我正在尝试使用Windows 10
和Qt5.12
建立一个项目。小程序正在使用可用的smtp
协议here。我可以确认Windows
上有OpenSSL 1.1.1c 28 May 2019
。在我的Ubuntu 19.04
上,相同的程序会正常编译并运行,但没有在Windows
上运行。
我将在错误的打印屏幕下方附加;但是这些主要有两种类型:
1) inconsistent dll linkage
2) definition of dllimport static data member not allowed
<< img src =“ https://image.soinside.com/eyJ1cmwiOiAiaHR0cHM6Ly9pLmltZ3VyLmNvbS9tZkJHdWFsLnBuZyJ9” alt =“错误”>
跟随this link,似乎Windows
需要其“自己的”包含(即#include <windows....
),但是在我的情况下,上述链接中的smtp
库没有任何#include <windows>
,并且不知道是否它们必须生成。看来他们不是我发现的帖子
此外,我正在阅读this post too,因为我认为我可能有用,但没有任何信息可以帮助我解决问题
我挖了更多的东西,实际上去了windows includes
的位置,以下是我能够找到的路径,但是不知道这是否有用:
<< img src =“ https://image.soinside.com/eyJ1cmwiOiAiaHR0cHM6Ly9pLmltZ3VyLmNvbS9mY1BNVjhZLnBuZyJ9” alt =“包括”>
在我发的所有帖子中,问题似乎都存在,在这种情况下,Windows
写入.pro
文件。在我的.pro
文件下面。请注意,我已将此存储库克隆到我的windows 10
中。

编辑
更具体地说,似乎每个有问题的标题都在下面:
class SMTP_EXPORT EmailAddress : public QObject // <-- SMTP_EXPORT
这将导致smtpexports.h,我将其复制到下面:
#ifndef SMTPEXPORTS_H
#define SMTPEXPORTS_H
#ifdef SMTP_BUILD
#define SMTP_EXPORT Q_DECL_EXPORT
#else
#define SMTP_EXPORT Q_DECL_IMPORT
#endif
#endif // SMTPEXPORTS_H
附加编辑
添加DEFINES += SMTP_BUILD
后几乎所有错误都解决了,但是我还剩下两个错误,并且在下面添加了打印屏幕:
<< img src =“ https://image.soinside.com/eyJ1cmwiOiAiaHR0cHM6Ly9pLmltZ3VyLmNvbS9TamVKOW4wLnBuZyJ9” alt =“错误”>
非常感谢您为解决此问题指明了正确的方向。
这些文件被设计为使用定义SMTP_BUILD
设置进行编译,该设置将源添加到库或可执行文件中。您必须添加
DEFINES += SMTP_BUILD
到您的pro
文件。
