How to compile AzureSphere samples in Linux command line

Gergo Santha 0

Hi!

I'd like to build my AzureSphere images automated using Python scripts on Linux. Unfortunately, I could not find a way how to do it. Any help would be great! Thank you!

Hello Ashok,

thank you for your help. What I want to do is to build my project from Linux command line (and later from a script). I modified the CMakeLists file to the following (I replaced 'x' where confidential):

#  Licensed under the MIT License.

cmake_minimum_required(VERSION 3.10)

project(AzureIoT C)

if (UNIX)
    include(/opt/azurespheresdk/CMakeFiles/AzureSphereToolchain.cmake)
    azsphere_configure_tools(TOOLS_REVISION "20.07")
    azsphere_configure_api(TARGET_API_SET "16")
endif (UNIX)

if(WIN32)
    azsphere_configure_tools(TOOLS_REVISION "20.07")
    azsphere_configure_api(TARGET_API_SET "16")
endif (WIN32)

        DEPENDS ${CMAKE_SOURCE_DIR}/app_manifest.json)
else()
    # Warn users without PowerShell to update their manifest
    add_custom_target(ValidateManifest ALL
        COMMAND echo "Please ensure that you have updated app_manifest.json as described in IoTCentral.md or IoTHub.md, as appropriate."
        DEPENDS ${CMAKE_SOURCE_DIR}/app_manifest.json)
endif()

add_dependencies(ValidateManifest ${PROJECT_NAME})

azsphere_target_add_image_package(${PROJECT_NAME} RESOURCE_FILES "Certs/x")

Building with 'cmake --build . --clean-first' gives the follwing error: "

CMake Error at /opt/azurespheresdk/CMakeFiles/AzureSphereToolchainBase.cmake:2 (message):
  Azure Sphere CMake projects must use the Ninja generator
Call Stack (most recent call first):
  /opt/azurespheresdk/CMakeFiles/AzureSphereToolchain.cmake:41 (include)
  CMakeLists.txt:9 (include)

From this point it is not clear how to proceed.

Is Ninja installed and available in your path? If so, you'll need to add -G Ninja as an argument to cmake.

Alternately, you can make use of the CMake presets (CMakePresets.json) that are part of each Azure Sphere project. This is described in the documentation here: https://learn.microsoft.com/en-us/azure-sphere/app-development/build-hl-app?view=azure-sphere-legacy&tabs=windows%2Ccliv2beta&pivots=cli#build-the-application

For future reference, the pivot tabs at the top of the page allow you to swap between different environments. Note that the CLI "pivot" is selected in the image below.
