Question

我编译了OpenCV 2.4.10以使用Qt 5.4 mingw 64位。当我编译加载图片的最基本示例时，它会出现以下错误：

退出，代码为-1073741515

有谁知道这意味着什么以及如何解决它？

QT      += core
QT      += gui
TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

TEMPLATE = app

SOURCES += main.cpp

INCLUDEPATH += C://opencv2_build//install//include
LIBS += C://opencv2_build//bin//*.dll

Answer 1

错误代码表示＆＃34;依赖缺失＆＃34;。 QT中OpenCV的工作配置应如下所示：

LIBS += -LC:\\Programs\\opencv24\\opencv_bin2\\bin \
    libopencv_core240d \
    libopencv_highgui240d \
    libopencv_imgproc240d \
    libopencv_features2d240d \
    libopencv_calib3d240d \

如果您未正确链接OpenCV，则会出现错误。这是一个如何正确链接应用程序（将其放在.pro文件中）的示例：

win32 {
    OPENCV_LIB_DIR = $$PWD/libs/opencv/Windows
    INCLUDEPATH += $$PWD/include/opencv/Windows
}

linux {
    OPENCV_LIB_DIR = $$PWD/libs/opencv/Linux
    INCLUDEPATH += $$PWD/include/opencv/Linux
    LIBS += -L$$OPENCV_LIB_DIR
}

message(OpenCV Library directory: $$OPENCV_LIB_DIR)
LIBS += -L$$OPENCV_LIB_DIR

win32 {
    LIBS += -lopencv_core248
    LIBS += -lopencv_calib3d248
    LIBS += -lopencv_contrib248
    LIBS += -lopencv_features2d248
    LIBS += -lopencv_flann248
    LIBS += -lopencv_gpu248
    LIBS += -lopencv_highgui248
    LIBS += -lopencv_imgproc248
    LIBS += -lopencv_legacy248
    LIBS += -lopencv_ml248
    LIBS += -lopencv_nonfree248
    LIBS += -lopencv_objdetect248
    LIBS += -lopencv_ocl248
    LIBS += -lopencv_photo248
    LIBS += -lopencv_stitching248
    LIBS += -lopencv_superres248
    LIBS += -lopencv_video248
    LIBS += -lopencv_videostab248
}


linux {
    LIBS += -lopencv_core
    LIBS += -lopencv_calib3d
    LIBS += -lopencv_contrib
    LIBS += -lopencv_cuda
    LIBS += -lopencv_cudaarithm
    LIBS += -lopencv_cudabgsegm
    LIBS += -lopencv_cudacodec
    LIBS += -lopencv_cudafeatures2d
    LIBS += -lopencv_cudafilters
    LIBS += -lopencv_cudaimgproc
    LIBS += -lopencv_cudaoptflow
    LIBS += -lopencv_cudastereo
    LIBS += -lopencv_cudawarping
    LIBS += -lopencv_features2d
    LIBS += -lopencv_flann
    LIBS += -lopencv_highgui
    LIBS += -lopencv_imgproc
    LIBS += -lopencv_legacy
    LIBS += -lopencv_ml
    LIBS += -lopencv_nonfree
    LIBS += -lopencv_objdetect
    LIBS += -lopencv_optim
    LIBS += -lopencv_photo
    LIBS += -lopencv_shape
    LIBS += -lopencv_softcascade
    LIBS += -lopencv_stitching
    LIBS += -lopencv_superres
    LIBS += -lopencv_ts
    LIBS += -lopencv_video
    LIBS += -lopencv_videostab
}

请注意，我使用-L标志来说明库文件夹是什么，然后针对每个DLL（Windows）或.so（Linux）使用-l标志。关于如何实际链接库，您有几个不同的选项，但这种方法适合我。希望这有帮助！
