Eugene Kim	ed7a62ebab	Use a rough equivalent of realpath ... realpath(1) is not available on macOS. (Funny, because realpath(3) originated in FreeBSD, so it came to macOS before Linux adopted it, but Linux beat macOS to realpath(1).)	6 years ago

Eugene Kim	bd0f4401de	DYLD_LIBRARY_PATH → DYLD_FALLBACK_LIBRARY_PATH ... DYLD_LIBRARY_PATH has a “look here first before usual places” semantics, in order to let users use an alternative version of a shared library. On the other side, DYLD_FALLBACK_LIBRARY_PATH has a “look here if not found in usual places” semantics, in order to let users specify additional locations where a shared library is found. In our case, if a binary refers to a common shared library found in usual places, we want to use it; we simply want to specify additional locations where BLS/MCL/OpenSSL libraries are found. So it is more appropriate to use DYLD_FALLBACK_LIBRARY_PATH. This also fixes a nasty symbol table mismatch, which is the main reason for this change: Certain commonly used shared libraries - such as libJPEG.dylib, co-located within the ImageIO framework and expected by the main ImageIO library – are often also found in Homebrew or MacPorts root (/opt/local//lib for MacPort). If DYLD_LIBRARY_PATH included /opt/local/lib for OpenSSL, many system programs linked against ImageIO will erroneously pick up libJPEG.dylib in /opt/local/lib, which lacks certain internal symbols that the framework version has. Using DYLD_FALLBACK_LIBRARY_PATH makes dyld honor the full path to the framework version of libJPEG, which is hardcoded in the main ImageIO framework library.	6 years ago
