Question

我正在编写一个Fortran代码，用于绘制一些数据，我遇到以下错误：

<iframe src="https://example.com" width="900" height="800" frameborder="0"></iframe>

错误来自：

Undefined symbols for architecture x86_64:
  "_hplots_", referenced from:
      _MAIN__ in ifortaBEBFS.o
      _clspak_ in ifortaBEBFS.o
      _opnpak_ in ifortaBEBFS.o
  "_number_", referenced from:
      _MAIN__ in ifortaBEBFS.o
     (maybe you meant: _for__this_image_number_or_zero)
  "_plot_", referenced from:
      _MAIN__ in ifortaBEBFS.o
      _pltline_ in ifortaBEBFS.o
ld: symbol(s) not found for architecture x86_64

我只是想用ifort或gfortran编译.f代码。

代码来自以下git存储库https://github.com/usgs/finite-fault/blob/db126a5e05dd2ca1950909ac0be9811cfe115019/src/plot/vangodshJ.f

首先，我没有使用通用映射工具，所以我必须安装它。该程序还需要两个不在同一文件夹中的其他fortran代码，因此将它们移动到同一个文件夹并按如下方式编译它解决了问题。

class Update extends Component {
constructor(props) {
    super(props);
    const { match } = this.props;
    this.state = {
        phoneNumber: match.params.phoneNumber,
        points: 0,
        error: ''
    }
}

getPoints = () => {
    firebase.auth().onAuthStateChanged((user) => {
        if(user) {
            const docRef = database.collection('users').doc(user.uid).collection('customers').doc(this.state.phoneNumber);
            docRef.get().then((doc) => {
                if (doc.exists) {
                const points = doc.data().points;
                this.setState(() => ({ points }));
                console.log(points);
                } else {
                // doc.data() will be undefined in this case
                console.log("No such document!");
                const error = 'This phone number is not registered yet...'
                this.setState(() => ({ error }));
                }
                }).catch(function(error) {
                console.log("Error getting document:", error);
                });
        } else {
            history.push('/')
        }
    });
}

componentDidMount() {
    if(this.state.phoneNumber) {
        this.getPoints();
    } else {
        return null;
    }
}

render() {
    return (
        <div>
            <div>
                <p>{this.state.phoneNumber} has {this.state.points} points...</p>
                <p>Would you like to redeem or add points?</p>
            </div>
            <div>
                <button>Redeem Points</button>
                <button>Add Points</button>
            </div>
        </div>
    );
  }
}

export default Update;

编译使用hplots的Fortran代码
