Buildroot is a set of Makefiles and patches that simplifies and automates the process of building a complete and bootable Linux environment for an embedded system, while using cross-compilation to allow building for multiple target platforms on a single Linux-based development system.
Here is an example of ANSI C code that will generally cause a segmentation fault on platforms with memory protection. It attempts to modify a string literal, which is undefined behavior according to the ANSI C standard. Most compilers will not catch this at compile time, and instead compile this to executable code that will crash:
The Linux kernel and GNU C Library together form the Linux API. After compilation, the binaries offer an ABI . The glibc project was initially written mostly by Roland McGrath, working for the Free Software Foundation (FSF) in the summer of 1987 as a teenager.
Clang becomes default compiler for Android [53] (and later only compiler supported by Android NDK [54]). 13 March 2017 Clang 4.0.0 released: 26 July 2017: Clang becomes default compiler in OpenBSD 6.2 on amd64/i386. [55] 7 September 2017 Clang 5.0.0 released: 19 January 2018: Clang becomes default compiler in OpenBSD 6.3 on arm. [56] 5 March 2018
The Linux kernel notably makes wide use of self-modifying code; it does so to be able to distribute a single binary image for each major architecture (e.g. IA-32, x86-64, 32-bit ARM, ARM64...) while adapting the kernel code in memory during boot depending on the specific CPU model detected, e.g. to be able to take advantage of new CPU ...
Embeetle IDE - free, fast (non-eclipse) IDE. Works both on Linux and Windows. [16] emIDE by emide – free Visual Studio Style IDE including GNU Tools for ARM [17] GNU ARM Eclipse – A family of Eclipse CDT extensions and tools for GNU ARM development [13] GNU Tools (aka GCC) for ARM Embedded Processors by ARM Ltd – free GCC for bare metal ...
A high-level comparison of in-kernel and kernel-to-userspace APIs and ABIs The Linux kernel and GNU C Library define the Linux API. After compilation, the binaries offer an ABI. Keeping this ABI stable over a long time is important for ISVs. In computer software, an application binary interface (ABI) is an interface between two binary program ...
PREEMPT_RT was a set of patches for the Linux kernel which implement both hard and soft real-time computing capabilities. [1] On September 20, 2024, PREEMPT_RT was fully merged and enabled in mainline Linux on the supported architectures x86, x86_64, RISC-V and ARM64. [2] This will make kernel v6.12 the first release to include baked-in real ...
