Do you have the compiler installed? 'functional' is a standard C++ header - even in C++98. Maybe you need the -dev package - I don't know what system the Mac uses, but Linuxes use -dev versions of packages, for the headers (though really, you can't compile without headers so I wouldn't expect that you'd need them. But obviously something is wrong).

Also, I've not set this up to be built as a wheel. I need to, but it's waaay on my back-burner.

I am running into the same issue on a new Mojave machine I'm trying to install this package to.

I can confirm that I do have the compiler installed (I installed xcode and command line tools) and yet I'm running into that exact same issue. I'll keep poking around but any hints would be greatly appreciated here.

Edit: The suggestion on this comment here worked for me.

MACOSX_DEPLOYMENT_TARGET=10.13 pip install noaho

[Spikhalskiy]

If NoAho installed using conda, conda respects MACOSX_DEPLOYMENT_TARGET system environment variable, so you can do:

export MACOSX_DEPLOYMENT_TARGET=10.13
conda env create -f conda-env.yml
