@sls1005 The way you do this is to add code to determine if there is a new definition and then get it. That's a great technique !
@elcritch In the test, I confirmed that if I put "when defined(nuttx):" around the recv() called in selectInto() of ioselectors_select so that recv() is not used, it works without network. However, I don't want to make the beautifully written code dirty, so I decided to enable local loopback. After all, without some kind of network interface, it is not possible to communicate with the outside world (usually, PPP is used with LTE). However, I should have used "select" as initially advised. I was testing on a machine with 512 MiB of memory that dual-boots with Linux, so I didn't realize how much memory the EPOLL implementation would require.
