Problem Solving Process of The terminal process terminated with exit code 1

參考前輩的配置VScode C/C++環境的經驗：

參考之後我的配置

出現的問題

collect2.exe: error: ld returned 1 exit status
The terminal process terminated with exit code: 1

也看到Stack Overflow上有類似問題

分析問題

因爲看不懂報錯信息，只能暴力檢索。
Keyword:

The terminal process terminated with exit code: 1
or
undefined reference to `WinMain@16’

Result: 有個前輩說他環境變量配置不正確
and
Something probably useful from it

Project -> properties -> build targets -> Type set it to native or gui…
If it doesn’t work (I’m not a windows user anymore) search the forum for sollutions…

I made it working. It was because there was not created main script, so the main function was missing.

解決辦法

我檢查了一下自己配置的環境變量，的確有問題。

That 's all and I must be careful next time…
