Increasingly, developers, architects, and project managers face the challenge of porting their C, C++, and Java applications from UNIXR to LinuxR environments. Now, there's a definitive, start-to-finish guide to porting applications from today's most widely used UNIX platforms: SolarisT, HP-UX, and AIXR.

Three of IBM's most-experienced Linux porting specialists lead you through your entire project: scoping, analysis, recoding, and testing. They present a start-to-finish porting methodology, realistic discussions of key porting tasks, and a questionnaire for assessing the work involved in any new project. You'll discover what Linux offers in terms of APIs, library functions, versioning, system features, and tools-and the implications for your project. Next, the authors address each individual UNIXR platform in detail, identifying specific porting challenges and best-practice solutions. Coverage includes:

* Understanding the Linux environment: GNU binutils, Java environments, shells, packaging options, and more
* Uncovering and addressing project unknowns, variables, and other risks
* Handling specific platform differences: standards, compilers, linkers, versioning, system/library calls, threads, and more
* Testing and debugging ported applications using the GNU debugger and Linux memory leak and performance tracing tools
* Contains quick references to UNIXR and Linux APIs, compilers, and linker options, and a discussion of porting issues unique to IBM's POWERT architecture

Whether you need a start-to-finish guide or a concise reference, you'll find this book an indispensable resource for all your UNIXR-to-Linux porting projects.
