使用 QT5 为 Android 编译 IBase 驱动程序答案

【问题标题】：Compile IBase driver for Android using QT5使用 QT5 为 Android 编译 IBase 驱动程序
【发布时间】：2022-10-06 22:01:57
【问题描述】：

几天来，我一直在尝试为 Android 编译 IBase 驱动程序。我已经有一个 Windows 桌面应用程序，我在其中编译了 IBase 驱动程序以连接到 Firebird 数据库。一切正常。

现在，我正在为 Android 编译相同的桌面应用程序。该应用程序可以正确编译并在 Android 手机上正确打开。但我需要 Android 应用程序也可以连接到远程 Firebird 数据库。这就是问题所在。我无法以任何方式生成适用于 Android 的 Ibase 驱动程序。

我的 Android 应用程序总是说：

QSqlDatabase：未加载 QIBASE 驱动程序

我已经从 Firebird 下载了许多文件来尝试生成 .so 文件。

我使用火鸟 2.5.8。我使用 Windows 10。我使用 Qt 5.14.2。

知道如何为 Android 生成 ibase 驱动程序吗？

请提供足够的代码，以便其他人可以更好地理解或重现该问题。
这不是你应该问 Qt 支持的东西吗？

【解决方案1】：

早上好。基本上，我正在编辑位于我的计算机上的项目“IBASE.PRO”C:\Qt\Qt5.14.2\5.14.2\Src\qtbase\src\plugins\sqldrivers\ibase并添加参数：

INCLUDEPATH+=C:\firebird64\include LIBS+=C:\firebird64\lib\fbclient_ms.lib

使用“Android for armeabi-v7a,arm64-v8a,x86,x86_64 (Clang Qt 5.14.2 for Android)”套件编译时，出现错误：

可能项目中包含的文件不是生成 ibase 插件的正确文件。但是在哪里可以找到正确的文件？你有任何关于使用 QT5 为 Android 编译 IBase 驱动程序的文档吗？
