Building problems on macOS

[louy2]

Documenting some problems I've had building this. In order of appearance.

OS: macOS Catalina 10.15.3

zsh: command not found: llvm-config

Fix: brew install llvm then export PATH="/usr/local/opt/llvm/bin:$PATH"

./vendor/xxhash/xxhash.h:663:10: fatal error: 'stdlib.h' file not found

Fix: Running xcode-select --install

benchmark.sh: line 86: declare: -A: invalid option
declare: usage: declare [-afFirtx] [-p] [name[=value] ...]

Fix: Use zsh ./benchmark.sh instead of bash ./benchmark.sh

uniq 2 huniq2-rust time: illegal option -- f
uniq 2 huniq2-rust usage: time [-lp] command.

Infinite loop.
Fix: Run brew install gnu-time then export PATH="/usr/local/opt/gnu-time/libexec/gnubin:$PATH"

Didn't wanna wait for the rest of it.

The benchmarks do take a bit of patience; glad to see the results from other platforms confirm the claims…

Regarding your issues:

1. Sure that is in the scope of this project? Seems like a general perquisite for building C code on OS X?
2. Same here.
3. Bash introduced associative arrays in version 4 – which was released 2009. How did you get your hands on a version of bash that's older than a decade? oO
4. Yeah, unfortunately the script is gnu specific at the moment. I would welcome a PR porting it to OS X!

It's a bit unfortunate, that the benchmarks are the least advanced part of huniq at the moment…I do have some plans to improve the benchmarks a lot but I haven't had the time to deal with that yet.

I've opened up a ticket on how to implement benchmarking properly, if you are interested: #8
