问题描述
我在尝试使用 gfortran 编译一个简单的 fortran-90 文件时遇到一个奇怪的错误.我正在使用 macOS mojave 系统.我安装了 gfortran 8.2.0，并通过执行以下操作来检查以确保这一点:
I am getting a strange error when trying to compile a simple fortran-90 file using gfortran. I am working on a macOS mojave system. I have gfortran 8.2.0 installed and I checked to be sure of this by doing the following:
Input: gfortran --version
Output: GNU Fortran (GCC) 8.2.0

这表明 gfortran 安装正确，我也通过在终端中简单地键入:gfortran 来确认这一点，它返回:
Which indicates that gfortran installed correctly and I also confirmed this by typing simply: gfortran, into the terminal, which returns:
gfortran: fatal error: no input files
compilation terminated.
但是，当我尝试像这样编译我的文件时:
However, when I try to compile my file like so:
gfortran hello.f90 -o hello.x
我收到一个错误消息:
ld: library not found for -lSystem
collect2: error: ld returned 1 exit status
我尝试以不同的方式编译，我也尝试在 .bash_profile 中设置 LD_LIBRARY_PATH，如 https 所述://gcc.gnu.org/wiki/GFortranBinaries32Linux 但我仍然遇到同样的错误.gfortran 目录的路径名是:/usr/local/gfortran，但是在/usr/local/bin 中可以找到另一个不是目录的 gfortran
I've tried compiling in different ways and I also tried setting the LD_LIBRARY_PATH in .bash_profile as described by https://gcc.gnu.org/wiki/GFortranBinaries32Linux but I still get the same error. The gfortran directory has the pathname: /usr/local/gfortran, however another gfortran which is not a directory can be found in /usr/local/bin
输入:
which gfortran
输出:
/usr/local/bin/gfortran
以及对该目录的长列表搜索:
And a long list search of this directory:
Input: ls -l /usr/local/bin/gfortran
Output: lrwxr-xr-x 1 root wheel 32 15 May 14:07
/usr/local/bin/gfortran -> /usr/local/gfortran/bin/gfortran
如果一切似乎都正确安装，我该如何解决这个问题?
How can I fix this where everything seems to be correctly installed?
任何帮助将不胜感激！
推荐答案
我遇到了同样的问题，但是使用 homebrew 从 gcc 包安装 gfortran build 没有帮助.相反，我使用自制软件安装了整个 gcc:
I had the same problem, but installing gfortran build from the gcc package using homebrew did not help. Instead, I installed the whole gcc using homebrew:
brew install gcc
这样就解决了问题.
