大漠插件（二、Qt使用插件时注意事项）

yayapoi~2023-11-07 11:40

本章目的

在上篇已经注册完毕大漠，那么怎么使用大漠来制作脚本，我选择了我最熟悉的Qt来开发，毕竟只是小软件，用脚本或者c++都差不了多少。本章就是开发途中的一些坑。

本人开发环境是 win11 64、Qt 5.15.2安装了5.10.0的msvc2015 32开发套件、vs2022安装了v143开发套件。

开发的坑

一 、使用32位开发套件

64位是不行的，必须使用32位开发套件 。否则会报错失败。我的32位环境就是上面的那些。

二、Qt使用ActiveX时的设置

在工程的pro文件中的 QT+= 后面加上 axcontainer，否则会报错"找不到 qaxobject.h"

三、生成dm的头文件和cpp文件

在Qt路径下，根据你的开发套件版本找 dumpcpp.exe。我装的是 5.10.0 的 msvc2015 32。所以我的路径是"C:\all\Qt\5.10.0\msvc2015\bin"。

在 dumpcpp.exe 目录下运行 cmd 。

dumpcpp.exe C:\all\freeDM3.1233\dm.dll

将路径换成你的dm.dll 路径。运行此命令后，在 dumpcpp.exe 目录下会生成 dm.h、dm.cpp 两个文件。我们开发时就需要使用这两个文件。

四、C3615 constexpr 函数"qCountLeadingZeroBits"不能生成常量表达式

我们需要修改 qalgorithms.h 。 此处参考了别人的文章。

因为我用的是 Qt 的msvc2015 开发套件，所以我的路径是 "C:\all\Qt\5.10.0\msvc2015\include\QtCore "。在这里找到 qalgorithms.h。

加入两行代码，修改四处即可。

不管是debug 还是 release 。都能成功运行。运行后打印

这就代表大漠已经成功调通，接下来就可以正常开发了
