我想在opensuse 13.1下用gdb调试Opencv:
我可以进入某些功能,例如imshow
,,waitKey
但我不能进入其他功能,例如imread
,,namedWindow
它显示:
29 image = cv::imread(name);
(gdb) s
std::allocator<char>::allocator (this=0x7fffffffdc7f)
at /usr/src/debug/gcc-4.8.1-20130909/obj-x86_64-suse-linux/x86_64-suse-linux/libstdc++-v3/include/bits/allocator.h:113
113 allocator() throw() { }
这是我的步骤:
测试4.cpp:
#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv )
{
Mat image;
image = imread( "LinuxLogo.jpg", 1 );
if ( !image.data )
{
printf("No image data \n");
return -1;
}
namedWindow("Display Image", CV_WINDOW_AUTOSIZE );
imshow("Display Image", image);
waitKey(0);
return 0;
}
我的生成文件:
OpencvDebugLibDir=/home/ry/lib
CFLAGS=-g -I$(OpencvDebugLibDir)/include/opencv -I$(OpencvDebugLibDir)
LIBS=$(OpencvDebugLibDir)/lib
test4:test4.cpp
g++ $(CFLAGS) -o $@ $< -L$(LIBS) -lopencv_highgui -lopencv_core -Wl,-rpath=/home/ry/lib/lib
运行 gdb:
gdb test4 -d /home/ry/learn/opencv/install/OpenCV/opencv-2.4.9/modules/core/src -d /home/ry/learn/opencv/install/OpenCV/opencv-2.4.9/modules/highgui/src
