`ninja all check-all`
Install `i2prouter`, start it (`i2prouter start`) , start the SAM bridge (can be done in a browser http://127.0.0.1:7657/configclients), then run:
```
ninja && src/bitcoind -regtest -i2psam=127.0.0.1:7656 -debug=i2p
```
At this point, it still does not do much, but the new command line options are accepted.
