GNU make stops without error before makefile is finished

Question

Good morning, I am trying to cross-compile for an Atmel AT92SAM using Eclipse with the GNU-Arm toolchain under Windows 7.

My Problem is, that the building process stops after the linker finished, although it should also create a raw binary and print the size. Here is an excerpt from the makefile eclipse created:

# All Target
all: main.exe

# Tool invocations
main.exe: $(OBJS) $(USER_OBJS)
    @echo 'Building target: $@'
    @echo 'Invoking: Cross ARM C Linker'
    arm-none-eabi-gcc -mcpu=arm7tdmi -mthumb -O0 -fsigned-char -ffunction-sections  -g -Xlinker --gc-sections -Wl,-Map,"main.map" --entry=0x00000000 -o "main.exe" $(OBJS) $(USER_OBJS) $(LIBS)
    @echo 'Finished building target: $@'
    @echo ' '

main.bin: main.exe
    @echo 'Invoking: Cross ARM GNU Create Flash Image'
    arm-none-eabi-objcopy -O binary "main.exe"  "main.bin"
    @echo 'Finished building: $@'
    @echo ' '

main.siz: main.exe
    @echo 'Invoking: Cross ARM GNU Print Size'
    arm-none-eabi-size --format=berkeley "main.exe"
    @echo 'Finished building: $@'
    @echo ' '

But the last two commands are not performed and no .bin is created. The Commandline Output is

...

08:31:22 Build Finished (took 10s.91ms)

As you see, the objcopy and size commands are not called. Any Ideas?

Are you just invoking "make" or "make all"? If so, it's doing exactly what your "all" target is telling it to... — Notlikethat, Nov 04 '16 at 08:25
You are right.. Obviously the eclipse options are not set right. — DrJohn, Nov 04 '16 at 09:48

You may directly add the size inside main.exe recipe as main.siz is not a real output file (which should be .PHONY):

all: main.bin

main.exe: $(OBJS) $(USER_OBJS)
    @echo 'Building target: $@'
    @echo 'Invoking: Cross ARM C Linker'
    arm-none-eabi-gcc -mcpu=arm7tdmi -mthumb -O0 -fsigned-char -ffunction-sections  -g -Xlinker --gc-sections -Wl,-Map,"main.map" --entry=0x00000000 -o "$@" $(OBJS) $(USER_OBJS) $(LIBS)
    arm-none-eabi-size --format=berkeley "$@"
    @echo 'Finished building target: $@'

main.bin: main.exe
    @echo 'Invoking: Cross ARM GNU Create Flash Image'
    arm-none-eabi-objcopy -O binary "$<" "$@"
    @echo 'Finished building: $@'

GNU make stops without error before makefile is finished
