| Summary | 0005105: Regression: changes to disable natdynlink for 32-bit OSX also disable using shared libraries |
| Description | 3.11 on 32-bit OSX could use shared libraries perfectly well (e.g., programs compiled with ocamlc did not need the runtime+libraries linked with them). I understand why natdynlink has been disabled for 3.12.0+beta1, but those changes in the `configure` script have also disabled using shared libraries.
After patching `configure` to allow shared libraries and disallow natdynlink with the attached patch, I have found no problems. As long as the libraries don't contain non-PIC code (like that generated by ocamlopt :), there shouldn't be any. This is with a Core Duo Macbook with 10.6 (which is 32-bit only).
[In particular, note that linking with shared libraries doesn't need the "-read_only_relocs suppress" that natdynlink requires (and is no longer supported by Apple's ld).] |
