- Sun Nov 15, 2015 8:08 pm #34142 Hi There, how are you?

I am trying to compile the ESP-LINK v1.04: https://github.com/jeelabs/esp-link/releases/tag/v1.0.4
I am using the Windows + Eclipse devkit with SDK v1.3.0. A made a few changes to the Makefile to compile as follows. However, I am getting this error:

mingw32-make.exe: *** No rule to make target 'html/', needed by 'build/espfs_img.o'. Stop.

Please refer to the screenshot, it does most of the job, it just gets stuck with this small problem. Any ideas of what can be causing it?

Code: Select all#
# Makefile for esp-link - https://github.com/jeelabs/esp-link
#
# Start by setting the directories for the toolchain a few lines down
# the default target will build the firmware images
# `make flash` will flash the esp serially
# `make wiflash` will flash the esp over wifi
# `VERBOSE=1 make ...` will print debug info
# `ESP_HOSTNAME=my.esp.example.com make wiflash` is an easy way to override a variable
#

# --------------- esphttpd config options ---------------

# If GZIP_COMPRESSION is set to "yes" then the static css, js, and html files will be compressed
# with gzip before added to the espfs image and will be served with gzip Content-Encoding header.
# This could speed up the downloading of these files, but might break compatibility with older
# web browsers not supporting gzip encoding because Accept-Encoding is simply ignored.
# Enable this option if you have large static files to serve (for e.g. JQuery, Twitter bootstrap)
# By default only js, css and html files are compressed using heatshrink.
# If you have text based static files with different extensions what you want to serve compressed
# then you will need to add the extension to the following places:
# - Add the extension to this Makefile at the webpages.espfs target to the find command
# - Add the extension to the gzippedFileTypes array in the user/httpd.c file
#
# Adding JPG or PNG files (and any other compressed formats) is not recommended, because GZIP
# compression does not work effectively on compressed files.

#Static gzipping is disabled by default.

# If COMPRESS_W_YUI is set to "yes" then the static css and js files will be compressed with
# yui-compressor. This option works only when GZIP_COMPRESSION is set to "yes".
