一部のソースコードをコンパイルしようとしていますが、端末に「make」コマンドを入力するとエラーが発生します。限られた理解によると、コードが.Fファイルから.f90ファイルを生成しようとすると問題が発生するようです。オンラインで読むと、問題はcプリプロセッサに関連しているようです。 acヘッダーが.f90ファイルに追加され、gfortranに問題があるようです。 「make」コマンドの出力は次のとおりです。

make: Circular mod_prec.o <- mod_prec.o dependency dropped.
make: Circular mod_prec.o <- mod_prec.o dependency dropped.

make: Circular mod_prec.o <- mod_prec.o dependency dropped.

私はLinuxに初めて触れており、CやFORTRANについての実際の知識がないので、この質問が愚かだと申し訳ありません。

出力ファイル（この場合はmod_prec.f90）には次のヘッダーが含まれていますが、これはコメントがC形式であるためエラーが発生する理由です。
