Compiling _stage.mpy

Hello,

I was very happy to see the native modules being added to release 1.12, as described at http://docs.micropython.org/en/latest/d ... atmod.html so I decided to go and try to compile my "stage" game library this way, because a lot of people wanting to use it are unable to compile their own firmware. I actually need to compile only a very small "_stage" helper module, that contains two classes for tile layers, and a simple function for rendering them and sending over SPI to the display. According to the documentation, it should be very simple.

So I started with my mod_stage.c (https://github.com/python-ugame/micropy ... od_stage.c) and replaced the module dict definition with the mpy_init function, as in the examples. I got _stage.c file: https://github.com/python-ugame/micropy ... y/_stage.c

So far so good. Next I created a simple Makefile based on the examples:

Code: Select all

MPY_DIR = ../../../micropython/micropython
ARCH = xtensa
MOD = _stage
SRC = _stage.c

include $(MPY_DIR)/py/dynruntime.mk
Unfortunately, running this results in a missing include "mphalport.h". A quick search in the MicroPython's code revealed, that there is no mphalport.h for the ESP8266, so I decided to try compiling for the ESP32 first. I added the include path to CFLAGS:

Code: Select all

CFLAGS += -I$(MPY_DIR)/ports/esp32/
this time it failed with some missing includes from esp-idf. I kept adding include directories, until I got to:

Code: Select all

MPY_DIR = ../../../micropython/micropython
ARCH = xtensawin
MOD = _stage
SRC = _stage.c

CFLAGS += \
	-I$(MPY_DIR)/ports/esp32/ \
	-I$(MPY_DIR)/ports/esp32/build \
	-I../../../micropython/esp-idf/components/freertos/include \
	-I../../../micropython/esp-idf/components/esp32/include \
	-I../../../micropython/esp-idf/components/driver/include \
	-I../../../micropython/esp-idf/components/soc/include \
	-I../../../micropython/esp-idf/components/soc/esp32/include \
	-I../../../micropython/esp-idf/components/heap/include \


include $(MPY_DIR)/py/dynruntime.mk
This time there is no include error, but instead I get several screenfuls of errors:

Code: Select all

I figured that one out, you can't use any _ROM_ functions, so the creation of classes is a bit more involved and has to be done in the init funcvtion. The framebuf module is a good example of that.

However, now I'm getting:

Code: Select all

Traceback (most recent call last):
  File "../../../micropython/micropython/tools/mpy_ld.py", line 964, in <module>
    main()

The fight continues. After changing the "if s.data_size == 0:" line in mpy_ld.py to "if getattr(s, 'data_size', 0) == 0:" I get a new error. This time it can't find the symbol mp_obj_get_array, which is used in my code. What to do? The function is defined in py/obj.c, so I tried adding it to SRC. Unfortunately that gives me:

Code: Select all

$ make

which seems to be completely crazy?

Re: Compiling _stage.mpy

I gave it another go. This time I installed the latest version of python3-elftools, which "fixed" the AttributeError. However, I still get the symbol not found error for "mp_obj_get_array", which is, come to think about it, very suspicious, because other symbols from the py/obj.c are found without problems. Is there maybe some list of symbols somewhere that the dynamically loaded modules can use that is missing mp_obj_get_array in it perhaps?

For anyone struggling with a similar problem, here is a missing piece of documentation: https://github.com/tve/micropython/comm ... dd114d4fae
