Hi, I'm new to linux, and need a bit of help. I need to use openCV
with cvBlob on linux, so installed openCV with these commands:
$ sudo add-apt-repository ppa:gijzelaar/opencv2
$ sudo apt-get install libcv2.1 libcv-dev libcvaux2.1 libcvaux-dev
libhighgui2.1 libhighgui-dev opencv-doc python-opencv
$ export LD_LIBRARY_PATH=/home/opencv/lib
$ export PKG_CONFIG_PATH=/home/opencv/lib/pkgconfig
$ pkg-config --cflags opencv
-I/usr/include/opencv
$ pkg-config --libs opencv
-lcxcore -lcv -lhighgui -lcvaux -lml
and followed by installing cvBlob to /home/steffen/SDK/cvBlob. I
compiled it with:
$ cmake-gui
set source til /home/steffen/SDK/cvBlob
set build til /home/steffen/SDK/cvBlob/bin
set openCV_DIR til /usr/include/opencv
configured and generated.
$ cd /bin
$ sudo make install
all seemed to install correctly.
I then tried compiling the sample project (/cvBlob/sample) with:
$ make
which gave a LOT of errors, and then with:
$ g++ red_object_tracking.cpp -o sample pkg-config --cflags --libs
opencv
which returned the following:
/tmp/ccRtslPR.o:
In function `main':
red_object_tracking.cpp:(.text+0x37c): undefined reference to
`cvLabel'
red_object_tracking.cpp:(.text+0x39d): undefined reference to

`cvRenderTracks'
red_object_tracking.cpp:(.text+0x5e1): undefined reference to
`cvSaveImageBlob'
collect2: ld returned 1 exit status
can anyone tell me what I did wrong, and how to fix this?
Hope you can help!
