Eu estou tentando compilar algum código-fonte, no entanto, quando eu digito o comando "make" no terminal, ele produz um erro. Do meu entendimento limitado, o problema parece surgir quando o código tenta produzir arquivos .f90 a partir dos arquivos .F. A partir da leitura na web, parece que o problema pode estar relacionado com o pré-processador. Parece que um cabeçalho c está sendo adicionado aos arquivos .f90 com os quais o gfortran está tendo um problema. A saída após o comando "make" é a seguinte:
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.

Eu sou novo no Linux e não tenho nenhum conhecimento real de C ou FORTRAN, então peço desculpas se a pergunta for tola.
O arquivo de saída (neste caso, mod_prec.f90) contém o seguinte cabeçalho, que é a causa do erro devido ao comentário estar no formato C:
