Building a Project Using the SDK

Overview

The provided example applications can serve as a guide for creating a new project using the BMC C++ SDK. The examples are located in the examples directory, and the instructions to build and execute them are similar to those related with building the C++ SDK Library.

Step by Step Guide

Here is a step-by-step guide on how to build a project that uses the library:

1. Navigate to the directory containing the project that uses the BMC C++ SDK.

2. Ensure that the development environment is properly set up. To do this, follow the instructions in the Environment Setup section of our guide.

3. Create a CMakeLists.txt file in the root directory of the project. An example of this file can be found below.

4. Create a build directory inside the project.

5. Navigate to the build directory.

6. Configure CMake:

   • Linux/macOS

     cmake -DLIBRARY_PATH=[Path to the dir containing the library] -DINCLUDE_PATH=[Path to the dir containing the include files] ..

   • Windows 64

     cmake -DLIBRARY_PATH=[Path to the dir containing the library] -DINCLUDE_PATH=[Path to the dir containing the include files] .. -G "Visual Studio 17 2022" -A x64

   • Windows 32

     cmake -DLIBRARY_PATH=[Path to the dir containing the library] -DINCLUDE_PATH=[Path to the dir containing the include files] .. -G "Visual Studio 17 2022" -A win32

7. Build with CMake:

   cmake --build . --config Release

8. On Windows, verify that within the build directory, there is a Release (or Debug ) directory containing the project's executable. On Linux/macOS, look for the executable in the build directory.

CMake Example for Building Applications

Below is an example of a CMakeLists.txt file for building a sample application (i3c_cccs) that uses the BMC C++ SDK as a dynamic library:

cmake_minimum_required(VERSION 3.5)
project(MyProject)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)

# Accept library path as an argument
set(LIBRARY_PATH "" CACHE PATH "Path to the static library")

# Accept include path as an argument
set(INCLUDE_PATH "" CACHE PATH "Path to the include directory")

if(NOT LIBRARY_PATH)
  message(FATAL_ERROR "LIBRARY_PATH is empty")
endif()

if(NOT INCLUDE_PATH)
  message(FATAL_ERROR "INCLUDE_PATH is empty")
endif()

include(FetchContent)

add_executable(my_project
  main.cpp
)

set_target_properties(my_project PROPERTIES OUTPUT_NAME my_app)

# Include needed headers
target_include_directories(my_project PRIVATE 
  ${INCLUDE_PATH}
)

# Link against needed libraries
if(WIN32)
  target_link_libraries(my_project 
    nlohmann_json::nlohmann_json
    ${LIBRARY_PATH}/bmc_sdk.lib
  )
  # To link against the static library on Windows, use the following line instead:
  # target_link_libraries(my_project ${LIBRARY_PATH}/bmc_sdk_static.lib)
elseif(APPLE)
  target_link_libraries(my_project 
    nlohmann_json::nlohmann_json
    ${LIBRARY_PATH}/libbmc_sdk.dylib
  )
  # To link against the static library on macOS, use the following line instead:
  # target_link_libraries(my_project ${LIBRARY_PATH}/libbmc_sdk_static.a)
else()
  target_link_libraries(my_project 
    nlohmann_json::nlohmann_json
    ${LIBRARY_PATH}/libbmc_sdk.so
  )
  # To link against the static library on Linux, use the following line instead:
  # target_link_libraries(my_project ${LIBRARY_PATH}/libbmc_sdk_static.a)
endif()
