若出現
Unable to open 'strcmp.S': File not found (file:///build/glibc-OTsEL5/glibc-2.27/sysdeps/x86_64/strcmp.S).
之錯誤訊息，可參考以下解法：
step 1
sudo git clone https://github.com/jeremie-koenig/glibc /opt/src/glibc
step 2
在launch.json檔案裡面 加入以下資訊
"sourceFileMap": {
"/build/glibc-OTsEL5/glibc-2.27/": "/opt/src/glibc/"
}
參考資料:
Step 1 + Step 2
sudo git clone https://github.com/jeremie-koenig/glibc /build/glibc-OTsEL5/glibc-2.27

以下附上我可以成功debug的相關設定

2019/11/23 更新
其實好像不用clone
18.04 預設放在
file /lib/x86_64-linux-gnu/libc-2.27.so
裡面
2019/12/20 更新
請到這裡
https://ftp.gnu.org/gnu/glibc/
下載 glibc
-2.27 的版本
放到/build/glibc-OTsEL5裡面
才能確保所有功能都正常
