I'm currently using esp-open-rtos for my project.
I would like to add a webserver and have been looking at libesphttpd which seems really promising. I do however have some trouble with getting libesphttpd to compile using esp-open-rtos. Preferably i would like to compile it as an "extra" component. My current attempt at an component.mk file is as follows:

Code: Select all# Component makefile for extras/libesphttpd

libesphttpd_CFLAGS += "-std=gnu99"
libesphttpd_CFLAGS += "-ggdb"
libesphttpd_CFLAGS += "-Werror"
libesphttpd_CFLAGS += "-Wpointer-arith"

libesphttpd_CFLAGS += "-DICACHE_FLASH"
libesphttpd_CFLAGS += "-DHTTPD_MAX_CONNECTIONS=4"

libesphttpd_CFLAGS += "-DICACHE_FLASH_ATTR=__attribute__((section(\".irom0.text\")))"
libesphttpd_CFLAGS += "-DUSE_OPENSDK"

$(eval $(call component_compile_rules,libesphttpd))


I currently get the following error when compiling a project which includes the libesphttpd module

Do anyone have any experience with using libesphttpd together with esp-open-rtos and know how to write the component.mk in a sensible way? If so, any help will be very much appreciated.

Stefan
