I got them to link up without error using the make file at the top of this page. anyone had experience with that?? i'd love to hear about it. mallyj on "Makefile help" http://forums.leaflabs.com/topic.php?id=74370#post-105514 Tue, 16 Sep 2014 15:21:18 +0000 mallyj 105514@http://forums.leaflabs.com/ again, thank you, everything is almost running smoothly. But I keep getting the error: make[1]: *** No rule to make target <code>build//Users/malcolm/goodjob/FFTCM3.o', needed by</code>build/maple.elf'. Stop. make: *** [sketch] Error 2 what could that mean? any suggestions? mallyj on "Makefile help" http://forums.leaflabs.com/topic.php?id=74370#post-105512 Mon, 15 Sep 2014 06:59:55 +0000 mallyj 105512@http://forums.leaflabs.com/ Amazing!

In case you have missed it.

I've have learned a wonderful amount l since I started but feel at the moment that I am pretty hung up. My immediate goals right now are: -Link an object file from an asm source with an object file from a cpp source with out error -Upload to maple I've been making very small steps toward the first item's completion but am all out of ideas. my calls in main.cpp for delay() and SerialUSB.println() produce errors of the kind main.cpp: In function 'void loop()': main.cpp:27: error: 'SerialUSB' was not declared in this scope So i assume the i am not properly linking against libmaple.a as its been said i should do. or that i haven't properly modified the include path. maybe i'm misunderstanding what is meant by " your include path should contain the directories ~/libmaple/libmaple and ~/libmaple/wirish/". Someone please set me straight. I should note that when i comment out the calls for SerialUSB.println() and delay() make does produce all the target files. Whether or not they are produced correctly, I don't know. Also, the actual program i will finally upload to Maple will be alot more dependent on libmaple than just using SerialUSB.println() and delay(). I'll be using the register map for ADC and DMA stuff. so i cant just replace them with a more standard implementation. this is the Makefile: ############################################################### OBJ = main.o asm.o INC = -I~/libmaple/libmaple -I~/libmaple/wirish -I~/libmaple/wirish/wirish.h CC = ~/libmaple/arm/bin/arm-none-eabi-gcc program : $(OBJ) $(CC) -Wall -L ~/libmaple/build/ -l maple \ -o program.elf main.o : main.cpp $(CC) -Wall $(INC) -c main.cpp asm.o : asm.s $(CC) -Wall $(INC) -x assembler-with-cpp asm.s ############################################################### Yes, it's true, i don't know what i'm doing. but I am desperately trying to figure that out. Any guidance is much appreciated.
