GLFW - 多くのエラーはこのコードです

Question

私の大学の講師は私たちにこのコードを教えてくれました。それは決してありません。それは決してありません。これまでに働くことはできませんでした。私たちの講師は私たちに壊れた材料を与えてくれましたか私は真剣にこれを理解することはできませんし、助けが必要です、私は多くのミスを修正することができましたが、その後、この問題は '100％働いている'というコードにもかかわらず解決するのが難しくなりました....サイドノート：すべてのディレクトリが正しくフォーマットされ、追加の依存関係が私の知る限り正しく設定されています。

実際のコードが2行に分割されていないコードが複数あるため、コードはコメントと同じ行にあり、実行されません。これは適切な行末のプログラムです：
