Orientation techniques in general. • Today, we give extra attention to “relocatability” ## Relocatability: - Does NOT refer to relocatability as what it means talking about “Position Independent Code”, relocation misses, IMO his results are representative of what would be real world use. ## Advantages of Relocatability • From Data Orientation: - The predictability and control of where the data will reside: where slots in the arrays of their components: Slow down the performance of the remaining entities. • Relocatability allows you to “defrag” the arrays. - New entities are added to the place of old, removed entities:

executable or library - The $ORIGIN keyword: the directory containing the executable (allows for relocatability) ●●●● $ LD_DEBUG=libs ./my_program 255: find library=libfoo.so [0]; searching 255: search

binaries that are coded with library locations, and this information must sometimes be replaced for relocatability, but Windows does not generally embed prefixes in binaries, and was already relocatable. We skip

target prefix. Ummm… what? Why would conda modify a file to install it? This has to do with relocatability. When a conda package is created, conda-build creates up to three temporary environments: •
