It looks like pigg y.so is consuming only 8K, but tucked away in this output is an anonymous mapping of 1032K. This is storage that was allocated for the bank array.

So linking with a shared object can force you to consume virtual memory that you otherwise would not use. If this data is truly unused, it may never actually consume physical memory or swap, although this range of virtual addresses is not usable by your process. This can become a problem if your process needs to allocate large blocks of memory.

. By default, the co jar barcode pdf417 mpiler uses dynamic linking, which means that if it can choose between a static library and a dynamic library, it will choose the dynamic library. If you want to link exclusively with static objects, you must specify the -static option to gcc/g++. Most development libraries come with copies of both a dynamic library and a static library for this purpose.

The linker cannot statically link an executable with a dynamic library, or vice versa.. Library Naming Con vention Dynamic libraries typically are identified by the .so extension of the filename. In Linux (and UNIX), dynamic libraries are also known as shared libraries or, more generically, as shared objects.

This is where the .so extension comes from. Static libraries use the .

a extension, which they inherited from the ar archive program with which they are created. To differentiate an ar archive (which is hardly used elsewhere) from a static library, library filenames are prefixed with the string "lib". So to create a static library named foo, name the file libfoo.

a. When the linker sees an argument such as -lfoo, it automatically searches for a file named libfoo.a in a predefined search path.

In keeping with tradition, dynamic libraries also use the lib prefix, so the linker will search for either libfoo.a or libfoo.so.

. 2 Building from Source The Build Process Now that you have awt pdf417 an understanding of the tools used to create projects, let s take a step back and examine how these tools work together. To keep it simple, we will focus on projects built with the C and/or C++ programming languages. C is most common because it generally is more portable than C++.

Although C++ is suitable for most projects, developers who want to reach the widest range of target systems will choose C. Believe it or not, there are even some programmers out there who don t know C++. Although the GNU compilers are commonly available on Linux systems, they are not necessarily required to build from source.

Open source projects, and GNU projects in particular, emphasize portability, so they don t necessarily require GNU compilers or Linux. The same code that builds and runs on Linux can also build and run on Solaris, IRIX, Free BSD, and even Windows. Portability isn t just a nice-to-have feature for anal-retentive developers; it s also vital to the survival of an open source project.

More platforms means more users and more developers looking at the code. That is a recipe for a better application..

The GNU Build Tools The GNU build syst PDF 417 for Java em is the de facto standard build tool for open source projects. It is a complex set of tools used by developers to generate source distributions that are easy to build and install. A typical source distribution created with the GNU build tools includes a configure script, which is used by the end user to create a Makefile.

As an end user, you don t need to know that these tools exist. You need only remember three simple steps to build any GNU program:.
