Qt链接静态构建的lib

时间:2013-04-04 09:37:04

标签: windows qt static-libraries qmake

我的项目定位为 lib ,另一个项目定位为应用

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动态库,但无法链接静态。 会出现许多错误消息,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 ---

#LIBS += -L$$quote(C:/Qt/quazip/build-quazip-0.5.1-Qt_4_8_3_shared-Debug/quazip/debug) -lquazip
#PRE_TARGETDEPS += $$quote(C:/Qt/quazip/build-quazip-0.5.1-Qt_4_8_3_shared-Debug/quazip/debug/quazip.lib)

# --- LINK QUAZIP LIB STATIC ---

LIBS += -L$$quote(C:/Qt/quazip/build-quazip-0.5.1-Qt_4_8_3_static-Release/quazip/release) -lquazip
PRE_TARGETDEPS += $$quote(C:/Qt/quazip/build-quazip-0.5.1-Qt_4_8_3_static-Release/quazip/release/quazip.lib)

据我了解, qmake 想要一个dll链接到它。 我怎么能告诉它我想构建一个静态应用程序并让它在静态构建的lib中寻找外部?

答案 0 :(得分:2)

静态链接QuaZip需要 CONFIG += staticlib 在你的qmake文件中。

或者确保在您从应用程序中实际包含任何QuaZip标头之前定义了QUAZIP_STATIC
