## LLGo Plugin of LLDB
|
||||
|
||||
### Build with debug info
|
||||
|
||||
```shell
|
||||
llgo build -o cl/_testdata/debug/out -dbg ./cl/_testdata/debug
|
||||
```
|
||||
|
||||
### Debug with lldb
|
||||
|
||||
```shell
|
||||
lldb -O "command script import _lldb/llgo_plugin.py" ./cl/_testdata/debug/out
|
||||
```
|
||||
|
||||
```lldb
|
||||
/opt/homebrew/bin/lldb -O "command script import _lldb/llgo_plugin.py" ./cl/_testdata/debug/out
|
||||
Breakpoint 1: no locations (pending).
|
||||
Breakpoint set in dummy target, will get copied into future targets.
