you’ll see this error many times on Tiger in various ports.

sys/signal.h changed quite a bit between Tiger and Leopard, and has stayed stable since.

Many Tiger builds would work better if you could use the 10.5 SDK to build things on Tiger, but there are problems doing that nobody ever sorted out.

The kinds of fixes needed can be seen in this patch by Evan

​https://github.com/macports/macports-ports/blob/master/lang/ruby22/files/patch-ruby22-tigeri386.diff

Or see what Jeremy did in the ld64 portfile.

You do learn a great deal about MacOS building by fixing Tiger errors, though. Touches many things.

Is it possible to fix these somehow via legacysupport? It is unrealistic to patch every affected port manually (unrealistic in a sense none of us gonna bother doing that).

sure, it's possible you could sort something like that out for legacysupport.

Ken, could you perhaps close this as a duplicate of #67248

16. S. And maybe add Kirill @catap and @evanmiller to CC in that ticket, I cannot edit that field from my end.
