Qt5 - Windows :Windows 找不到可执行文件

Qt5 - Windows :Windows cannot find executable

我正在尝试使用 Windows 10Qt5.12 构建项目。小程序正在使用可用的 smtp 协议 here。我可以确认,在我的 Windows 上,我有 2019 年 5 月 28 日的 OpenSSL 1.1.1c。在我的 Ubuntu 19.04 上,完全相同的程序编译和 运行 像往常一样,但在 Windows.

git clone 我的存储库进入 Windows,成功 并且程序构建正确。

问题 是当我 运行 它时,它 cannot find the executable 并且正在请求它,因为可以从下面的打印屏幕中看到:

这是我的 .pro 文件:

QT += quick quickcontrols2 concurrent network core gui

CONFIG += c++11

# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Refer to the documentation for the

DEFINES += QT_DEPRECATED_WARNINGS

TARGET = SMTPEmail
DEFINES += SMTP_BUILD

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

在我的桌面上,它自动创建了 build 文件夹,并认为可执行文件会在这里。下面我还附上了 build 文件夹内内容的打印屏幕:

最初这个项目是在 Ubuntu 上部署的,这没有给我带来任何问题。我 git clone 那个 repo 到我的 Windows,添加了丢失的 SMTP_BUILD 但我无法确定打印屏幕中 window 要求的可执行文件。这最后一步我错过了什么?

非常感谢您指出正确的方向。

如您的 .pro 图像所示,您正在使用 TEMPLATE = lib,其 objective 用于创建一个库,其产品是 .dll、.so 等,而不是 . exe.

如果要生成可执行文件,您必须使用:

TEMPLATE = app

加上:

为了更容易将库包含在您的项目中,我创建了 this project,其 objective 是为了提供一个 .pri,它很容易 link 到任何项目.pro.为此,您必须遵循以下步骤:

  • 下载项目
  • include(/path/of/SMTPEmail.pri) 添加到您的 .pro
  • 包括使用 #include <SmtpMime>
