The Compilation Toolchain Cross-Compilation for Embedded Systems Prof. Andrea Marongiu ([email protected]) Toolchain The toolchain is a set of development tools used in association with source code or binaries generated from the source code • Enables development in a programming language (e.g., C/C++) • It is used for a lot of operations such as a) Compilation b) Preparing Libraries Most common toolchain is the c) Reading a binary file (or part of it) GNU toolchain which is part of d) Debugging the GNU project • Normally it contains a) Compiler : Generate object files from source code files b) Linker: Link object files together to build a binary file c) Library Archiver: To group a set of object files into a library file d) Debugger: To debug the binary file while running e) And other tools The GNU Toolchain GNU (GNU’s Not Unix) The GNU toolchain has played a vital role in the development of the Linux kernel, BSD, and software for embedded systems. The GNU project produced a set of programming tools. Parts of the toolchain we will use are: -gcc: (GNU Compiler Collection): suite of compilers for many programming languages -binutils: Suite of tools including linker (ld), assembler (gas) -gdb: Code debugging tool -libc: Subset of standard C library (assuming a C compiler). -bash: free Unix shell (Bourne-again shell). Default shell on GNU/Linux systems and Mac OSX. Also ported to Microsoft Windows. -make: automation tool for compilation and build Program development tools The process of converting source code to an executable binary image requires several steps, each with its own tool. -

They all use a common back-end which produces assembler code which is fed to the GNU assembler. It is available at http://gcc.gnu.org/. * C library: A standardized API based on the POSIX specification which is the principle interface to the operating system kernel from applications.

EECS 373: Design of Microprocessor-Based Systems Fall 2012 Lecture 3: Toolchains Instructor: Prabal Dutta Date: October 2, 2012 Note: Unless otherwise specified, these notes assume: (i) an ARM Cortex-M3 processor operating in little endian mode; (ii) the ARM EABI application binary interface; and (iii) the GNU GCC toolchain. Toolchains A complete software toolchain includes programs to convert source code into binary machine code, link together separately assembled/compiled code modules, disassemble the binaries, and convert their formats. Binary program file (.bin) Assembly Object Executable files (.s) files (.o) image file objcopy ld (linker) as objdump (assembler) Memory layout Disassembled Linker code (.lst) script (.ld) Figure 0.1: Assembler Toolchain. A typical GNU (GNU's Not Unix) assembler toolchain includes several programs that interact as shown in Figure 0.1 and perform the following functions: • as is the assembler and it converts human-readable assembly language programs into binary machine language code. It typically takes as input .s assembly files and outputs .o object files. • ld is the linker and it is used to combine multiple object files by resolving their external symbol references and relocating their data sections, and outputting a single executable file. It typically takes as input .o object files and .ld linker scripts and outputs .out executable files. • objcopy is a translation utility that copies and converts the contents of an object file from one format (e.g. .out) another (e.g. .bin). • objdump is a disassembler but it can also display various other information about object files. It is often used to disassemble binary files (e.g. -

Debian Med Integrated Software Environment for All Medical Purposes Based on Debian GNU/Linux
Debian Med Integrated software environment for all medical purposes based on Debian GNU/Linux Andreas Tille Debian OSWC, Malaga 2008 1 / 18 Structure 1 What is Debian Med 2 Realisation 3 Debian Med for service providers 2 / 18 Motivation Free Software in medicine not widely established yet Some subareas well covered Medical data processing more than just practice and patient management Preclinical research of microbiology and genetics as well as medical imaging ! Pool of existing free medical software 3 / 18 Profile of the envisaged user Focus on medicine not computers Unreasonable effort to install upstream programs No interest in administration Interest reduced onto free medical software Easy usage Security and confidence Native-language documentation and interface 4 / 18 Customising Debian Debian > 20000 packages Focus on medical subset of those packages Packaging and integrating other medical software Easy installation and configuration Maintaining a general infrastructure for medical users General overview about free medical software Propagate the idea of Free Software in medicine Completely integrated into Debian - no fork 5 / 18 Special applications 6 / 18 Basic ideas Do not make a separate distribution but make Debian fit for medical care No development of medical software - just smooth integration of third-party software Debian-Developer = missing link between upstream author and user 7 / 18 Debian - adaptable for any purpose? Developed by more than 1000 volunteers Flexible, not bound on commercial interest Strict rules (policy) glue all things together Common interest of each individual developer: Get the best operating system for himself. Some developers work in the field of medicine In contrast to employees of companies every single Debian developer has the freedom and ability to realize his vision Every developer is able to influence the development of Debian - he just has to do it. -
