Errors when compiling on macOS

[bdcarr]

Hullo, I'm following the instructions for compiling on macOS 10.15.6 and it's failing with four errors.

I think this is the relevant system info:

❯ gcc --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.3 (clang-1103.0.32.59)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Here's the build output (only showing the errors I guess because the rest is cached from previous attempts):

❯ make -f Makefile.cocoa install

In an odd coincidence, I think I posted the same issue today, but when I figured it out, I closed it. Basically, you need to compile using master, vs. the 1.4.2 release.

Ha, that'd be right! I searched for similar issues yesterday but didn't bother posting until just now. Thanks mate, hopefully this prerelease version isn't too unstable 🤞
