The install_name is supposed to be an absolute path, and use the soname rather than the developer symlink. Avoids using DYLD_FALLBACK_LIBRARY_PATH=/usr/local/lib Homebrew changes the install_name downstream, in /opt. Signed-off-by: Anders F Björklund <anders.f.bjorklund@gmail.com>

Thanks for the PR! I think that we should fix this the same way we did in Linux, by using rustc-cdylib-link-arg to pass -install_name, -current_version, and -compatibility_version.

Added the linker flags. We still need to rename and relocate the library, though. |

Reading ld's manual, I'd say compatibility_version should be MAJOR.0.0, and current_version MAJOR.MINOR.RELEASE.

The install_name is supposed to be an absolute path, and use the soname rather than the developer symlink.
Avoids using
DYLD_FALLBACK_LIBRARY_PATH=/usr/local/lib. Homebrew changes the install_name downstream, in /opt.The default is the absolute path of the build directory (not wanted)
Typical error:
