More advanced makefile - c

Question

I am currently creating (well at least I'm trying) to create a makefile for a software project.
Since I never used make before I quickly ran into problems.
The software project contains of many subfolders and subsubfolders containing source and header files.
Those files should be collected recursivly and after that beeing build and linked using cross arm toolchain.
The current makefile looks as following:
RM := rm -rf
# Every subdirectory with source files must be described here
DIR := \
D:/foxmake/
SUBDIRS := \
src/test \
src/test/usb_cdc_lolevel \
src/os \
src/os/FreeRTOS/Source \
src/os/FreeRTOS/Source/portable/MemMang \

using eclipse to execute this makefile gives me this error:

Anyone knows why my makefile fails?
What's wrong with the rule "%.o: %.c ,$(C_SRCS)"?
