Some time ago, the computer broke down and the operating system was reinstalled. The software could not run normally, and most of them had to be reinstalled. I originally used Qt5.14.2. I thought Qt 6 was released, so I used Qt6. The database also has to be compiled and driven by itself, but Qt6 also wants to promote CMake, so my previous Qt5 method of compiling the mysql driver is not easy to use (or it can’t be used haha), Qt6 must be compiled with CMake
Prerequisites, install:
①Qt6:https://download.qt.io/archive/
②CMake:https://cmake.org/files/
③VS: https://visualstudio.microsoft.com/downloads/ (you don’t need to install it if you compile the MingW version)
④mysql:https://dev.mysql.com/downloads/installer/
Notice:
Be sure to download the source code when installing qt, otherwise the subsequent operations will not work. If you have installed qt but have not downloaded the source code, you can install the source code through the Qt maintenance tool
Start compiling the mysql driver below
First open the CMake tool, as shown in the figure
Then click Configure, as shown in the figure
Then some errors will be reported, then you need to add the Qt6 compiler path
Configure again will not report an error
Then we continue to add MySQL-related paths
First search for feature, check mysql
Then search for mysql, add the include folder in MySQL and libmysql.lib in the lib directory
Click Configure and Generate in turn
Then go to the build directory to see the generated files
At this point, the CMake part has been completed
Next, use VS to open the project in the red box below
Both Debug and Release versions of the mysql driver need to be compiled
To set the property pages
①Debug version
Compile and run directly
②Realese version
Compile and run directly
然后就可以去build目录下查看对应的驱动,将这些拷贝到Qt的MSVC编译器目录下的../plugins/sqldrivers
拷贝到MSVC编译器目录下的../plugins/sqldrivers
最后将MySQL lib中的libmysql.dll拷贝到MSVC2019编译器目录的bin目录下即可
测试
