Cross-Compiling for Raspberry Pi: Getting Started and Troubleshooting
Blog post from Earthly
The article provides a detailed guide on setting up a cross-compiling environment for Raspberry Pi using a host machine running Ubuntu. It covers the steps to configure SSH, prepare the development machine, create a Raspbian root file system, and install an appropriate toolchain for cross-compilation. The tutorial emphasizes the challenges of compiling large projects directly on Raspberry Pi, especially lower-end models, and suggests using a more powerful host machine for efficiency. It walks through the process of writing and compiling a C++ program using CMake, linking it with shared libraries like GMP, and transferring the executable to the Raspberry Pi. Additionally, it discusses debugging techniques using GDB and addresses common errors encountered during the cross-compilation process. The article concludes by highlighting the benefits of cross-compilation for optimizing development on resource-constrained devices like the Raspberry Pi.
