An Introduction To Linux Development Environment
This document provides an overview of the Linux development environment and its components. It discusses how Linux benefits programmers through open source collaboration and access to code. Embedded systems are highlighted as a major application area for Linux due to its customizability and low memory usage. The key components of a Linux development platform are outlined, including editors, compilers, linkers, debuggers, version control systems, and documentation tools.

- 3. Introduction Linux &Programming have inherit relationship. Linux is an open “ source code” software . Linux made by programmers, having in mind other programmers. Best of the kind programming tools come free with Linux.
- 4. How does itaffect programmers’ life? Make an unrefined idea to a big Open Source project. Share your idea and code fragments. Gather a team of volunteers from all over the word. Get donations for your basic idea and team leadership.
- 5. How does itaffect programmers’ life? ( cont’d ) Take advantage of free testers, debuggers, documenters and developers. Some users may see your work and become real customers: Some may need support and training. Sign a financial contract with those who need a customized version of your system.
- 6. How does itaffect programmers’ life? ( vice versa ) You are forced by your employer to do a huge project with an early deadline. You search the web for similar previously done work. You likely find a close work and make some changes and will be able to meet the deadline.
- 7. How does itaffect programmers’ life? ( cont’d ) You gain benefit of other efforts as others of yours: Cooperation Learn from elegant codes of professionals. Improve your coding and team working skills by joining big Open Source projects.
- 8. Applications & benefitsOpen Source returns freedom and authority to the customer. Change software according to your desire. Integrate existing software systems to a new one. (System Integration) Add new features to your software. (e.g. Persian support)
- 9. Applications & benefits( cont’d ) Building applications from source has some advantages in comparison with binary distributions: Performance tuning (e.g. compiling & customizing Linux kernel) Hardware fitting Minimizing size and features can lead to more security and better performance.
- 10. Applications & benefits( cont’d ) Some applications are normally distributed as source and should be build/ported on host machine. Solve software bugs yourself instead of bug report and waiting to be fixed in later releases. Write device driver for your specialized hardware embedded systems
- 11. What are embeddedsystems? A combination of computer hardware and software dedicated to specific tasks. In contrast with general-purpose software/hardware Limited hardware capabilities: generally lack of memory space, power supply and fast processors Customized, minimized and crash-protected Operating System and applications are needed.

- 13. Embedded systems andLinux Linux as an operating system can act greatly as heart of Embedded system software. Access to code make it easy to customize and minimize the Linux kernel so that it can be put on a ROM. It can be changed to fit specific hardware. (e.g. through writing device drivers)
- 14. Embedded systems andLinux ( cont’d ) Windows CE: not a great competitor Linux architecture makes it a suitable choice: Access to source code Easy customization Low memory consumption No built-in GUI Built-in firewall and router Many freely availabe embedded applications …
