Mixing C and Assembly source code - IARSystems/cmake-tutorial GitHub Wiki

Introduction

This interactive example describes the configuration details for when, in a CMake project, a target is comprised of C sources (*.c) and Assembly sources (*.s).

Helpful Resources

project()
target_sources()

Interactive Example

A CMake project example is provided at examples/mix:

Project files
`CMakeLists.txt`
`fun.h`
`fun.s`
`main.c`

The public function fun() in fun.s returns 42 and is consumed by the application's main() function.

Tasks

Perform the following tasks on CMakeLists.txt (click to show/hide answers):

TODO 1: Enable Assembly for the project

project(Mix LANGUAGES C ASM)

TODO 2: Add fun.s source to the mix target in the CMakeLists.txt

target_sources(mix PRIVATE 
                   main.c
                   fun.s)

Finally build and test the project. Refer to the tutorial for more information.
