Debug Compiler

首先构建一个可debug的版本

1
bazel build -c dbg --spawn_strategy=standalone //source/exe:envoy-static

生成 dSYM

进入到 envoy-static 同级目录，执行：

1
dsymutil envoy-static -o envoy-static.dSYM

Debug

Debug By LLDB

$ lldb envoy-static
(lldb) process launch --stop-at-entry -- -c $PATH_TO_CONFIG
(lldb) add-dsym envoy-static.dSYM
(lldb) breakpoint set --file server.cc --line 147
(lldb) continue

Debug By Vscode

open launch.json file and change program to “${workspaceFolder}/bazel-bin/envoy” (lauch.json will open when to start debugging)

    ]
}

Debug in Clion

Gen CMakeList

下载 bazel-cmakelists，在envoy目录下运行，生成 CMakeLists.txt。

1
./bazel-cmakelists --targets //source/exe:envoy-static --skip_build
