I was recommended this book in a reply to a Stackoverflow question , and I am not disappointed. The book goes occasionally perhaps a little bit too much into technical details, which I felt could be safely skipped. Perhaps a case study, i. Until I read this book I simply did not understand how a program actually ran on my computer.
A few details are still a bit fuzzy, but now I feel much better equipped for dealing with obscure linker errors or custom linker scripts. Highly recommended for any programmer who wants to get to the bottom of things. On one hand, I found this book to be really hard to read, but at a second glance, I can't really say there is anything wrong with it except for a two points: 1.
It's 15 years old. This is a pretty big deal to me because it's hard to tell what's still useful and what has been deprecated. There' This is a hard book for me to rate. There's ample discussion of Unix System V, for instance, and some now-mostly-deprecated file formats, like a. It feels sort of haphazardly organized. Some of the sections have odd or off-topic subsections, and I think it could be better organized. Linkers and Loaders by John R. Whatever your programming language, whatever your platform, you probably tap into linker and loader functions all the time.

But do you know how to use them to their greatest possible advantage? The book begins wi Whatever your programming language, whatever your platform, you probably tap into linker and loader functions all the time. The book begins with a detailed and comparative account of linking and loading that illustrates the differences among various compilers and operating systems. On top of this foundation, the author presents clear practical advice to help you create faster, cleaner code.
You'll learn to avoid the pitfalls associated with Windows DLLs, take advantage of the space-saving, performance-improving techniques supported by many modern linkers, make the best use of the UNIX ELF library scheme, and much more.
If you're serious about programming, you'll devour this unique guide to one of the field's least understood topics. Get A Copy. Paperback , pages. More Details Original Title. Other Editions 5. Friend Reviews. To see what your friends thought of this book, please sign up.

Published in , it covers Linux ELF and a. Pretty much the only book of it's kind and a great primer if you're interested in writing your own linker or loader for an OS or just need to better understand native executables. My only semi-complaint is that it spent a lot of pages talking about real mode but being published in , we were less than a decade removed from that fever dream of backwards compatibility.
Jan 21, Michael Pankov rated it it was ok Shelves: You barely can understand linkers by this book since it falls into implementation details of each specific OS and CPU too early. In the end, the book presents recollection of dirty hacks from existing and dated implementation, however with explanations why there're these hacks in the first place.
But I'd rather have a book on design of new linkers and loaders, or at least in-depth analysis of at least one loader.
I understand new loaders are very rarely designed, but anyway, this book is of no You barely can understand linkers by this book since it falls into implementation details of each specific OS and CPU too early. I understand new loaders are very rarely designed, but anyway, this book is of no help when they do.

Mar 22, Claudiu rated it liked it. Although very old, this is probably the book on the present subject.
The book itself is not necessarily outdated, because the principles haven't changed, but the description of some file formats is certainly outdated. Thus there is some prerequisite knowledge the author assumes you already have. I think an Operating Syst Although very old, this is probably the book on the present subject.
I think an Operating Systems course and at least a basic understanding of assembly language and related knowledge like registries, counters, stack, etc. Although I am a practicing C programmer and I consider I have the aforementioned knowledge, there were still parts of the book I didn't understand.
What I didn't like is that you can't read only the parts of the book that interests you, because the author is often referencing previous information from the book. Nov 18, Jason Copenhaver rated it it was amazing. The Book of Why: The New Science of Cause and Effect.

I've been around compilers, code generation, and object formats enough that this was mostly a refresher - but I did like some of the historical references and notes on atypical processors.
Linkers and Loaders
I think this works at a good level of detail for experienced programmers who can fill in the blanks for things like relocation records that identify which bit positions need to be set. An experienced programmer will also have used symbolic debuggers, and will have a fair idea of what those tools expect to find in an executable image.
I found discussion of linker scripts a bit thin, though - on one embedded application, I think I wrote more lines of linker scripts than of assembler. The author does mention things like linking a piece of code to run at address X but storing it in memory at address Y.
You'll need this, for example, when your processor has a small but fast on-chip RAM address X , and you have a few different code fragments stored at addresses Y you'll be loading into that buffer at different times. It also doesn't mention useful things like defining a symbol at the linker instead of the application code - helpful when coding to a memory mapped device that might live at different addresses in different application configurations.
I also used this this feature with the GNU linker and this command line option: That embeds the build time in the application - not as a value stored in memory, but as the address of the buildDateTime symbol which then gets cast to a time value. This does mention overlays, which can still be life-savers when coding a large application for a small e. That disappointed me because I've found the concept helpful in small address spaces with larger ROMs where, for example, something like overlays could be used for internationalization.
With a helpful bus controller, you could swap between UI messages in different languages by choosing which languages' message overlay appears in the address space at any given time.
No text can cover everything. For example, this omits the "cmpexe" compound executable format used in the Apollo Domain system. The one runnable file actually held code in two different instruction sets, so one program file could be used on both the x0 or the "Prism" processor architectures - the loader just chose which side of the program to run.
Heterogeneous environments like that have been rarities, but the idea remains interesting. I was also involved in design of a microcode linker, where addresses were not numbers but bit-strings. Since sequential addresses had little meaning, individual instructions from different input segments could be interleaved, subject to bit pattern constraints on micro-addresses.
Historical exotica aside, this gives a strong foundation in the basic concepts of linking and loading. It offers just enough of a look at CPU hardware to show how instruction formats and memory characteristics affect the process.
It also presents a nice progression from simpler to more complex object formats, and the reasons for them. I imagine this as a useful adjunct to a college course in compilers or operating systems, and helpful to professionals self-teaching about what's "under the hood" in familiar programming tools.
Highly recommended, but you might outgrow it quickly once you start working on the tools yourself. This book is the only one of its kind. It describes how linkers and loaders work. Most books describe the compilation process, where the text source code becomes machine code.
However, this is the only one that describes how those compiled objects with machine code are glued together. But this book is seriously dated and some parts are too hard to understand. I found the chapter 7 of "Computer Systems: A Programmer's Perspective" better than this one whole book.
