Help about the --backend flag.

## NAME

dlv-backend - Help about the --backend flag.

## SYNOPSIS

**dlv backend \[flags\]**

## DESCRIPTION

The --backend flag specifies which backend should be used, possible values are:

```
default		Uses lldb on macOS, native everywhere else.
native		Native backend.
lldb		Uses lldb-server or debugserver.
rr		Uses mozilla rr (https://github.com/mozilla/rr).
```

Some backends can be configured using environment variables:

- •

  DELVE\_DEBUGSERVER\_PATH specifies the path of the debugserver executable for the lldb backend

- •

  DELVE\_RR\_RECORD\_FLAGS specifies additional flags used when calling 'rr record'

- •
