Thanks, worked fine for me.

Suggestion:
add checkinstall to the installed packages list, and then make line 23: sudo make install && sudo checkinstall

Also, I've seen another install guide that includes libtbb2 and libpng-dev in the installed packages list. Do you think it's worthwhile including these?

If someone looking to install it in Ubuntu 17 use another version of the compiler
For example:
https://gist.github.com/ibogun/ec0a4005c25df57a1b9d#file-gistfile1-txt
and change complier
-DCMAKE_CXX_COMPILER=/usr/bin/g++-4.9 CMAKE_C_COMPILER=/usr/bin/gcc-4.9

Hello everybody. I'm sorry for taking so long to answer you all. I didn't receive any notification of your comments here, so I had no idea this script wasn't working.

I've updated the script and now it works flawlessly on Ubuntu 17.04 (probably works on 16.04, 16.10 and 17.10 too, but I can't confirm). There were 2 problems:
1st - OpenCV2.4.13 makefile isn't compatible with GCC 6.x. OpenCV2.4.13.4 corrects it;
2nd - Python needs python-opencv package, and now I've included it in this script.


Now answering your questions:

@vasu1765 - Sorry, I don't know the origin of your problem nor how to correct it. You probably already solved it (at least that's what I hope for), but I suggest you and everybody with a similar problem to uninstall opencv with make uninstall and rebuild it paying attention to warnings and error messages.

@manish988 @soumyadeep1997 @wfs @MrNocTV @suresh88 - If your OpenCV2 build was successfull, sudo apt-get install python-opencv should fix it as @drsagitn pointed out (but avoid running this script and installing the opencv-python pip package).

@tkotha @TeixeiraRafael @bharathkotari - Unfortunately I use OpenCV only to build other people's code and thus my OpenCV knowledge is scarse, so I have no idea :c

@jyothi2958 - The -fPIC build parameter is already in OpenCV2.4.13.4 makefile. I suggest that you remove your already built libs running make uninstall on your installation folder and rebuild opencv with the updated script.

@eran-misi and @omar-JHA - " # 2 cores" is a comment and thus anything after the hash is ignored by bash. Anyway, thanks for trying to help @jyothi2958 out :)

@Napoleon-BlownApart - checkinstall is included in the long dependency list. Maybe it's a good idea to use checkinstall but I don't know how to properly work with it. I've tried to do it in my last clean build (yesterday) of opencv and I believe I've made a f***-up running it. For an automated script, it's ideal that checkinstall command receives the needed parameters to create a .deb so the user isn't prompted to make decisions (it's error prune). When I learn how to properly work with it, I'll try to remember to come here and update the script.
As for libpng_dev, as far as I remember there was some incompatibility with OpenCV2.4.13 thus this script uses libpng12_dev. Maybe I'm mistaken, I really can't remember. And I have no idea about the impact of using or not libbb2. It probably won't hurt to include it.

@root-sudip - I'm not sure if it's possible to use OpenCV 2.4 wity python3. Every python3 build I've seen uses OpenCV3.

@DiwakarVartharajan - The pip package is not necessary. sudo apt-get install python-opencv only installs bindings for the OpenCV lib this script builds while pip install opencv-python has bindings AND binaries (opencv core dynamic libs). If you run this script and install the pip package, it's possible that your build will have conflicting libs.

@pab12play - OpenCV2.4.13.4 fixes it, so you don't need to downgrade your GCC anymore :)

@SportsMUST - Don't run it with sudo. It's possible (but not probable) that you'll need to chmod the script file to be able to run it. As for fatal error: opencl_kernels.hpp: No such file or directory error, I suggest you to use the updated script and make a clean build.

@Piusha - The problem is that your machine has QT, but it's a version prior to 4.x and OpenCV2.4 requires QT 4.x. I believe running apt-get install libqt4-core libqt4-dev libqt4-gui qt4-dev-tools before running the updated script will solve your problem.

@SutanuNandigrami - I believe your solution isn't necessary anymore as OpenCV2.4.13.4 corrects build bugs :)


If anyone else wants to reach me to discuss this script, please use @mentions. I believe that way I'll be notified of your messages :)

for anybody else getting CUDA-related errors when running the cmake command, you can add another flag to skip the CUDA stuff (and then install it later on, which is what I did):

-D WITH_CUDA=OFF

Not sure how, but does anyone know how to add more recent GPU architectures for it to build so the annoying nvcc warning stops appearing? I know you can even specify like "Kepler" or "Fermi" (not sure about Maxwell). Either that or add -D WITH_CUDA=OFF like @wkentdag said.

Notes for Ubuntu 17.10.

  • libgstreamer is upgraded to v1.0 so it's not possible to install v0.10 via apt.
    Unable to locate package libgstreamer0.10-dev
  • And also every command related to libgstreamer is broken since the version is changed.
  • libjasper-dev is removed from the repository. I couldn't find the replacement at the moment.
    Unable to locate package libjasper-dev
  • libpng is upgraded to v16. So you should use "libpng-dev" instead. This should install all development headers and the current version from the repository.

Notes for Ubuntu 17.10.

  • libgstreamer is upgraded to v1.0 so it's not possible to install v0.10 via apt.
    Unable to locate package libgstreamer0.10-dev
  • And also every command related to libgstreamer is broken since the version is changed.
  • libjasper-dev is removed from the repository. I couldn't find the replacement at the moment.

Hello,

I get a strange error during the cmake process itself (running on Ubuntu16.04). It says -

/home/aashishsharma/Desktop/opencv-2.4.13.5/release/CMakeFiles/CMakeTmp/CheckSymbolExists.cxx:8:19: error: ‘Q_WS_WIN’ was not declared in this scope
return ((int*)(&Q_WS_WIN))[argc];

Can anybody please help me out? I can share the entire log if needed. Thanks!

Thanks!!!
Instructions works well on ubuntu 18 as well just by using the newest set of packages available for the distro
