Main.log from High Sierra 10.13.6

[ryandesign (Ryan Carsten Schmidt)]

Ok, because you've selected the +fltk variant, it builds things that require the fltk library, but it has failed to link with that library, therefore the symbols that would have been found in that library are not found.

I can reproduce it on macOS 12.

Bugs get reported here: ​https://pari.math.u-bordeaux.fr/Bugs/

[wbl (Watson Ladd)]

I'll look into it this weekend or next.

Does this happen with building from source? Might just be a small adjustment to the portfile needed.

[ballapete (Peter "Pete" Dyballa)]

Replying to wbl:

Yes, I built from Portfile.

[wbl (Watson Ladd)]

Sorry, i meant building without benefit of macports.

My guess is I need to tweak and tell the linker where we put fltk.

[wbl (Watson Ladd)]

I've been able to reproduce finally. Will work more on this this weekend: I expect once I get into it it should be a few small tweeks to the link command.
