It adds a dependency between DL and offsets_h.

offsets_h is a target that happens to depend on various kernel headers, including syscall_list.h, which evidently was used by the application library.

I'm not aware of any such example.

Hi,

Thank you for your reply. It's working.

What does add_dependencies(DL offsets_h) do?

Is there any zephyr cmake example using multiple CMakeLists I can read?

Thanks for your help!

You also need

add_dependencies(DL offsets_h)

Hi,

By adding target_link_libraries(DL PRIVATE zephyr_interface)

I still have the following issue

fatal error: syscall_list.h: No such file or directory

Maybe adding

target_link_libraries(DL PRIVATE zephyr_interface)


To your 2nd CMake file could help?

Hi everyone,

I am currently working on the Zephyr OS with a FDRM_K64f board from NXP.

I want to create my own application using cmake as recommended by the documentation.

However I don't want to put everything in one CMakeLists.txt. I want to break down my project into libraries (multiple CMakeLists.txt).

Do you know if there is any documentation talking about that?

My top CMakeLists looks like that:

cmake_minimum_required(VERSION 3.8.2)

include($ENV{ZEPHYR_BASE}/cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
project(NONE)


add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/DataLinkLayer
${CMAKE_CURRENT_SOURCE_DIR}/build/${BOARD}/DataLinkLayer)

target_sources(app PRIVATE src/main.c)

target_link_libraries(app
PRIVATE DL
)


And my second CMakeLists (under the folder DataLinkLayer) looks like that:

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/src)

add_library(DL src/DataLinkInterface.c)

target_include_directories(DL
INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/Interface)



The issue is I can include the boilerplate.cmake in only one CMakeLists.txt otherwise It's not working, But, the second CmakeLists doesn't know the zephyr library..

I tried to add: include_directories(/home/user/zephyr/include) in the second CMakeLists but it is not enough. Do you know what should I do?


Thank you,
