Unreal Engine 4でのmake時でxlocale.hファイルが見つからないエラー

Question

こんにちは。

自動運転のシミュレータCARLAを動かそうと思い、以下のURL：自動運転シミュレータのCARLAを動かす（　https://vaaaaaanquish.hatenablog.com/entry/2018/01/09/223003　）にしたがって設定を行っていました。

しかし、Unreal Engine 4のインストールの手順にあるmakeの時にエラーが出てしまいます。
エラー時の実行結果

xlocale.h file not foundというエラーが表示され、

make
のコマンドを打った際にも同じようなエラーが表示されました。

修正方法の検討がつきません。
解答してくださると幸いです。よろしくお願いします。

Answer 1

ln -s /usr/include/locale.h /usr/include/xlocale.h
を用いてシンボリックリンクを作成したら実行できました。
