#46801: ld64 @2 +ld64_127 : Wrong default for G4 Leopard
-----------------------------------+--------------------------------
 Reporter:  zanderpower@…          |      Owner:  macports-tickets@…
     Type:  defect                 |     Status:  new
 Priority:  Normal                 |  Milestone:
Component:  ports                  |    Version:  2.3.3
 Keywords:  PPC G4 Leopard libgcc  |       Port:  ld64
-----------------------------------+--------------------------------
 The default choice for '''OS X 10.5.8''', at least on 32-bit G4's, is
 '''ld64 +ld64_127'''.  Out of the box, '''libgcc @4.9.2_1''' will not
 build using this variant.

 You might try adjusting the defaults for various particular platforms and
 OS versions (for all I know, '''ld64 +ld64_127''' may work on a 64-bit
 G5).

 While posting to an open ticket for libgcc, I noticed other people are
 having the same problem: [https://trac.macports.org/ticket/46557] and
 [https://trac.macports.org/ticket/45174]. These failures might also be
 confounded with a recurring '''libgcc bootstrap regression issue''' (see
 [https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63703]).

 '''NB''': I am in the middle of rebuilding MacPorts from scratch after the
 registry became corrupted, prior to the failure of my PowerBook's DC-power
 logic board, for which I waited two weeks for a replacement. After the
 '''libgcc @4.9.2_1''' build failed, I tried compiling '''libgcc
 @4.9.1_1''', which worked back in November--again, failure. Then,
 following a vague suspicion that the root lay in the new division of
 '''ld64''', I installed '''ld64 +ld64_97''' and tried a third time--
 finally success. The failed attempts both boinked near the end of the
 build--over 6 hours on a PowerBook G4 @1.67 GHz. So I enjoyed an entire
 day of head-scratching and teeth-gnashing, all with little hope of
 success.

 (Sorry, I needed to vent.) '''''I realize you are a volunteer, and I
 sincerely thank you for your effort.'''''

 '''ld64_97''''s log unfortunately clobbered '''ld64-127''''s log, which
 consisted ''mostly'' of warnings, even though '''ld64-127''' installed
 without so much as a burp. So below are logs of '''libgcc''''s failed and
 successful builds. I will also post them here:
 [https://trac.macports.org/ticket/46557].
