Questions tagged [dynamic-library]

Compiled binaries capable to be loaded in the process address space in runtime.

Dynamic Libraries are compiled binaries capable of being loaded/unloaded into/from the process address space at runtime.

In the Unix world, they are called shared libraies; in the Windows world, they are known as DLLs (dynamically-loadable libraries).

They can be loaded simultaneously into multiple processes, saving RAM and disk space.

Their file format is similar to, or even the same as, that of binary executables.

Setting LD_LIBRARY_PATH environment variable for loading a shared library at runtime (g++)

I'm having two problems related to the same issue: I have a shared object saved in `pwd`/lib and while the executable that uses it compiles successfully (by using -l and -L switches), at runtime, it's giving me grief. If I try to run…

Multiplatform way to determine if a dynamic library is present

I need to check if a dynamic library is present, so that later I can safely call functions that use this library. Is there a multiplatform way to check this? I am targeting MS Windows 7 (VC++11) and Linux (g++).
