我刚接触Qt,但有一个错误无法解决。
我有一堆Windows(VS2005)的静态库文件(.lib
),现在想测试它们是否能与Qt很好地配合使用。因此,我选择了我拥有的最简单的库(称为MessageBuffer
)。
于是我把MessageBuffer.h
添加到main.cpp
中,并将这些文件的位置添加到.pro
的INCLUDEPATH
中。
直到那时,一切似乎都很好,我可以使用类和Qt IDE显示所有方法等。所以对我来说,它看起来已经找到了.h文件。
现在我像这样在.pro
中添加了MessageBuffer.lib
(VS2005/Debug版本):
LIBS += E:/SharedLibrary/lib/MessageBufferd.lib
我也尝试了以下方法:
win32:LIBS += E:/SharedLibrary/lib/MessageBufferd.lib
LIBS += -LE:/SharedLibrary/lib -lMessageBufferd
win32:LIBS += -LE:/SharedLibrary/lib -lMessageBufferd
这是我的.pro
文件的内容:
QT += opengl
TARGET = SilverEye
TEMPLATE = app
INCLUDEPATH += E:/SharedLibrary/MessageBuffer
SOURCES += main.cpp \
silvereye.cpp
HEADERS += silvereye.h
FORMS += silvereye.ui
OTHER_FILES +=
win32:LIBS += E:/SharedLibrary/lib/MessageBufferd.lib
它们都给我同样的错误:(即使我不包括 .lib
也是如此)

有人可以帮忙吗?
