qt - 将 OpenCV 库链接到 Qt

Question

我正在尝试创建一个界面应用程序，我需要在其中使用 OpenCV 在一个窗口中显示两个视频。我试过 Qt 但我有一些错误，如“未解析的外部符号”。我想我没有很好地将 Qt 链接到 OpenCV 库。这是我的“.pro”文件:

#-------------------------------------------------

QT += core gui

greaterThan(QT_MAJOR_VERSION, 4) : QT += widgets

TARGET = test_Qt
TEMPLATE = app


SOURCES += main.cpp\
dialog.cpp

HEADERS += dialog.h

FORMS += dialog.ui

INCLUDEPATH += D:\\OpenCV231\\opencv\\build\\include

LIBS += -LD:\\OpenCV231\\mybuild\\lib\\Debug \
    -lopencv_calib3d231d.lib \
    -lopencv_contrib231d.lib \
    -lopencv_core231d.lib \
    -lopencv_features2d231d.lib \
    -lopencv_flann231d.lib \
    -lopencv_gpu231d.lib \
    -lopencv_haartraining_engined.lib \
    -lopencv_highgui231d.lib \
    -lopencv_imgproc231d.lib \
    -lopencv_legacy231d.lib \
    -lopencv_ml231d.lib \
    -lopencv_objdetect231d.lib \
    -lopencv_ts231d.lib \
    -lopencv_video231d.lib

谁能帮帮我？谢谢

Answer 1

将 .lib 放在这些地方就足够了:

-lopencv_calib3d231d.lib \
                    ^^^^

应该会自动找到静态库，因此只需使用此架构即可:

-lopencv_calib3d231d \

如果您尝试明确指定扩展名，它将查找 (lib)opencv_food.lib.{lib/dll}。

如果您希望获取静态库路径而不是动态库，您还可以指定整个静态库路径。
