Bus Error (core dumped) Ubuntu 18.04

[arasharchor]

Hi
I am going to try your annotation tool during my studies. I am using a ubuntu 18.04 with OpenCV 4.0

Could you please let me know what could be the reason for this issue?

If there is a version mismatch, is it possible to share the source code that I will adapt it to the versions which I have installed in my machine?

Thanks for your interest. The is mainly because of the version issues. You can try the following ways: （1）install Ubuntu 14.04 or 16.04 64bit， （2） if you don't want to reinstall the system. we suggest to try to recompile the whole project by yourself. First, change the Makefile line 17 to："$(lnk) $(dbg) -o bylabel $(objRRC) pkg-config --libs opencv EDLib.a EDLinesLib.a", then，compile the project by command "make". Before that you may have to make sure that your installed opencv version is greater than 2.4.9 and also QT=enable when opencv was installing, otherwise you may not able to zoom in/out the image by your mouse middle button.

I try to "make" the code. However, errors is shown as follow

g++ -g -Wall -o bylabel bylabel.o -fPIC pkg-config --libs opencv EDLib.a EDLinesLib.a

Could you please help to compile a version for 18.04 user? Thank you.

I have the same error.

Ubuntu 18

/usr/local/include/opencv2/core/cvstd.inl.hpp:81: referencia a `cv::String::allocate(unsigned long)' sin definir
collect2: error: ld returned 1 exit status
make: *** [Makefile:17: bylabel] Error 1

Any solution for this?
