HDF5 C ++ Qt冲突声明

Question

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

我所做的：我创建了一个新的项目在做什么，但加入hdf5.lib作为外部库的hdf5_test.pro使用Qt的向导做这件事和#include <hdf5.h>在mainwindow.h

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

---

使用方法：

• 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 # The following define makes your compiler emit warnings if you use # any feature of Qt which has been marked as deprecated (the exact warnings # depend on your compiler).

这可能是一个类似的问题，但是没有答案。

Answer 1

这是一个入侵，但对于hdf5.h检查H5_SIZEOF_SSIZE_T为等于零。 所以用

#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。
