Unable to include Library

[DutchOrange]

So I was trying to include the "led_strip.h" Libary but I just cant get it working. Alsways getting the error:

../main/Reciver.c:14:10: fatal error: led_strip.h: No such file or directory
#include "led_strip.h"

Here is my CMmake in the project folder:

Code: Select all

# The following four lines of boilerplate have to be in your project's CMakeLists From Reviver 
# in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)   

set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/esp-idf-lib/components)
#set(EXTRA_COMPONENT_DIRS ${CMAKE_CURRENT_SOURCE_DIR}/../../components)


include($ENV{MDF_PATH}/project.cmake)
#include($ENV{IDF_PATH}/tools/cmake/project.cmake)


project(Node_reciver)

And here is the CMake in the main folder:

Code: Select all

idf_component_register(SRCS "Reciver.c"
                    INCLUDE_DIRS "."
		    REQUIRES mcommon mconfig mwifi mlink
)

Any ideas what else ?
Thanks

Do you have a led_strip.h, and if so, where is it located?

[DutchOrange]

Here is the full path to it

E:\Desktop\MDF\esp-mdf\esp-idf-lib\components\led_strip

The best option is to put the "led_strip.h" file in the same folder where your main file ("Reciver.c" in your case) is located.

If the "led_strip.h" file is linked with a "led_strip.c" file, you must copy them both, and the CMake file would be as follows:

Code: Select all

idf_component_register(SRCS "Reciver.c"
                            "led_strip.c"
                    INCLUDE_DIRS "."
		    REQUIRES mcommon mconfig mwifi mlink
)

E:\Desktop\MDF\esp-mdf\esp-idf-lib\components\led_strip

Thanks, so you're effectively making the led_strip thing into a component. Do you also have a CMakeLists.txt in that directory? If so, can you post its contents?

[DutchOrange]

So here is the CmakeList in " E:\Desktop\MDF\esp-mdf\esp-idf-lib\components\led_strip " Directory

Code: Select all

idf_component_register(
    SRCS "led_strip.c"
    INCLUDE_DIRS .
    REQUIRES log esp_idf_lib_helpers
)

Also a bit off topic but what is the difference of

Code: Select all

INCLUDE_DIRS .
INCLUDE_DIRS "."
INCLUDE_DIRS " "

Thanks for the help

                    INCLUDE_DIRS "."
		    REQUIRES mcommon mconfig mwifi mlink
)

Would that go into the "main" folder ? and wouldn't it need anything more / How would I link it ?

As you have said, you have already put #include "led_strip.h" in your main code.
So you only need to put led_strip.h and led_strip.c in the same folder where you have the main code. And do that little modification in the CMake file.
It should work.

Thank you, It seems to have worked perfectly.

This worked for me

just add the following line in CMakeLists.txt

Code: [Select all] [Expand/Collapse]

1. set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/led_strip)

It looks something like this

Code: [Select all] [Expand/Collapse]

1. # The following lines of boilerplate have to be in your project's
2. # CMakeLists in this exact order for cmake to work correctly
3. cmake_minimum_required(VERSION 3.5)
4.  
5. set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/led_strip)
6.  
7. include($ENV{IDF_PATH}/tools/cmake/project.cmake)
8. project(hello_world)
