This keyword when making a library! CMake goes into an old compatibility mode for this target that Target_link_libraries and a keyword one of PUBLIC, PRIVATE, and INTERFACE. Once you have several targets, you can describe the relationship between them with More on that later, once we see what we can do with targets. To make the default is sort-of an вЂњautoвЂќ library that is user selectable with BUILD_SHARED_LIBS. Now that the CMake build files have been written to the build directory, you run make in that directory to create the executable.You can add the keywords STATIC, SHARED, or MODULE if you know what kind of library you want в”‚ в”‚ в”њв”Ђв”Ђ CMakeDetermineCompilerABI_CXX.bin If you look at the /build directory, youвЂ™ll see the following structure: build Build files have been written to: /Users/charath/C/multiply_example/build Check for working CXX compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ - skipped

To get us a headstart on the goals of this article, we will set up a function to execute the multiplication. It doesnвЂ™t get any more simple (trivial?) than that. Let us look at a simple C program - one that takes an integer, multiples it by another integer, and prints out the result of that multiplication. Let us look at what it takes to build an INTERFACE library with a simple example. This allows for faster and smaller binaries, in addition of course to the ability to remove support for unwanted features from your executable entirely. enabling/disabling assertions, setting the sizes of static buffers), on a per-application basis, at compile time. Building in this way allows your build configuration to specify customised settings for those libraries (e.g.

When building an executable with the SDK, all of the code for one executable, including the SDK libraries, is (re)compiled for that executable from source. By giving the user significant control over the build process, INTERFACE libraries ensure that the executable that is built is optimized for the constraints of the device on which it runs.

With the relatively tight constraints imposed on applications by microntroller platforms, finer control of the build process becomes necessary.Д¬Make INTERFACE libraries are one way to achieve this objective. However, this does not give the programmer a great deal of control on the build settings and this can impact the size of the executable. Traditionally, C development has used either statically or dynamically linked libraries to build executables. Dependencies (on other INTERFACE libraries).Compiler definitions (visible to code as #defines).

The Pico C SDK Reference defines a CMake INTERFACE library as a collection of: In this first part of a 3-part tutorial, we set up a simple CMake environment and create a simple C program which we will use as an example.

In this article, we will determine what is an Interface library, and how to write a simple one so that we can use it as a model for future development on the Pico. The entire C SDK for the Pico is created as a set of CMake Interface libraries.
