Binaries are available for multiple distributions and operative systems, but you can also build the miner by yourself. Take a loot at [XMrig's docs](https://xmrig.com/docs/miner)
Most pools are <abbr title="Pay Per Last N Shares">PPLNS</abbr> pools, which means that you only get paid when a miner on the pool finds a block. If the pool you are mining on is small, this can take a few days to weeks.
