Qt5 - Windows :Windows cannot find executable

问题

I am trying to build a project using Windows 10 and Qt5.12. The small program is using the smtp protocol available here. I can confirm that on my Windows I have the OpenSSL 1.1.1c 28 May 2019. On my Ubuntu 19.04 the same exact program compiles and run as usual but not on Windows.

I git clone my repository into Windows, followed successfully this post and the program builds correctly.

The problem is that when I run it, it cannot find the executable and is asking for it as it is possible to see from the print screen below:

here is my .pro file:

QT += quick quickcontrols2 concurrent network core gui

CONFIG += c++11

# 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). Refer to the documentation for the
# deprecated API to know how to port your code away from it.
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

On my Desktop it is created automatically the build folder and thought that the executable would have been here. Below I Am also attaching a print screen of what is inside the build folder:

Originally this project was deployed on Ubuntu and that gave me no problem. I git clone that repo into my Windows, added the missing SMTP_BUILD but I can't fine the executable that the window in the print screen is asking. What am I missing for this final step?

Thank you very much for pointing in the right direction.

回答1:

As shown in the image of your .pro you are using TEMPLATE = lib whose objective is to create a library whose product is a .dll, .so, etc. that is not an .exe.

If you want to generate an executable you must use:

TEMPLATE = app

Plus:

To make it easier to include the library in your project, I have created this project whose objective is to provide a .pri that is easy to link to any project with .pro. To do this you must follow the following steps:

Download the project
Add include(/path/of/SMTPEmail.pri) to your .pro
Includes using #include <SmtpMime>
