我试过了：
Alan@Alan ~/mercury
$ gfortran -o mercury6_2.for
gfortran.exe: fatal error: no input files; unwilling to write output files
compilation terminated
和
Alan@Alan ~/mercury
$ gfortran -o mercury mercury6_2.for
gfortran.exe: error: CreateProcess: No such file or directory
我的档案存在：
Alan@Alan ~/mercury
$ ls
big.in element.in mercury.inc mercury6_2.for README.txt
close.in element6.for mercury6.man message.in small.in
close6.for files.in mercury6.tar param.in swift.incenter code here
gfortran似乎在Cygwin中运行：
Alan@Alan ~/mercury
$ gfortran --version

所以我不知道。
我能以不同的方式做到这一点吗？
