unable to complete 'make -j7' with opencv_contrib modules
Cmake can not compile extra modules from opencv_contrib. I am following theese instructions . Sorry for my length of my Ask, but giving more info about my Issues. This is example of my CMake options:
cmake -DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DINSTALL_C_EXAMPLES=OFF \
-DINSTALL_PYTHON_EXAMPLES=OFF \
-DBUILD_EXAMPLES=OFF
-DOPENCV_EXTRA_MODULES_PATH=/home/luke/cv/opencv_contrib/modules ..
Till here it is fine. Configured. Generated (maybe with basicly some warnings etc.) :
-- Configuring done
-- Generating done
-- Build files have been written to: /home/luke/cv/opencv-3.4.0/build
But when I enter in build directory "make -j7"
Scanning dependencies of target opencv_core_pch_dephelp
[ 0%] Built target gen-pkgconfig
[ 0%] Building CXX object 3rdparty/openexr/CMakeFiles/IlmImf.dir/Half/half.cpp.o
...(HERE will comes my ISSUES)
then during a procedure, on the first module from opencv_contrib I will EVERYTIME get many of theese same couples of errors:
Scanning dependencies of target opencv_test_reg_pch_dephelp

This happens I think with each module from opencv_contrib. Ok but this type of syntax errors cannot be in each module..
I have Ubuntu version 14.04LTS and I am using the last released CMake version 3.12.0. Tried older and tried also cmake-gui which version is about 2.8. Does anybody know, what problem it could be ? :( I have tried this several times and don´t know how to solve it.
Just in my opinion: it looks like there could be a problem with a compiler. I don't know maybe it doesn't have some key parameters like c++11 ? But this should CMake make it with their 10 thousands of lines Makefile.. and with their gear. Or Maybe wrong(not good ...
your opencv & contrib versions do not match !
make sure to use the exact same version for opencv and opencv_contrib. if your main is 3.4.0, then you need to check out the very same contrib release. better: update both repos to current 3.4 branch (NOT the same as 3.4.0)
and no fear, this a known and easy solvable problem !
Well, If there are more opencv_contrib versions, where I could find it and clone or donwload? I can see only one URL here , there is only 1 repository with opencv_contrib. And Even I am not sure what version it is. only on label near modules folder there is " Merge remote-tracking branch 'upstream/3.4' into merge-3.4 " so I guessed it is 3.4.0 version. I tried again git clone from main instructions both opencv and opencv_contrib and problems are again with "make -j7". You really think that is easy solvable problem? I thought so but i really dont know.. Where do you now think problems could be? :|
Maybe there are some problems in configuration and generation what cause theese problems?
there are branches and releases to choose from. if you don't specify anything, you'll get the master(4.0) branch
use git:
apart from that, your cmake seems to have a download problem. please inspect
/home/luke/cv/last/oc/opencv/build/CMakeDownloadLog.txtAah I see now.. Have allready forgotted about "-b" branches. Well I try prepare again theese 2 versions from this branch. You are right, this is that Log list. It is Available - Basicly from browser I can download that raw.githubusercontent URLs, Cmake doesn't. Unsuported protocol etc or disabled in libcurl. So this really could cause issues in 'make' command.
yea, you can download those things manually, but it's painful. maybe you can update your libbcurl instead ?
yea. I was doing that. installed the last version of libcurl, also OpenSSL, which is probably connected. I have done
./configure --with-ssl. When I see configured log of libcurl there I see HTTPS on enum of protocols. Soo that should be supported. But Cmake while configuration and generating makes still the same fails with downloads written in warnings ( shown above in my links ). This is being harder then I thought. CMake tells: not supported or disabled in libcurl but libcurl says (it seems like..) suported. Ah. I am thinking about it but dont know what else is wrong.It seems like maybe CMake is not using libcurl but is set to use some own lib? I was searching about it but dont know how to set it. Or How make sure that cmake is really set to use libcurl which I have updated in my UNIX system.
