Hello,

I'm using MSYS2 to compile and flash the ESP32.
My ESP-IDF library is defined as C:\msys32\home\user\esp\esp-idf
I need to include a header file which is located in a common library (for another project to use).
The header file is located in another drive D:\project\common
I tried to use EXTRA_COMPONENT_DIRS in makefile and tried some other stuff like COMPONENT_SRCDIRS & COMPONENT_ADD_INCLUDEDIRS for component.mk with no success. what I'm I doing wrong?
what is the difference between makfile, *.mk file and CMakeLists.txt which located in different libraries (when I'm using one of the examples)?

Thank you,

Hi,

Thank you for your reply,

My project tree:
i2c_esp32 dir--->
------------------CmakeLists.txt
------------------sdkconfig
------------------Makefile
------------------main dir --->
-------------------------CmakeLists.txt
-------------------------component.mk
-------------------------i2c_example_main.c
-------------------------kconfig.projbuild
------------------components dir --->
-------------------------CmakeLists.txt
-------------------------component.mk
-------------------------i2c_ctrl.c
-------------------------include dir --->
------------------------- i2c_ctrl.h


The file I want to include as I stated located in D:\project\common
right now I just copied the file to component\include directory to bypass the problem.
i2c_ctrl.h and i2c_example_main.c use #include to include the common file and use it.

Files contents:
i2c_esp32 dir--->
CmakeLists.txt:
# The following lines of boilerplate have to be in your project's CMakeLists
# in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
#set(EXTRA_COMPONENT_DIRS "$ENV{COMMON_PATH}")
project(i2c-example)

Makefile:
#
# This is a project Makefile. It is assumed the directory this Makefile resides in is a
# project subdirectory.
#

PROJECT_NAME := i2c-example
#EXTRA_COMPONENT_DIRS := COMMON_PATH
#COMPONENT_DIRS += $(COMMON_PATH)

include $(IDF_PATH)/make/project.mk

COMMON_PATH defined as D:\project\common using file .sh located in c:\msys2\etc\profile.d

main dir --->
CmakeLists.txt:
set(COMPONENT_SRCS "i2c_example_main.c")
set(COMPONENT_ADD_INCLUDEDIRS ".")
set(COMPONENT_PRIV_REQUIRES "/d/Projects/common") another thing I tried.
register_component()

component.mk
COMPONENT_ADD_INCLUDEDIRS += $(COMMON_PATH)

components dir --->
CmakeLists.txt
#
# Component Makefile
#
COMPONENT_ADD_INCLUDEDIRS := include
set(COMPONENT_SRCS "i2c_ctrl.c")
component.mk
#
# Component Makefile
#
COMPONENT_SRCDIRS += include
COMPONENT_ADD_INCLUDEDIRS += include

Can you please help my figure it out?

Still,

I need to figure it out soon - my company needs to deliver the software asap and this problem influence the schedule.
Please help if you can,

Thank you

Hi,

Thanks again,
Where can I see the error logs? or do you mean the compilation error?

I posted the project tree - which file should be changed (project dir has Makefile & CmakeLists.txt, main dir has component.mk & CmakeLists.txt, component dir has component.mk & CmakeLists.txt)? What is the exact command I should use? my tests and tries are not important - lets start fresh, what should be written exactly according to the PATH i posted?

My ESP-IDF version:
v4.0-dev-478-gdf61612f8-dirty

Thank you very much,
