![]() ![]() The first line sets the minimum version of CMake required to build this project to version 3.0. Set(CMAKE_FIND_ROOT_PATH /path/to/rootfs/) ![]() Set(CMAKE_CXX_COMPILER /usr/bin/aarch64-linux-gnu-g++) Set(CMAKE_C_COMPILER /usr/bin/aarch64-linux-gnu-gcc) To cross-compile your C++ program with CMake, create a new file called CMakeLists.txt and fill it with the following: # CMakeLists.txt Make sure you use the exact paths for these on your machine.Īfter extracting the content of the image, the cross-compilation environment should now be set up. The final copy command extracts the contents of this image to /path/to/rootfs. ![]() Substitute /path/to/iso/ with the actual path of the downloaded ISO image. Sudo mkdir /mnt/iso sudo mount -o loop /path/to/iso /mnt/iso sudo cp -r /mnt/iso/* /path/to/rootfs/ You can install GCC on Debian/Ubuntu using the following command: To do this, you need two tools: the GNU make utility and GCC. To start, you need to create a simple C++ program and then build it using Makefiles and GCC. In this tutorial, you’ll learn how to build a simple C++ program and then cross-compile it for AArch64 or ARM64-based devices using CMake and GCC. CMake is a robust build system generator that uses configuration files to create cross-compiled binaries, and GCC is a toolchain that includes compilers for various programming languages, including C, C++, Objective C, and Fortran. When cross-compiling your software, CMake and the GNU Compiler Collection (GCC) can be helpful. For example, with cross-compilation, you can compile a binary for ARM-based devices like a Raspberry Pi on your standard x86-64 development machine. This enables developers to build binaries for different architectures without using those specific architectures themselves. If you want to see what can be done by combining ideas from a Makefile and a Dockerfile, then check us out.Ĭross-compilation is the process of compiling your program on a different host than the target system. This article covers cross-compiling binaries using CMake and GCC. We make building software simpler-and faster-using containerization. ![]()
