I am trying to compile & run the ukf test in the following directory:

~/opencv_contrib/modules/tracking/test/test_ukf.cpp

when I try to compile it using ( g++ test_ukf.cpp ) command I get:

In file included from test_ukf.cpp:42:0: test_precomp.hpp:13:26: fatal error: opencv2/ts.hpp: No such file or directory compilation terminated.

Then I specify the include directory where ts.hpp exists using : g++ -o app -I/home/akde/opencv/modules/ts/include/ test_ukf.cpp But this time I get

In file included from test_precomp.hpp:13:0, from test_ukf.cpp:42: /home/akde/opencv/modules/ts/include/opencv2/ts.hpp:22:22:> fatal error: cvconfig.h: No such file> or directory compilation terminated.

Finally I searched for the cvconfig.h and found it in 2 places:

1-/home/akde/opencv/build/opencv2/cvconfig.h

2-/home/akde/opencv/build/cvconfig.h

I specified the locations and compiled using:

g++ -o app -I/home/akde/opencv/modules/ts/include/ -I/home/akde/opencv/build/opencv2 test_ukf.cpp

and

g++ -o app -I/home/akde/opencv/modules/ts/include/ -I/home/akde/opencv/build test_ukf.cpp

and

g++ test_ukf.cpp -o app "pkg-config --cflags --libs opencv" -I/home/akde/opencv/modules/ts/include/ -I/home/akde/opencv/build

This time I get a gigantic error:

  • the tests are usually built along with the opencv libs, with BUILD_TESTS=ON. (it's not really expected, that you do that later, manually)
  • it should be (backticks) around the pkg-config part, not " `
  • you also need to compile test_main.cpp from there
  • you also need to link to -lopencv_ts and set up the correct -L flag for this (it is not installed to your usr/loca/lib folder

thx for swift reply. - it should be (backticks) around the pkg-config part, not " **: they were. I changed ` into " just to make them more visible in the question. - **the tests are usually built along with the opencv libs, with BUILD_TESTS=ON. (it's not really expected, that you do that later, manually) : to be honest I did not understand what should I do about this bullet. Should I rebuild the opencv with cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_TESTS=ON ..? - you also need to link to -lopencv_ts and set up the correct -L flag for this (it is not installed to your usr/loca/lib folder : How can I do that? I searched for opencv_ts and find only 3 files namely opencv_ts_RELEASE.gch, opencv_ts_pch_dephelp.cxx.o and opencv_ts_pch_dephelp.cxx - compiling main results in error

Should I rebuild the opencv with cmake -D CMAKE_BUILD_TYPE=RELEASE -D_TESTS=ON ..?

that would be the most easy way.

did you have at least BUILD_opencv_ts=ON before ? else it won't build the opencv_ts lib. there should be a libopencv_ts.a in opencv/build/lib and you need to link against that

just as u said the "libopencv_ts.a" exists in ~/opencv/build/lib so I build using the following

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=/home/akde/opencv_contrib/modules -D BUILD_EXAMPLES=ON -D BUILD_opencv_python2=OFF -D WITH_FFMPEG=1 -D WITH_CUDA=ON -D CUDA_GENERATION=Kepler -D_TESTS=ON ..

then sudo make -j8 sudo make install

Then tried to compile with g++ test_main.cpp -o app pkg-config --cflags --libs opencv -I/home/akde/opencv/modules/ts/include/ -I/home/akde/opencv/build I got the same errors.

Then I try to link /home/akde/opencv/build/lib/ where the opencv_ts exists with the following

sudo ln -s /home/akde/opencv/build/lib/opencv_ts /usr/local/bin

sudo ln -s /home/akde/opencv/build/lib/ /usr/local/bin

and tried to compile with *g++ test_main.cpp -o app pkg-config --cflags --libs opencv -I/home/akde/opencv/modules/ts/include/ -I/home/akde/opencv/build -L/home/akde/opencv/build/lib/opencv_ts * but again the same error

burakakde gravatar imageburakakde ( 2018-08-09 07:06:25 -0500 )edit

it should be:

-L/home/akde/opencv/build/lib -lopencv_ts

(and again, this lib is neither in the pkg list, nor does it get installed to /usr/local/lib)

ts.cpp is in /home/akde/opencv/modules/ts/src/

in test_precomp.hpp, when change the #include "opencv2/ts.hpp" line to #include "/home/akde/opencv/modules/ts/src/ts.hpp" I still get the test_precomp.hpp:14:51: fatal error: /home/akde/opencv/modules/ts/src/ts.hpp: No such file or directory compilation terminated. error. File that is looked for is exactly in the mentioned path, but still the compiler cannot see that. Why is it?
