Question

我在向Qt Creator中添加OpenCV库时遇到问题。

这是我的代码：

INCLUDEPATH += "C:/OpenCV/opencv/build/include" \

CONFIG(debug,debug|release) {



LIBS += -L"C:/OpenCV/opencv/build/x86/vc12/lib" \
    -lopencv_core2413d \
    -lopencv_calib3d2413d \
    -lopencv_contrib2413d \
    -lopencv_features2d2413d \
    -lopencv_flann2413d \
    -lopencv_gpu2413d \
    -lopencv_highgui2413d \
    -lopencv_imgproc2413d \
    -lopencv_videostab2413d
}

CONFIG(debug,debug|release) {
    DEFINES += QT_NO_WARNING_OUTPUT QT_NO_DEBUG_OUTPUT
    LIBS +=  -L"C:/OptiNavCV/opencv/build/x86/vc12/lib" \
    -lopencv_core2413 \
    -lopencv_calib3d2413 \
    -lopencv_contrib2413 \
    -lopencv_features2d2413 \
    -lopencv_flann2413 \
    -lopencv_gpu2413 \
    -lopencv_highgui2413 \
    -lopencv_imgproc2413 \
    -lopencv_videostab2413
    }
}

错误： C：\ Qt \ Qt5.5.1 \ Tools \ QtCreator \ bin \ jom.exe -f Makefile.Release cl -c -nologo -Zc：wchar_t -FS -O2 -MD -Zc：strictStrings -GR -W3 -w34100 -w34189 -w44996 -EHsc -DUNICODE -DWIN32 -DWIN64 -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DNDEBUG -I。。\ TestAppQt -I。 -I ........ \ OptiNavCV \ opencv \ build \ include -I ........ \ Qt \ Qt5.5.1 \ 5.5 \ msvc2013_64 \ include -I ........ \ Qt \ Qt5.5.1 \ 5.5 \ msvc2013_64 \ include \ QtWidgets -I ........ \ Qt \ Qt5.5.1 \ 5.5 \ msvc2013_64 \ include \ QtGui -I ........ \ Qt \ Qt5.5.1 \ 5.5 \ msvc2013_64 \ include \ QtANGLE -I ........ \ Qt \ Qt5.5.1 \ 5.5 \ msvc2013_64 \ include \ QtCore -Irelease -I。 -I ........ \ Qt \ Qt5.5.1 \ 5.5 \ msvc2013_64 \ mkspecs \ win32-msvc2013 -Forelease \ @C：\ Users \ szymo \ AppData \ Local \ Temp \ mainwindow.obj.11752.15.jom mainwindow.cpp link / NOLOGO / DYNAMICBASE / NXCOMPAT / INCREMENTAL：NO / SUBSYSTEM：WINDOWS＆＃34; / MANIFESTDEPENDENCY：type =＆＃39; win32＆＃39;命名=＆＃39; Microsoft.Windows.Common - 控制＆＃39;版本=＆＃39; 6.0.0.0＆＃39;公钥=＆＃39; 6595b64144ccf1df＆＃39;语言=＆＃39; ＆＃39; ProcessorArchitecture用于=＆＃39; ＆＃39;＆＃34; / MANIFEST：embed /OUT:release\TestAppQt.exe @C：\ Users \ szymo \ AppData \ Local \ Temp \ TestAppQt.exe.11752.1422.jom mainwindow.obj：错误LNK2019：未解析的外部符号＆＃34; void __cdecl cv :: fastFree（void *）＆＃34; （？fastFree @ cv @@ YAXPEAX @ Z）在函数＆＃34; public中引用：__ cdecl MainWindow :: MainWindow（类QWidget *）＆＃34; （?? 0MainWindow @@ @ QEAA @@@ PEAVQWidget Z） mainwindow.obj：错误LNK2019：未解析的外部符号＆＃34; public：__ cdecl cv :: _ InputArray :: _ InputArray（class cv :: Mat const＆amp;）＆＃34;函数＆＃34; public：__ cdecl MainWindow :: MainWindow（class QWidget *）＆＃34; （?? 0MainWindow @@ @ QEAA @@@ PEAVQWidget Z） mainwindow.obj：错误LNK2019：未解析的外部符号＆＃34; public：void __cdecl cv :: Mat :: deallocate（void）＆＃34; （？deallocate @ Mat @ cv @@ QEAAXXZ）在函数＆＃34; public中引用：__ cdecl MainWindow :: MainWindow（类QWidget *）＆＃34; （?? 0MainWindow @@ @ QEAA @@@ PEAVQWidget Z） mainwindow.obj：错误LNK2019：未解析的外部符号＆＃34; int __cdecl cv :: _ interlockedExchangeAdd（int *，int）＆＃34;函数＆＃34; public：__ cdecl MainWindow :: MainWindow（class QWidget *）＆＃34; （?? 0MainWindow @@ @ QEAA @@@ PEAVQWidget Z） mainwindow.obj：错误LNK2019：未解析的外部符号＆＃34; void __cdecl cv :: imshow（class std :: basic_string，class std :: allocator＆gt; const＆amp;，class cv :: _ InputArray const＆amp;）＆＃34 ; （？imshow @ cv @@ YAXAEBV？$ basic_string @ DU？$ char_traits @ D @ std @@ V？$ allocator @ D @ 2 @@ std @@ AEBV_InputArray @ 1 @@ Z）在函数＆＃34; public中引用：__ cdecl MainWindow :: MainWindow（类QWidget *）＆＃34; （?? 0MainWindow @@ @ QEAA @@@ PEAVQWidget Z） mainwindow.obj：错误LNK2019：未解析的外部符号＆＃34; class cv :: Mat __cdecl cv :: imread（class std :: basic_string，class std :: allocator＆gt; const＆amp;，int）＆＃34; （？imread @ cv @@ YA？AVMat @ 1 @ AEBV？$ basic_string @ DU？$ char_traits @ D @ std @@ V？$ allocator @ D @ 2 @@ std @@ H @ Z）在函数＆＃中引用34; public：__ cdecl MainWindow :: MainWindow（class QWidget *）＆＃34; （?? 0MainWindow @@ @ QEAA @@@ PEAVQWidget Z） release \ TestAppQt.exe：致命错误LNK1120：6个未解析的外部 jom：C：\ Users \ szymo \ Documents \ build-TestAppQt-Desktop_Qt_5_5_1_MSVC2013_64bit-Release \ Makefile.Release [release \ TestAppQt.exe]错误1120 jom：C：\ Users \ szymo \ Documents \ build-TestAppQt-Desktop_Qt_5_5_1_MSVC2013_64bit-Release \ Makefile [release]错误2 09:52:59：进程＆＃34; C：\ Qt \ Qt5.5.1 \ Tools \ QtCreator \ bin \ jom.exe＆＃34;退出代码2。构建/部署项目TestAppQt时出错（工具包：Desktop Qt 5.5.1 MSVC2013 64bit）执行步骤＆＃34;制作＆＃34;

您正在尝试链接32位库（opencv_core）

-L"C:/OptiNavCV/opencv/build/x86/vc12/lib" \

...

LNK2019: unresolved external symbol "void __cdecl cv::fastFree(void *)"

到x64项目

TestAppQt (kit: Desktop Qt 5.5.1 MSVC2013 64bit)
