driver sources:

/cygdrive/c/Entwicklung/NIOS/workspace3/hello_driver_linux

Bye, Lothar.
