<![CDATA[QtMqtt deployment Failed]]>I tried to use Mqtt to communicate in the project. So I downloaded the 5.14.2 version of mqtt from https://github.com/qt/qtmqtt. I encountered the following problems during the compilation process:
1：

2.For the above problem, I put Mqtt in the mqtt source directory under the Qt installation directory, it can be solved, and the compilation can be completed normally.
3.Then I tried to deploy mqtt to the Qt installation directory. The specific process is shown in this link: https://www.pianshen.com/article/74801067784/

4.I created a new project, QT+=mqtt in the .pro file, and #include<QtMqtt/QtMqtt> in the c++ file, and the following error occurred when compiling
e6531dc0-9561-429b-a94e-d63952a09f8a-image.png
5.The mqtt module almost crashed me. I asked someone to analyze the reason. It looks like 6 when compiling normally.

6.8493f31c-dcbe-4bcb-9b18-10093279dae4-image.png

7.The abnormal compilation is shown in 7, can you help me? I'm about to break down

As I said before, the log you are showing here looks like a build on top of an already attempted build rather than one from scratch (which means completely nuking the build folder). The "nothing to be done" typically appears when there's already been a build (successful or not) done.

Hence I am asking you to do a full clean rebuild which means completely removing the build folders before hitting the build button. You should have a message near the start of the build process stating that the forward headers are being generated if they are not then you likely have an issue with pearl.

Which version of Perl are you using ?
From the looks of it, it's not the log of a complete full rebuild.
perl version is 5.22.1

He did not complete the compilation, mingw32-make[2]: Nothing to be done for'qmake_all' will appear.

Check any output that shows error when configuring/starting the build.

t源，因此您可能会在系统上缺少标头生成部分的Perl，这可能解释了模块构建失败的原因。
I already have perl installed on my computer. How can I solve this problem?

Since you are using git sources you are likely missing Perl on your system for the header generation part which would explain why your build of the module failed.
