Custom Makefile Project not compiling .C files

Troubleshooting

Howdy folks,

I’m trying to build a project outside particle source for photon with a custom makefile following the instructions here, but it doesn’t seem to compile any of my application source, and fails when it can’t find the resulting object files.

Here’s my makefile, named build.mk in the APPDIR I pass to make

# location of the QP/C framework (if not provided in an environemnt var.)
ifeq ($(QPC),)
QPC := ../../../../..
endif

# QP port used in this project
QP_PORT_DIR := $(QPC)/ports/arm-cm/qv/gnu

# list of all source directories used by this project
VPATH = \
.. \
../.. \
$(QPC)/source \
$(QP_PORT_DIR) \
$(QPC)/3rd_party/stm32f2 \
$(QPC)/3rd_party/stm32f2/gcc

# list of all include directories needed by this project
INCLUDE_DIRS  += \
	-I../.. \
	-I$(QPC)/include \
	-I$(QPC)/source \
	-I$(QP_PORT_DIR) \
	-I$(QPC)/3rd_party/CMSIS/Include \
	-I$(QPC)/3rd_party/stm32f2

# C source files
MY_SRCS := \
	bsp.c \
	main.c \
   	philo.c \
     table.c \
	system_stm32f2xx.c \
	startup_stm32f2xx.c

QP_SRCS := \
	qep_hsm.c \
	qep_msm.c \
	qf_act.c \
	qf_actq.c \
	qf_defer.c \
	qf_dyn.c \
	qf_mem.c \
	qf_ps.c \
	qf_qact.c \
	qf_qeq.c \
	qf_qmact.c \
	qf_time.c \
	qv.c

CSRC += $(MY_SRCS) $(QP_SRCS)

My understanding of how this works is I just need to append sources/libraries/include_directories to the variables listed in the documentation and the particle build tree will do the rest, but am I missing something? Do I need to specificy a target in this makefile? Error message given below.

File all' does not exist. File…/build/target/user/platform-6-m//libuser.a’ does not exist.

Thanks!
