I can't build this graphviz with a new install of OS X 10.15.6, Xcode 11.6. Have sudo port deactivate active; sudo port install -Nv graphviz build.jobs=1. My /opt/local/etc/macports/variants.conf has +no_x11 -x11 +quartz -universal.

Will attach log of failed install.

The error you are seeing is different:

error: no member named 'min' in namespace 'std::__1'

Different errors should be in different tickets since they may need different solutions.

Ok sorry, created #60962.

I'm still not sure what the not a C compiler: should compile 'int i = 1;' error is about. Apparently something called "iffe" is trying to use the C compiler to compile a simple program and it is failing, but I don't know what "iffe" is and the log doesn't seem to be showing us what error message the C compiler emitted, so I don't know how to diagnose this. I don't think anyone else is experiencing this.

You might try reinstalling a version of Xcode compatible with your macOS version and the matching version of the command line tools to ensure that you have a working compiler.

iffe was a quirky home grown config utility in the Graphviz build. It was removed in ​Graphviz commit 1a8df410a7469d962dc79c2c99846fb681e84a06, that made it into Graphviz release 2.46.0. Pulling the latest version of Graphviz into Macports should likely resolve this.

Graphviz is at 2.49.1 now.

Then presumably this error cannot happen anymore.
