no rule to make target `obj/pins_teensy.o`
I am using Paul Stoffregen's cores instead of Teensyduino, and I edited your Makefile to reflect where the various tools are installed on my system. But I'm getting the following error when I type make:
make: *** No rule to make target obj/pins_teensy.o', needed by bin/blinky.elf'. Stop.
Any suggestions?
That generally means that the makefile can't see pins_teensy.c. I would guess that your TEENSY3X_BASEPATH is not set correctly somehow (although your makefile looks right at first glance, so perhaps $(HOME) isn't expanding correctly or something?). Lines 212-215 of the makefile specify looking in the TEENSY3X_BASEPATH folder for object file dependencies (in this case, pins_teensy.c).
The four $(OBJDIR)/%.o rules specify the places where it will look to try to resolve the files for the targets. When it says that there is "no rule" that means that none of the four rules were able to find a matching C or CPP file, meaning that no pins_teensy.cpp or pins_teensy.c was found in either SRCDIR or TEENSY3X_BASEPATH.
I'm stumped. I just verified that $(HOME) does expand correctly with a test makefile. I do have the files in the TEENSY3X_BASEPATH as I've specified it:
