gcc10-bootstrap fails to build on Tiger PPC: Undefined symbols: "__Unwind_fallback_frame_state_for"

[kencu (Ken)]

gcc10-bootstrap is an essential step towards having all the systems default to libgcc12 (and newer), however it does not build on PPC Tiger, at least. So the upgrade to libgcc12 is on hold pending resolution of this issue.

Ken, may I ask you to test this patch? Thanks.

[kencu (Ken)]

building ...

[kencu (Ken)]

unfortunately, same error. Patch confirmed to be applied. new log uploaded.

[catap (Kirill A. Korinsky)]

Ken, I've backported Ians patch that should fix this issue: ​https://raw.githubusercontent.com/catap/macports-ports/ca3e696743b673bb93d6687d63798e3d9e93b612/lang/gcc10-bootstrap/files/patch-darwin8.diff

May I ask you to test it? It should be applied without tiger-ppc.diff​

[kencu (Ken)]

successfully patched and building again ...

[kencu (Ken)]

yep, that last patch fixed gcc10-bootstrap on 10.4 PPC.
