Boost C++ Libraries

Macro BOOST_TEST_DYN_LINK (which instructs the compiler/linker to dynamically link against a shared library variant) may be implicitly defined when macro BOOST_ALL_DYN_LINK is defined.

In order to be able to run a test built with the dynamic variant, the operating system should be able to find the dynamic library of the Unit Test Framework. This means, for example on Linux and MacOSX respectively, setting the environment variable LD_LIBRARY_PATH or DYLD_LIBRARY_PATH properly prior to the execution of the test module.
