编译报错

[wangdemon]

1 QtCreator编译，使用msvc模式编译，没有问题

2 QtCreator编译，使用mingw编译，一堆错误(Qt5.15.2版本)

• 错误1 查看提示查看日志文件，没有看懂，错误类型是什么

这是提示的日志文件 qmsetup_build-Release.log

• 错误2 所有qm开头的cmake指令都不识别

Qt5.15.2版本的Mingw是8.1版本，不兼容qmsetup子模块

必须把所有子模块都克隆下来，如果你直接下载的zip包或者clone时没有加--recursive参数，都会导致子模块遗漏

Qt5.15.2版本的Mingw是8.1版本，不兼容qmsetup子模块

如何不兼容？报什么错？

加了--recursive参数

msv模式编译，是可以成功编译的

只是在mingw模式编译失败

我也遇到了同样的编译问题（Qt5.15.2）。 1 QtCreator + msvc模式编译通过 2 QtCreator+mingw编译失败，错误提示及日志，和[wangdemon]反馈的一致。

根据stackoverflow的信息，貌似都是让你升级mingw到至少v9

MinGW 8.1 对 C++17 的支持有限，尤其是 filesystem 支持不完全，所以建议升级到 9 以上。README 里写了只在 MinGW 13 中测试过没问题。
