无法制作qmqtt

问题描述 投票：1回答：1

我以前安装过qt4。现在，我已经安装了QT5.7。我正在尝试编译qmqtt项目以生成libqmqtt文件。 Qmake很好。但是make出现以下错误。

花了很多时间。通过Qt 5.7.0编译后，文件夹“ release”中没有Dll文件。我查看编译日志，发现在项目的磁盘根目录中创建了文件夹“ lib”，在其中找到了Dll。但是使用DLL可以使您在Windows上工作。我需要在Android上使用。

在github中，有人建议将其用作纯代码。

我将其重写为“普通代码”，并创建了示例项目。 It is here。有两个文件夹：project和mosquitto，用于在localhost上使用mqtt
