I've been playing with the current version of the Gen7 branch of Teacup and it seems like the new Makefile are not working on Ubuntu 12.04 properly: when having build targets in the BUILDDIR (e.g. build/teacup.elf or build/clock.o) make complains that the needed rule is missing. For example:
make -f Makefile-AVR all
rm -f build/depend
mkdir -p build
avr-gcc -DF_CPU=16000000L -mmcu=atmega644p -g -Wall -Wstrict-prototypes -std=gnu99 -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -Winline -fno-move-loop-invariants -fno-tree-scev-cprop -Os -ffunction-sections -finline-functions-called-once -mcall-prologues -save-temps=obj -MM analog.c clock.c copier.c crc.c dda.c dda_maths.c dda_queue.c debug.c delay.c gcode_parse.c gcode_process.c graycode.c heater.c home.c intercom.c mendel.c pinio.c sd.c serial.c sermsg.c sersendf.c temp.c timer.c usb_serial.c watchdog.c > build/depend
make: *** No rule to make target `teacup.hex', needed by `all'. Stop
Building an object file directly:
make -f Makefile-AVR build/clock.o
make: *** No rule to make target `build/clock.o'. Stop.
Now I set BUILDDIR to an empty string and the depend file to simply 'depend':
make -f Makefile-AVR clock.o
#rm -f depend
#mkdir -p
avr-gcc -DF_CPU=16000000L -mmcu=atmega644p -g -Wall -Wstrict-prototypes -std=gnu99 -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -Winline -fno-move-loop-invariants -fno-tree-scev-cprop -Os -ffunction-sections -finline-functions-called-once -mcall-prologues -save-temps=obj -MM analog.c clock.c copier.c crc.c dda.c dda_maths.c dda_queue.c debug.c delay.c gcode_parse.c gcode_process.c graycode.c heater.c home.c intercom.c mendel.c pinio.c sd.c serial.c sermsg.c sersendf.c temp.c timer.c usb_serial.c watchdog.c > depend
avr-gcc -DF_CPU=16000000L -mmcu=atmega644p -g -Wall -Wstrict-prototypes -std=gnu99 -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -Winline -fno-move-loop-invariants -fno-tree-scev-cprop -Os -ffunction-sections -finline-functions-called-once -mcall-prologues -save-temps=obj -c -o clock.o clock.c
Alternatively I link the source file to the 'build' directory: clock.c -> build/clock.c:
make -f Makefile-AVR build/clock.o
avr-gcc -DF_CPU=16000000L -mmcu=atmega644p -g -Wall -Wstrict-prototypes -std=gnu99 -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -Winline -fno-move-loop-invariants -fno-tree-scev-cprop -Os -ffunction-sections -finline-functions-called-once -mcall-prologues -save-temps=obj -c -o build/clock.o build/clock.c
build/clock.c:7:19: fatal error: pinio.h: No such file or directory
compilation terminated.
make: *** [build/clock.o] Error 1
Note that it failed as the other source files are missing but at least Make is not complaining about missing rules.
It seems that having the source file in another folder from the target object file is somehow confusing Make...
So does this split-makefile work for other people besides me or is it just broken at the moment?
Edit: I added a rule before the include in 'Makefile-common':
build/clock.o: clock.c
echo "Works!"
This works as expected; it seems to be an issue with the wildcard target matching.
