Hi again :-)

Try following build script and Makefile:

---------- build.sh ----------

#!/bin/bash

# Set Variables
KERNEL_CC=`rtai-config --cc`
LINUX_DIR=`rtai-config --linux-dir`
MODULE_DIR=`rtai-config --module-dir`
TARGETS=""

if [ "x$1" != "x" ]
then
    TARGETS="$1"
fi

make -C "$LINUX_DIR" M="$PWD" CC="$KERNEL_CC" V="$V" $TARGETS



---------- Makefile ----------

EXTRA_CFLAGS += $(shell rtai-config --module-cflags) 

obj-m  += rtai_pulsmod.o


---------- End of Files ----------

Greetings,

Malte
