RHD256 Red Hat Linux Application Development and Porting

Provides a succinct introduction to new application development, as well as providing insight into porting existing applications, into the Red Hat Linux environment.

Prerequisites:

Application development skills on any UNIX-like platform, including proprietary offerings and other Linux distributions. Attendees are expected to be familiar with common shells and command line utilities such as the C compiler, a linker utility, and the make(1) program.

Course Outline

• Open source vs. the proprietary model
• The common Open Source software licenses: the GPL; the LGPL; and the BSD license; and how they affect your software development strategy.

• Packaging software with RPM and tar
• The CVS and Subversion version control systems
• How to compile and debug application programs using the GNU Compiler Collection and DDD
• How commonly-used enterprise file systems affect the application development effort.
• How to write, install, and control system services.
• The functional differences between Linux command-line tools and their proprietary-system counterparts.
• Using Red Hat Linux system libraries, and creating your own libraries
• Issues to be concerned with when porting applications to Red Hat Linux, such as little-endian vs. big-endian architectures.
• How Linux multithreaded applications are built.
• Linux security features such as PAM and OpenSSH.
• How to use the "/proc" filesystem to obtain system information.
• Advanced Linux features, such as asynchronous I/O.
