a full path or a partial path to a dylib),Дlopen() searches the following until it finds a compatible Mach-O file: $DYLD_LIBRARY_PATH (with leaf When path contains a slash but is not a framework path (i.e. The OS X dlopen documentation ( ) specifies that when providing an absolute path, it will first look in locations specified by DYLD_LIBRARY_PATH: In general, when libraries are installed to non-standard locations absolute paths should be specified which negates the ambiguity of the dynamic lookup.ДYLD_LIBRARY_PATH does not behave like LD_LIBRARY_PATH.

The benefit is that this process will not cause symbol lookup errors in applications compiled against the default libraries. This will look for symbols in libraries provided in the default paths and if the symbol is not found there, fall back to the specified path. When installing libraries to a non-standard location, DYLD_FALLBACK_LIBRARY_PATH is much more sane. This is due to the system blas/lapack not being a full implementation of the ATLAS libs.ДYLD_FALLBACK_LIBRARY_PATH will not produce these problems. This will cause symbol not found errors in applications linked to the system VecLib if DYLD_LIBRARY_PATH is set and the reverse (symbol lookup errors in custom applications) if it is not.

A good example of this is when you attempt to override the default install of VecLib (e.g.

In general, these are (both on osx and linux) suggested only for development use as they can cause symbol lookup errors when you override with a library that does not have the same symbol table. However, there is another environment variable you should look at called DYLD_FALLBACK_LIBRARY_PATH. As you've noted, DYLD_LIBRARY_PATH behaves like LD_LIBRARY_PATH on other *nix.
