以下を使用して opencv 静的ライブラリをビルドします。
BUILD_SHARED_LIBS = OFF
build_opencv_core = ON
build_opencv_imgproc = ON
build_opencv_highgui = ON
WITH_FFMPEG = ON
WITH_PNG = ON
WITH_JASPER = ON
WITH_TIFF = ON
WITH_OPENEXR = ON
その他OFF
ライブラリのビルドは良い
そして今、新しいQtプロジェクトを作成します
INCLUDEPATH += -I/usr/local/include
LIBS += -L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui
main.cpp で
#include <QCoreApplication>
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
int main(int argc,char** argv)
{
QCoreApplication a(argc,argv);
CvCapture* capture = cvCaptureFromCam(0);
return a.exec();
}
しかし、プロジェクトをビルドすると、次のエラーが発生します。
