port has nomaintainer, Pete. Do you want to go ahead submit a PR adding the cxx11 portgroup, and hopefully someone will pull it for you.

No. I do not understand C++, PR, cxx11 portgroup and why macOS has become so unusable. Leopard and Snow Leopard are so fine systems, I hardly can see a reason to deviate from this. But PR, i.e. Public Relations, might be shouting: A new version comes first. And now we have the salad… (as we Germans say)

[kencu (Ken)]

Ah, OK. I will never see these kinds of errors, because all my snowleopard machines are set up properly with LibcxxOnOlderSystems. Rather than stumble across these more and more as time goes on, I would suggest you consider doing the same. The buildbots may not prebuild the software, but the time it takes your computer to build the apps yourself is peanuts compared to the time you're wasting chasing down these dinosaurs.

$ port -v installed highlight
The following ports are currently installed:
  highlight @3.35_0 (active) platform='darwin 10' archs='x86_64' date='2017-03-05T15:17:59-0800'

Incase it will help anyone esle… I managed to upgrade highlight now, using a couple of configure options.

Adding cxx_stdlib libc++ to the conf file didn't help. But I found an install note on the ​Inkscape-page: CompilingMacOsX#Compiling_with_clang_3.3_and_libc.

Just using both options to inlcude libc++ made it through.

sudo port upgrade highlight configure.cxxflags="-stdlib=libc++" configure.cxx="clang++ -stdlib=libc++"

$ port -v installed highlight
The following ports are currently installed:
  highlight @3.36_0 (active) platform='darwin 11' archs='x86_64' date='2017-04-18T06:14:46+0200'

Replying to iEFdev:

I can confirm that highlight @0.15.2_0 built with this setup on Snow Leopard, Mac OS X 10.6.8.

I confirm sudo port install highlight configure.cxxflags="-stdlib=libc++" configure.cxx="clang++ -stdlib=libc++" builds 3.36 on 10.8.

[kencu (Ken)]

Glad it worked. Couple of things, tho.

clang++ does not specify a specific compiler, and will just pull in whatever clang++ happens to be first on your path, which may or may not work. In your case, it apparently did work, though. For reliability, configure.cxx should point towards a more completely specified compiler.

Also, setting configure.cxxflags="-stdlib=libc++" will overwrite any other cxxflags there might be, which may or may not be important -- you probably would rather do a configure.cxxflags-append instead, if you're looking for a proper fix for the Portfile.

See #53994 re v3.36.
