Dynamic linker notesEdit

Seeing which dynamic libraries get loaded

$ export DYLD_PRINT_LIBRARIES=1
$ ls
dyld: loaded: /bin/ls
dyld: loaded: /usr/lib/libncurses.5.4.dylib, cpu-sub-type: 3
dyld: loaded: /usr/lib/libgcc_s.1.dylib, cpu-sub-type: 3
dyld: loaded: /usr/lib/libSystem.B.dylib, cpu-sub-type: 3
dyld: loaded: /usr/lib/system/libmathCommon.A.dylib, cpu-sub-type: 3
$ unset DYLD_PRINT_LIBRARIES

Inserting a dynamically loaded framework

$ export DYLD_INSERT_LIBRARIES="/full-path-to/Framework.framework/Framework"

Multiple libraries can be specified, each pair separated by colon. It appears that libraries are inserted in the same order in which they appear in the specification.
