LittleFS compile errors on esp8266

Closed this issue 3 years ago · 4 comments

Great project!

I have a sketch that is using LittleFS and esp8266 arduino core 3.0.2. In sketch I include <FS.h> and <LittleFS.h>. To compile the project I use following command: make -f /home/karol/makeEspArduino/makeEspArduino.mk ESP_ROOT=/home/karol/esp8266 flash inside the folder that has .ino file.

I get following output:

~/code/esp8266-test/esp8266-test$ make -f /home/karol/makeEspArduino/makeEspArduino.mk ESP_ROOT=/home/karol/esp8266 flash

My config.mk

# config.mk
THIS_DIR := $(realpath $(dir $(realpath $(lastword $(MAKEFILE_LIST)))))
ROOT := $(THIS_DIR)/..
LIBS =  \
    $(ROOT)/lib/ArduinoJson \
    $(ROOT)/lib/WiFiManager \

FS_TYPE=LittleFS
BUILD_DIR ?= $(shell pwd)/build

VERBOSE = 1
USE_CCACHE = 1

COM = ttyUSB0
UPLOAD_SPEED = 921600

I'm not sure why there is 2_lfs.c and 2_lfs_util.c in my build folder. It seems that 2_lfs_util.c is a default config file, not sure what 2_lfs.c does.

Any ideas what I did wrong?

Fixed in latest commit

Answer 2 · 2022-01-13T20:04:27.000Z

Thank you, latest master works great!

I also noticed small bug in my config.mk, instead of FS_TYPE=LittleFS I should use FS_TYPE=littlefs because otherwise I get following error:

Yes, makeEspArduino searches for a application that matches that string in the tools directory.
A better error message should have been shown, will be fixed in next commit
