#35407: unison fails with "Fatal error: Internal error: New archives are not identical" --------------------------------+------------------------------------------- Reporter: dcecchin@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.2 Keywords: | Port: unison --------------------------------+------------------------------------------- Comment(by dcecchin@…): It seems to be a problem since I reinstalled with mountain lion. It used to work just fine before that, and the official binaries work fine (I've temporarily switched over to them). It is possible it is caused by building against OCaml 4.0.0 maybe. I've tested this a number of times now deleting my ~/Library/Application\ Support/Unison/ and ~/.unison directory on the server. I suspect this break in functionality has something to do with that. -- Ticket URL: <https://trac.macports.org/ticket/35407#comment:2> MacPorts <http://www.macports.org/> Ports system for Mac OS

I guess it would have been possible to add a flag like +ocaml3 or +ocaml4 so that the user may choose which version they want to build against if ocaml3 was actually still available in macports. -- Ticket URL: <https://trac.macports.org/ticket/35407#comment:4> MacPorts <http://www.macports.org/> Ports system for Mac OS

#35407: unison fails with "Fatal error: Internal error: New archives are not identical" -------------------------+-------------------------------- Reporter: dcecchin@… | Owner: macports-tickets@… Type: defect | Status: closed Priority: Normal | Milestone: Component: ports | Version: 2.1.2 Resolution: wontfix | Keywords: Port: unison | -------------------------+-------------------------------- Comment (by macosx12345@…): 1) Since the issue is triggered by the update of ocaml from 3.x to 4.0, could we imagine a quick-and-dirty fix: increase the revision of unison to force a rebuild? (I rebuilt unison both on client and server side with ocaml 4.0 and, as others said, it solves the issue --- under Mac OS 10.6 and 10.5). This was suggested on the macports-users mailing list for the case of maxima and sbcl (everytime sbcl is updated, maxima gets broken): http://lists.macosforge.org/pipermail/macports- users/2011-November/026226.html (but, as far as I know, never put into practice for maxima, alas). Of course, there is also currently an issue with MacPorts' version of unison not being the latest stable version but an unstable version (#35116). If issue #35639 is solved, it will probably force a rebuild of unison. 2) As a side remark, if anyone wants to build unison 2.40.63 with variant x11 with ocaml 4.0: one has to rebuild first lablgtk2 with ocaml 4.0, then modify unison's Makefile.OCaml so that it looks for the labkgtk2 libraries not in OCAMLLIBDIR but in OCAMLLIBDIR/site-lib . I attach to this comment the simplest patch that works, but probably not the most robust one. -- Ticket URL: <https://trac.macports.org/ticket/35407#comment:7> MacPorts <http://www.macports.org/> Ports system for Mac OS
