 Priority:  Normal                      |  Milestone:
Component:  ports                       |    Version:  2.7.1
 Keywords:  powerpc, ppc, leopard, gcc  |       Port:  libgcc, gcc10
----------------------------------------+---------------------------
 Now having gcc10 being able to build for ppc in Macports thanks to @catap
 efforts, a question is how to configure libgcc properly so that everything
 works.

 When I tried to build gcc10 earlier on Leopard, I faced errors with C++
 compiler: https://trac.macports.org/ticket/64577
 I am getting the same errors now with gcc10: library not found for
 -lgcc_s.1.1.

 Is it something with the way gcc10 is built or the way Macports is
 handling libgcc? gcc10-bootstrap has no problems.
