Make file error

[chahatahuja24]

Hey, I am having make file error. I am not able to build Linux examples. the error is undefined reference to 'operator new (unsigned long)'. and architecture of optimized files are incompatible with i386 output.

[puku0x]

Oh really ?

You used the default makefile (cvdrone-master\build\linux\makefile), didn't you? "$ sudo apt-get install build-essential" may help you.

In other case (if you wrote your original makefile), the error is showed when you use GCC. Please add "-lstdc++" flag or use g++ compiler.

Unfortunately, I'm not sure CV Drone's compatibility of the i386 system. Please tell me if you solve it.

Thanks, puku0x

Is there any progress ?

hi Sir Thank you for amazing job, however I've some issues when I tried to make file on Ubuntu as Virtual machine in mac g++ ../../src/ardrone/ardrone.o ../../src/ardrone/command.o ../../src/ardrone/config.o ../../src/ardrone/udp.o ../../src/ardrone/tcp.o ../../src/ardrone/navdata.o ../../src/ardrone/version.o ../../src/ardrone/video.o ../../src/main.o -o test.a -O2 -Wall -D__STDC_CONSTANT_MACROS -lm -lpthread -lavutil -lavformat -lavcodec -lswscale -lopencv_calib3d -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_hal -lopencv_highgui -lopencv_imgcodecs -lopencv_imgproc -lopencv_ml -lopencv_objdetect -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_video -lopencv_videoio -lopencv_videostab /usr/bin/ld: cannot find -lopencv_hal /usr/bin/ld: cannot find -lopencv_imgcodecs /usr/bin/ld: cannot find -lopencv_videoio collect2: error: ld returned 1 exit status make: *\ [test.a] Error 1 I know there is something relating to video module however I couldn't solve it till now ... any ideas

[valizada]

which version of opencv u are using? Try to upgrade to 3.0, it should solve this problem

[EngmaherAljehani]

let me check, and coming back again

Thanks !

[EngmaherAljehani]

still having the same issues even after upgrading to 3.0.0

g++ ../../src/ardrone/ardrone.o ../../src/ardrone/command.o ../../src/ardrone/config.o ../../src/ardrone/udp.o ../../src/ardrone/tcp.o ../../src/ardrone/navdata.o ../../src/ardrone/version.o ../../src/ardrone/video.o ../../src/main.o -o test.a -O2 -Wall -D__STDC_CONSTANT_MACROS -lm -lpthread -lavutil -lavformat -lavcodec -lswscale -lopencv_calib3d -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_hal -lopencv_highgui -lopencv_imgcodecs -lopencv_imgproc -lopencv_ml -lopencv_objdetect -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_video -lopencv_videoio -lopencv_videostab /usr/bin/ld: cannot find -lopencv_hal /usr/bin/ld: cannot find -lopencv_imgcodecs /usr/bin/ld: cannot find -lopencv_videoio collect2: error: ld returned 1 exit status make: *\ [test.a] Error 1

[valizada]

Would you please try to run following command to see the list of libraries you have:

pkg-config --libs opencv

And check from the list if -lopencv_hal, -lopencv_imgcodecs and -lopencv_videoio present in there. If not it means that there is a linking problem. You could try to run:

brew link opencv3 —force

And lastly it could be because .o files are not being upgraded after running make. Try to delete all .o files from ../../src/ardrone/ folder and then make

[EngmaherAljehani]

Thanks but that what I have got so far

$ pkg-config --libs opencv /usr/lib/x86_64-linux-gnu/libopencv_calib3d.so /usr/lib/x86_64-linux-gnu/libopencv_contrib.so /usr/lib/x86_64-linux-gnu/libopencv_core.so /usr/lib/x86_64-linux-gnu/libopencv_features2d.so /usr/lib/x86_64-linux-gnu/libopencv_flann.so /usr/lib/x86_64-linux-gnu/libopencv_gpu.so /usr/lib/x86_64-linux-gnu/libopencv_highgui.so /usr/lib/x86_64-linux-gnu/libopencv_imgproc.so /usr/lib/x86_64-linux-gnu/libopencv_legacy.so /usr/lib/x86_64-linux-gnu/libopencv_ml.so /usr/lib/x86_64-linux-gnu/libopencv_objdetect.so /usr/lib/x86_64-linux-gnu/libopencv_ocl.so /usr/lib/x86_64-linux-gnu/libopencv_photo.so /usr/lib/x86_64-linux-gnu/libopencv_stitching.so /usr/lib/x86_64-linux-gnu/libopencv_superres.so /usr/lib/x86_64-linux-gnu/libopencv_ts.so /usr/lib/x86_64-linux-gnu/libopencv_video.so /usr/lib/x86_64-linux-gnu/libopencv_videostab.so -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_objdetect -lopencv_ocl -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videostab

$ brew link opencv3 —force No command 'brew' found, did you mean: Command 'brec' from package 'bplay' (universe) Command 'qbrew' from package 'qbrew' (universe) brew: command not found

I deleted all .o files but still having the same error !

by the way I'm trying to install it on Ubuntu 14.04 LTS ,

[valizada]

I thought you are running it from Mac, brew is a package manager, like apt-get on Ubuntu. So it won't work on Ubuntu. Sorry but in this case I am not sure how to fix it.

[EngmaherAljehani]

Mr.valizada I really appreciate your help and I'm sorry for not explaining that briefly earlier. it runs fine on mac os but I prefer ubuntu since I've done some work on it.

Hi @EngmaherAljehani ,

I have just got it working on Ubuntu 14.04. You need to install OpenCV from source, as the packages don't offer opencv 3. Personally I used the tutorial here [1], while skipping step 8 (about virtualenv).

Please report if you have other issues.

I would recommend removing current opencv before installing the new one.

[EngmaherAljehani]

hi mr.cipri-tom could you please show the link that you used it to install opencv

Thanks

[cipri-tom]

Sorry, I forgot to include link. I edited my comment to add the link. Note I skipped the virtualenv step, to have it globally installed

[ashirsat]

Is there a way to get it working with opencv 2?

[puku0x]

Hi, @ashirsat

The OpenCV 2.4.9 version is here. https://github.com/puku0x/cvdrone/tree/5e6ffc21e6e6b9b79d632e2991e1270e7f611f02

I hope it helps you.

Hi @puku0x

The installation fails with the same error.

In functionmain': main.cpp:(.text.startup+0x4e2): undefined reference to cv::cvarrToMat(void const*, bool, bool, int, cv::AutoBuffer<double, 136ul>*)' main.cpp:(.text.startup+0x5c3): undefined reference tocv::String::allocate(unsigned long)' main.cpp:(.text.startup+0x5df): undefined reference to cv::imshow(cv::String const&, cv::_InputArray const&)' main.cpp:(.text.startup+0x5e7): undefined reference tocv::String::deallocate()' main.cpp:(.text.startup+0x7e4): undefined reference to cv::String::deallocate()' collect2: error: ld returned 1 exit status make: *** [test.a] Error 1

Would you be able to help me figure out what the issue is ?

Thanks

[puku0x]

Hmm, it seems that your "main.cpp" has an error. @ashirsat, is it the default "main.cpp" ?

[puku0x]

I fixed makefile.

Please try this !

$ sudo apt-get install git
$ cd Desktop
$ git clone https://github.com/puku0x/cvdrone.git

$ sudo apt-get install build-essential
$ sudo apt-get install ffmpeg
$ sudo apt-get install libav-tools
$ sudo apt-get install libopencv-dev

$ cd cvdrone/build/unix 
$ make

[ashirsat]

Cool. I will give it a shot and let you know how that goes.

Thanks a lot for the help.

Hi @puku0x ,

Thanks a ton.

That solved my issue.
