missing opencv.pc

After I build opencv the files are all there, but there is no opencv.pc file so I can't use pkg-config to find the libraries. I tried building it using the buildOpenCV.sh and installing the package created in buildAndPackageOpenCV.sh, but in both there is no opencv.pc file. I've look everywhere on my jetson, but the file isn't there.

Did you install OpenCV using the .deb file that buildAndPackageOpenCV.sh created?

jath03 commented

First I installed it using buildOpenCV.sh, then I rebuilt it with buildAndPackageOpenCV.sh and installed all the .deb files

jetsonhacks commented

Did you install the -dev deb file?

jath03 commented

yes

jath03 commented

Everything looked like it installed correctly, but the opencv.pc file isn't there

jath03 commented

nvm I found it. Not sure how I didn't see it earlier

jetsonhacks commented

good to hear

jath03 commented

sorry, I just ran apt-file search opencv.pc which found the file that was supposed to be there, but it's not actually there

jath03 commented

sudo find / -iname "opencv.pc" doesn't find anything

BTW I did change a few lines of the cmake command in the build files and the opencv version.

cmake -j 4 -D CMAKE_BUILD_TYPE=RELEASE \
     -D CMAKE_INSTALL_PREFIX=${CMAKE_INSTALL_PREFIX}  \
     -D WITH_CUDA=ON \
     -D CUDA_ARCH_BIN=${ARCH_BIN} \
     -D CUDA_ARCH_PTX="" \
     -D ENABLE_FAST_MATH=ON \
     -D CUDA_FAST_MATH=ON \
     -D WITH_CUBLAS=ON \
     -D WITH_LIBV4L=ON \
     -D WITH_GSTREAMER=ON \
     -D WITH_GSTREAMER_0_10=OFF \
     -D WITH_QT=ON \
     -D WITH_OPENGL=ON \
     -D CPACK_BINARY_DEB=ON \
     -D OPENCV_EXTRA_MODULES_PATH=/home/nvidia/Downloads/opencv_contrib-4.0.1/modules       
     ../

I changed the opencv version to 4.01

You are missing -D OPENCV_GENERATE_PKGCONFIG=ON
