can'；t使用gfortran安装此文件（mercury6_2.for）

我试过这个：

 Alan@Alan ~/mercury  
 $ gfortran -o mercury6_2.for
 gfortran.exe: fatal error: no input files; unwilling to write output files
 compilation terminated

以及：

我的文件存在：

 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

有没有其他方法可以让我做得更好？

你确定Mercury是编程语言吗？我记得它在编译的任何阶段都不需要fortran。你能给我一个指向该文件夹中README.txt的链接吗？也许这就是构建它的方式。您的第一次尝试没有成功，因为fortran命令的-o开关只指定了输出名称。也许[这个问题][1]的答案可以帮助您进一步。[1]:
