This was previously reported in #64711 but it was closed as invalid for some reason.

I see from your log that you have Xcode 10.1 and Apple Clang 1000.11.45.5, which are the latest version for High Sierra.

std::isnan is a C++11 feature. I see from your log that the -std=gnu++17 flag is present, so that should be sufficient.

Maybe a required header isn't being included? std::isnan is defined in <cmath>. If #include <cmath> doesn't appear in the affected source file, try adding that.

We don't see the problem on the High Sierra buildbot worker but it has Xcode 9.4.1 which I guess isn't new enough to support C++17 so the build is using MacPorts Clang 13 instead.

I didn't see an issue reported about this upstream: ​https://gitlab.com/inkscape/inkscape/-/issues; maybe someone could file one.

The previous ticket was closed, as the issue did not occur after the user re-installed MacPorts.

@ngwood, was MacPorts installed fresh on 10.13? Or did you have a pre-existing MacPorts installation from an earlier macOS release, which was then upgraded to 10.13?

Thank you for your help.

It's interesting that this problem disappeared for githubbjs after a reinstallation of MacPorts.

I believe that I originally installed MacPort on a fresh installation of macOS 10.13.6 using MacPorts-2.7.1-10.13-HighSierra.pkg. I installed Xcode via Xcode_10.1.xip and Command Line Tools via Command_Line_Tools_macOS_10.13_for_Xcode_10.1.dmg. I do recall requiring to restore from a TimeMachine backup at one point, but I do not believe that would be problematic. I can certainly try reinstalling MacPort if that is worth doing; if you would prefer I hold off doing so please let me know.

Directly including cmath in the offending file did not resolve the issue.

[kencu (Ken)]

it appears geom::Angle does not match any of the inputs accepted by std::isnan on that compiler in that mode.

So, not sure why not, perhaps a cast would fix it.

But just forcing a newer compiler might be much simpler, as that appears to work, and life is often too short to spend hours to make stuff work with relic compilers for no good reason.

[evanmiller (Evan Miller)]

You might also want to try out the inkscape-devel port. This is the Inkscape 1.2 beta version, which will graduate to a stable release soon. It's possible the issue is already fixed in there, and if not any fix will need to end up there.

[ngwood]

For completeness I did try re-installing MacPorts, but it did not resolve the issue.

[detlevd (Detlev Droege)]

Same here, with inkscape 1.1.2 as well as with v1.2.0, on High Sierra (10.13.6) with XCode 10.1. Apparrently, the compiler isn't able to derive the base type 'Coord' (aka double) and thus fails. This can be resolved by explicitly accessing the stored value, that is by changing the line in src/display/cairo-utils.cpp

                if(std::isnan(arc->initialAngle()) || std::isnan(arc->finalAngle())) {

to

                if(std::isnan(arc->initialAngle().radians0()) || std::isnan(arc->finalAngle().radians0())) {

I'll attach a diff file.

This part compiles fine now for me, but now v1.2.0 seems to have another issue in src/ui/dialog/objects.cpp where it doesn't compile a call to extract() although gnu++17 is switched on, but that's for another ticket.

Confirmed, I'm also seeing these issues on 10.13. Building with a newer version of Clang solves both, and I'll push a fix momentarily.
