OpenCV 2.4.10 + Qt Creator 3.2.0和Qt5.4.0 MingW 64bits Windows 7 - “退出代碼-1073741515”

Question

我已經編譯了OpenCV 2.4.10以使用Qt 5.4 mingw 64位。 當我編譯加載圖片的最基本的例子時，它給出以下錯誤：

退出，代碼為-1073741515

有誰知道這意味着什么以及如何解決它？

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

錯誤代碼表示“依賴性缺失”。 QT中OpenCV的工作配置應如下所示：

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

看起來像是一個錯誤，你沒有正確鏈接OpenCV。 這是一個如何正確鏈接應用程序（將其放在.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
}

請注意，我使用-L標志來說明庫文件夾是什么，然后使用-l標志針對每個DLL（Windows）或.so（Linux）。 關於如何實際鏈接庫，您有幾個不同的選項，但這種方法適合我。 希望這可以幫助！
