Lv_micropython build fails on mac OS

I tried to build lv_micropython on mac OS Monterey using unix port but it fails:

Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

I was expecting it to work since official micropython builds without a problem. Does it mean that lv_micropython wont compile on mac os?

Hi @wiklod !

lv_micropython is aligned to latest Micropython release, which is v1.17.
When you are saying that “official micropython builds without a problem” - did you check v1.17 official release, or just latest Micropython from git?

I’m not aware of any reason why lv_micropython won’t compile on mac os, if the official version does.
The offending “section” argument is created by mpy-tool.py, which is almost the same between lv_micropython and official Micropython v1.17.

Thank you for your reply and I am sorry for the delayed answer.

I was indeed building latest micropython from git, but I checked with the official release v1.17 moment ago and it also builds. The problem occurs only with lv_micropython. I was building MicroPython according to this official(?) guide.

Looks like Mac has some issue with freezing code that is specified as native.

Try to remove “imagetools.py” from manifest.py so it won’t be frozen.

github.com

lvgl/lv_micropython/blob/master/ports/unix/variants/manifest.py

freeze_as_mpy('$(MPY_DIR)/tools', 'upip.py')
freeze_as_mpy('$(MPY_DIR)/tools', 'upip_utarfile.py', opt=3)
freeze('$(MPY_DIR)/lib/lv_bindings/driver/linux', 'evdev.py')
freeze('$(MPY_DIR)/lib/lv_bindings/driver/linux', 'lv_timer.py')
freeze('$(MPY_DIR)/lib/lv_bindings/lib', 'display_driver_utils.py')
freeze('$(MPY_DIR)/lib/lv_bindings/lib', 'display_driver.py')
freeze('$(MPY_DIR)/lib/lv_bindings/lib', 'imagetools.py')
freeze('$(MPY_DIR)/lib/lv_bindings/lib', 'fs_driver.py')
freeze('$(MPY_DIR)/lib/lv_bindings/lib', 'lv_utils.py')

Another option is to remove the “native” and “viper” decorators from imagetools.py.

github.com

lvgl/lv_binding_micropython/blob/master/lib/imagetools.py

#
# Library of function for image manipulation.
# Can be used with lodepng to decode PNG images:
#
#     from imagetools import get_png_info, open_png
#     decoder = lv.img.decoder_create()
#     decoder.info_cb = get_png_info
#     decoder.open_cb = open_png
#
# Support transparency (alpha)
#
# TODO:
# - Support more color formats
#

import lvgl as lv
import lodepng as png
import struct

COLOR_SIZE = lv.color_t.__SIZE__

Removing decorators from imagetools.py allowed to build frozen_content.c, but it fails anyway later…

It seems that your compiler might be newer/more picky than expected. The warning there is probably valid, but you should be able to change -Werror to -Wno-error here to get past it.

wiklod · January 17, 2022, 10:41am

That worked out. Thank you!

@embeddedt @amirgon I fix it like this __attribute__((section(".text,\"ax\",@progbits # "))) ==> __attribute__((section("__TEXT,__text"))), it compiled, but i don’t know if any side effect in runtime!, any idea ?? I also try out your approach, but it doesn’t work fine also! !
many problems occur:
1.

No idea.
It’s not specific to lv_micropython, so it’s better to ask on the Micropython forum.

These are runtime problems, not related to the compile time problem on this thread.
I noticed that you opened another thread with the same problems, so let’s discuss it there.
