30afcc07 | 207 | # For Darwin AKA Mac OS/X (dyld) |
e048fd51 | 208 | # Originally link_dso.darwin produced .so, because it was hard-coded |
cad6650f AP |
209 | # in dso_dlfcn module. At later point dso_dlfcn switched to .dylib |
210 | # extension in order to allow for run-time linking with vendor- | |
e048fd51 | 211 | # supplied shared libraries such as libz, so that link_dso.darwin had |
cad6650f AP |
212 | # to be harmonized with it. This caused minor controversy, because |
213 | # it was believed that dlopen can't be used to dynamically load | |
214 | # .dylib-s, only so called bundle modules (ones linked with -bundle | |
215 | # flag). The belief seems to be originating from pre-10.4 release, | |
216 | # where dlfcn functionality was emulated by dlcompat add-on. In | |
217 | # 10.4 dlopen was rewritten as native part of dyld and is documented | |
218 | # to be capable of loading both dynamic libraries and bundles. In | |
219 | # order to provide compatibility with pre-10.4 dlopen, modules are | |
220 | # linked with -bundle flag, which makes .dylib extension misleading. | |
221 | # It works, because dlopen is [and always was] extension-agnostic. | |
75db4b2f AP |
222 | # Alternative to this heuristic approach is to develop specific |
223 | # MacOS X dso module relying on whichever "native" dyld interface. | |
