I uninstalled inkscape and all its leaf ports and then attempted to reinstall it, yet the health of the port is green for my systems (High Sierra and Mojave).

main log inkscape build

[reneeotten (Renee Otten)]

not sure, but isn't std:optional only valid in C++17; if so it's probably not using a new enough compiler on these old(er) systems.

[mf2k (Frank Schima)]

I'm seeing this on Monterey.

[JDLH (Jim DeLaHunt)]

I am seeing this on macOS 10.14.6 Mojave, with clang 11.0.0 and MacOS 10.15 SDK:

That's right. Looks like poppler is now requiring its dependents to build as C++17. That's a bit of extra pain here because inkscape seems to be explicitly adding -std=c++11.

[mascguy (Christopher Nielsen)]

Given that this port is very out-of-date relative to upstream - and I'm not sure when we'll get around to updating it - I'd suggest installing the binary distribution from inkscape.org for now.

[mascguy (Christopher Nielsen)]

@dbevans, if you'd be interested in getting this updated and working, I'd appreciate it.

I've taken on a boatload of GNOME/GIMP-related components in your absence, enough so that my backlog has gotten completely overwhelming.

[evanmiller (Evan Miller)]

Researching this a little bit, requiring C++17 (and setting configure.cxxflags -std=c++17) results in other build errors, due to standard library features being removed between C++11 and C++17. So getting Inkscape 0.92.5 and Poppler 22.0.x to play together may require non-trivial patching.

[rufty (Bill Hill)]

Seen on High Sierra 10.13.6

[eric-j-ason]

Is there a reason that we're using Inkscape 0.92 here, instead of a more recent version?

[mascguy (Christopher Nielsen)]

Replying to eric-j-ason:

That's simply because we haven't gotten around to updating it yet. Please see issue:61404.
