HDF5 C++ Qt 冲突声明

Question

情况：我需要读取一个.hdf5文件，并在使用Qt创建的界面中以图形方式显示数据。

我做了什么：我创建了一个新项目，只是使用 qt 向导将hdf5.lib作为外部库添加到hdf5_test.pro中，并在mainwindow.h中#include <hdf5.h>

问题：尝试运行代码时，出现此错误：conflicting declaration 'typedef long long ssize_t'

用：

• C++
• Qt 5.10.1
• MinGW 5.3.0 32位C++
• HDF5 1.10.2

---

我的代码：

#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
#include <hdf5.h>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private:
Ui::MainWindow *ui;
};
#endif // MAINWINDOW_H

QT       += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = hdf5_test
TEMPLATE = app

这可能是一个类似的问题，但没有答案。

Answer 1

这是一个黑客，但hdf5.h检查H5_SIZEOF_SSIZE_T是否等于零。所以使用

#define H5_SIZEOF_SSIZE_T H5_SIZEOF_LONG_LONG

在包含HDF5.h之前，可以通过不重新定义类型来提供帮助。
