VS Code Path Problem

[lukehoersten]

I've had this working with the normal CLI install.sh and export.sh scripts and now am trying to get it working with VS Code with no luck. The following are my settings and the resulting CMake error output.

How are you building ?

Are you using the extension commands to build ? Press menu View -> Command Palette -> type ESP-IDF: Build your project

Please review Vscode extension commands

[lukehoersten]

The extension's build was broken for me until I followed the fix here:
https://github.com/espressif/vscode-esp ... issues/339

Now I'm still not able to get the esp-homekit-sdk linked but the build process actually finds the compilers and works.

Should this not be enough?:

Makefile

Code: Select all

HOMEKIT_PATH ?= $(abspath $(IDF_PATH)/../../esp-homekit-sdk)
COMMON_COMPONENT_PATH ?= $(HOMEKIT_PATH)/examples/common

PROJECT_NAME := esp-homekit-door
EXTRA_COMPONENT_DIRS += $(HOMEKIT_PATH)/components
EXTRA_COMPONENT_DIRS += $(HOMEKIT_PATH)/components/homekit
EXTRA_COMPONENT_DIRS += $(COMMON_COMPONENT_PATH)

include $(IDF_PATH)/make/project.mk

CMakeLists.txt

Code: Select all

cmake_minimum_required(VERSION 3.5)

if(DEFINED ENV{HOMEKIT_PATH})
  set(HOMEKIT_PATH $ENV{HOMEKIT_PATH})
else()
  set(HOMEKIT_PATH ${CMAKE_CURRENT_LIST_DIR}/../..)
endif(DEFINED ENV{HOMEKIT_PATH})

set(EXTRA_COMPONENT_DIRS ${HOMEKIT_PATH}/components ${HOMEKIT_PATH}/components/homekit ${CMAKE_CURRENT_LIST_DIR}/../common)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(esp-homekit-door)

Hi @ lukehoersten sorry about the build issue.

With regards to your problem, means you can't add the HomeKit_path to your build ? Where are you defining the HOMEKIT_PATH variable ? is it a global system environment variable or extension specific env variable ?

Is there any error in the build output ?

[lukehoersten]

It's defined in the Makefile:

Code: Select all

HOMEKIT_PATH ?= $(abspath $(IDF_PATH)/../esp-homekit-sdk)

[lukehoersten]

Got it working. Once I fixed the ESP specific build, I had to regenerate my CMAKE from my Makefile now it all works. Thanks for you help!

How did you solved the problem, can you be more especific?
I have a similar problem.

Thanks.
