在调试模式下编译时，我的应用程序的启动和操作是可能的和成功的。此外，发布模式下的构建不会给出任何错误。

我专注于：
mingw32-make[1]: Nothing to be done for 'first'.
它是什么，它有什么作用？
但是当我运行(伪(构建的应用程序时，我得到：
21:25:57: Starting C:Users**Desktop**2BattleShipsbuild-B-Desktop_Qt_5_12_7_MinGW_64_bit-ReleasereleaseB.exe ...
21:25:57: The process was ended forcefully.
21:25:57: C:Users**Desktop**2BattleShipsbuild-B-Desktop_Qt_5_12_7_MinGW_64_bit-ReleasereleaseB.exe crashed.
当我尝试从资源管理器手动运行构建的应用程序时，我收到典型的链接错误(好像使用了库的动态链接(
Qt5core.dll can not be found
另一个是关于缺乏一些 GCC 库。
我想我的 .pro 文件有问题。 是这样的：
static {
CONFIG += static
QT += core gui network widgets
DEFINES += STATIC
message("Static build.")
}
CONFIG += static -std=c++2a
# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the

DEFINES += QT_DEPRECATED_WARNINGS
# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.

如何正确构建和启动此应用程序的任何建议？
两件事：Qt文件需要在PATH中，Qt必须能够找到它的插件。
您可以启动命令提示符并运行以下命令：
SET PATH=<qt_path>bin:$PATH
SET QT_PLUGIN_PATH=<qt_path>plugins
，然后从同一命令提示符运行已编译.exe。
