copied!<p>A statically executable contains all the objects that it needs so no external DLL will be called when executed. The advantaje is that is is portable accross a lot of platforms no matter what version of DLLs have been installed on that system. The BIG disadvantage is that you are probable wasting disk space since you are including in your executable code that is already present in system/external DLLs. Moreover I think, but I'm not very sure, that DLLs are loaded in main memory only once, no matter how many executables are using them, but if you link statically the library objects inside your executable you load the same code twice (one for the DLL used by the rest of the programs and one for your executable). On the other hand this could be an advantage instead a disatvadvantage, since the executable contains only the objects of the external libraries that it needs, not the whole library. A DLL is loaded in memory as a whole when an application needs it.</p> <p>Static linking is ideal to compile small apps that you want to carry from one system to another as a small tool. I.e. it was really useful for me to have a statically compiled version of tcpdump when it was not included in every Linux distro. It was bound to work on every Linux no matter what version of Kernel, glibc or other system libraries had. Perhaps it has not so much sense in Windows world since the platforms are much more homogeneus. If you compile for Windows XP / NET vX.X it will work across a lot of computers. If you compile something for Debian X.X it will surely not work on older/newer Debians or other distros such as Redhat.</p> <p>This <a href="https://stackoverflow.com/questions/311882/what-do-statically-linked-and-dynamically-linked-mean">thread</a> can also solve your questions.</p>
