我有一个目标为 lib 的项目,另一个目标是应用程序

第一个项目成功构建为静态动态(共享)库。

第二个项目成功链接了一个动态库,但是无法链接一个静态库。
出现许多错误消息,例如LNK2001: unresolved external symbol

app.pro:

TEMPLATE = app
CONFIG += static link_prl ordered
DEFINES += QT_NODLL
QT += core gui network xml

...

# --- LINK QUAZIP LIB SHARED ---

据我了解, qmake 希望一个dll链接到它。
我怎样才能告诉我我要构建一个静态应用程序,并让它在静态生成的库中查找外部对象?

最佳答案

静态链接QuaZipCONFIG += staticlib在您的qmake文件中。

或确保在实际包含应用程序中的任何QuaZip header 之前已定义QUAZIP_STATIC

关于windows - Qt链接静态建库,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/15807605/
