How do I update the cmake version in west to v3.22? How do I update gcc to v4.9 or clang to v3.3?

[Gavin He]

1，To develop 54H20 based on sdk v2.7.99-cs1, it is necessary to use a development kit provided by the customer. The cmake information of the development kit is as follows：

cmake_minimum_required(VERSION 3.22)
project(QLink)

FILE(GLOB_RECURSE SOURCES CONFIGURE_DEPENDS src/*.h src/*.c src/*.cpp headers/*.h)

add_library(QLink STATIC ${SOURCES})
target_include_directories(QLink PUBLIC ./headers)

target_compile_features(QLink PUBLIC cxx_std_11)

if(Qt6_FOUND)
    target_link_libraries(QLink PUBLIC Qt6::Core)
endif()

if(Qt6_FOUND AND QLINK_ENABLE_LOGGING)
    target_compile_definitions(QLink PUBLIC QLINK_ENABLE_LOGGING)
endif()

add_library(QLinkInternal INTERFACE)
target_include_directories(QLinkInternal INTERFACE src)

if(QLINK_ENABLE_TESTS)
    target_compile_definitions(QLink PUBLIC QLINK_ENABLE_TESTS)
endif()

2，A compilation error is reported with the following information

CMake Error at src/QLink/CMakeLists.txt:1 (cmake_minimum_required):
CMake 3.22 or higher is required.  You are running version 3.21.0

3， c++ related errors are also reported if cmake_minimum_required(VERSION 3.22) is changed to cmake_minimum_required(VERSION 3.20). According to the query information, gcc v4.9 or clang v3.3 is required to support it

target_compile_features no known features for CXX compiler

Thanks

Hi Gavin,

Have you updated the toolchain as well when you updated to v2.7.99-cs1.?

It is not recommended to update CMake, GCC and Clang manually..  Each SDK version comes with a toolchain that includes specific versions of CMake, GCC and Clang. Manually updating these might lead to compatibility issues.. Instead of manually updating individual components, please use the toolchain provided by the SDK version you're working with.

Also, Any reason as to why you want to develop based as NCS v2.7.99.? We have the latest v2.8.0 released and is available in the toolchain manager.. 

If you need to use a different SDK version that might include newer toolchain components, you can update the entire SDK using the Toolchain Manager as described in the [nRF Connect for VS Code documentation]: https://docs.nordicsemi.com/bundle/nrf-connect-vscode/page/guides/extension_migrate_sdk.html 

Remember that for the nRF54H20, you need to use the specific SDK version and the compatible DK version as mentioned in the [migration guide]: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_guide_nRF54H20_cs_to_2_7_99-cs1.html

Best Regards,

Swathy
