IMPORTANT: Please use the following template to report the bug.

Describe the bug
A clear and concise description of what the bug is.
set fault when drawing geometry
To Reproduce
Steps to reproduce the behavior:
code:

#include <iostream>
#include <memory>
#include <thread>

#include <open3d/Open3D.h>

// A simplified version of examples/Cpp/Visualizer.cpp to demonstrate linking
// an external project to Open3D.
int main(int argc, char *argv[]) {
    using namespace open3d;


        auto cloud_ptr = std::make_shared<geometry::PointCloud>();
      io::ReadPointCloud("/path/to/pcd.pcd", *cloud_ptr);

        cloud_ptr->NormalizeNormals();
        std::cout << cloud_ptr->points_.size() << std::endl;
        visualization::DrawGeometries({cloud_ptr}, "PointCloud", 1600, 900);


    return 0;
}

Expected behavior
nice geometry,

in python works though...

Environment (please complete the following information):

  • Operating system: ubuntu 18.04
  • Open3D version: 0.10.1 (tip of master)
  • Is this remote workstation?: yes or no
  • How did you install Open3D?: build from source with abi = 1
  • Compiler version (if built from source): gcc 9

Additional context
Add any other context about the problem here.

Thanks @femust ! This is good information. Thanks @nachovizzo for confirming that disabling gui avoids the segfault.
There seems to be something wrong with linking OpenGL when the GUI is enabled.
I am still trying to reproduce this issue.

Hi @femust , can you compile open3d in Debug mode to get more information?

benjaminum picture benjaminum on 28 Jul 2020

Yes, I saw your previous post and I compiled in debug mode as well, BUT I had the same information, so successfully loaded, but when visualizing seg fault

femust picture femust on 28 Jul 2020

@benjaminum funny enough is that the visualization works when I use python (installed via pip install ), but when I use cpp then seg fault

@benjaminum funny enough is that the visualization works when I use python (installed via pip install ), but when I use cpp then seg fault

Just to get an overview of the configurations:

  • Visualization fails when compiling from source and creating a C++ binary linking open3d.
  • Visualization works when installing the package from PyPI

Is this correct?

Does the visualization work with the python package compiled from source? (make install-pip-package)

Can you get more information about the segfault with a debugger?
If you have gdb the following will print some parts of the stack

gdb -ex run -ex bt -ex li -ex up -ex li -ex up -ex li -ex up -ex li -ex quit ./binary_that_causes_segfault

@benjaminum Yes you are correct, after gdb I have something like this:

Quit anyway? (y or n) y
femust picture femust on 30 Jul 2020

@femust Can you check if you have compiled open3d in Debug mode (can be enabled during configure with cmake .. -DCMAKE_BUILD_TYPE=Debug)
This could help to better pinpoint the instruction that is failing.

@benjaminum right, i came back to the release mode for some weird reason, sorry for that. So once again:

it looks a bit like openGL problem...

Yes, looks like a problem with opengl. Can you also provide the information from glxinfo and the libraries you link to with ldd your_binary?

the project itself I'm linking with ${Open3d_libraries} since it's just a "hello world" for point cloud visualization

femust picture femust on 31 Jul 2020

The glxinfo seems fine. I don't see how glEnable(GL_DEPTH_TEST) can cause this problem. It is also weird that visualization works for you from python. So I wonder if there is a difference in the libraries loaded. Can you do ldd on the binary and on the open3d python module just to be sure? You can get the location of the python module with
python -c "import open3d; print(open3d.pybind.__file__)"

With this open3d.pybind, I get that:

AttributeError: module 'open3d' has no attribute 'pybind'

maybe because I installed from pip? But honestly, I tried to install with pybind right now and I get the same error (with python3 ofc)

femust picture femust on 2 Aug 2020

Sorry, I was assuming the version in the master branch. This should work for the pip package from PyPI
python -c "import open3d; print(open3d.open3d_pybind.__file__)"

here we go: 

/home/andrzej/.local/lib/python3.6/site-packages/open3d/open3d_pybind.cpython-36m-x86_64-linux-gnu.so
femust picture femust on 2 Aug 2020

Can you run ldd on this file to see if there is a difference between the loaded libraries?

benjaminum picture benjaminum on 2 Aug 2020

so actually after ldd ./my_file.py i got

    not a dynamic executable

I read that it may be caused by a 32-bit lib version installed on 64 bit? But I think it's quite impossible since I installed by pip

femust picture femust on 2 Aug 2020

You can run ldd directly on the .so file.
Try ldd /home/andrzej/.local/lib/python3.6/site-packages/open3d/open3d_pybind.cpython-36m-x86_64-linux-gnu.so

so python file doesn't link opengl at all ? (not sure whether this libGL is connected somehow with opengl?)

femust picture femust on 2 Aug 2020

No, the python file itself does not link anything. The C modules imported in the python file will load libraries. open3d_pybind.cpython-36m-x86_64-linux-gnu.so is such a C module.

Thanks for the information.
The paths to the GL libs are the same for the binary and the C module, which means there isn't a problem with using different OpenGL implementations.
However, the binary links libOpenGL.so and libGL.so while the C module just links libGL.so. I am not sure if it is OK to link both as they probably implement almost the same functions. I have to do some research on this.

benjaminum picture benjaminum on 2 Aug 2020

Hmm I tried also rename libOpenGL as libOpenGL.bak because I thought that maybe the things from libGL.so will be enough, but then during compilation, I have a linking problem, that the lib hasn't been found etc.

Ok so if you learn something valuable, please let me know

While I build open3d in build/bin folder there is something like ViewGeometry, and when I try to run it with a point cloud as an argument it runs, ldd info is:

femust picture femust on 3 Aug 2020

So linking libOpenGL.so and libGL.so really seems to be the culprit here. I asked a colleague for help on this problem. Meanwhile, can you give the cmake version you are using?

benjaminum picture benjaminum on 3 Aug 2020

after
cmake --version

cmake version 3.17.3
CMake suite maintained and supported by Kitware (kitware.com/cmake).

but as far as i remember open3d supports from 3.12 so it should be fine

femust picture femust on 3 Aug 2020

@benjaminum
so when I compiled with 

cmake -DENABLE_GUI=OFF ..

seg fault disappeared

femust picture femust on 5 Aug 2020

Thanks @femust ! This is good information. Thanks @nachovizzo for confirming that disabling gui avoids the segfault.
There seems to be something wrong with linking OpenGL when the GUI is enabled.
I am still trying to reproduce this issue.

benjaminum picture benjaminum on 5 Aug 2020

@femust, @nachovizzo do you use machines with multiple GPUs/drivers, e.g., a laptop with integrated + discrete gpu from different vendors?

benjaminum picture benjaminum on 6 Aug 2020

@benjaminum I faced the error in 2 computers, 1 with 1 NVIDIA GPU and the other with NO GPU

nachovizzo picture nachovizzo on 6 Aug 2020

@benjaminum laptop with gpu

femust picture femust on 7 Aug 2020

Unfortunately, we cannot reproduce this issue, which makes this very difficult to debug.
@femust @nachovizzo would you be willing to help us to further debug this?

benjaminum picture benjaminum on 12 Aug 2020

@benjaminum yes, let me know how can I help you

femust picture femust on 12 Aug 2020

Can you attach the link information from cmake? You can get all the relevant files with find cpp -name "*link.txt" in the build directory.

benjaminum picture benjaminum on 13 Aug 2020

Hi @femust , there have been many changes and a new release since this issue was opened.
Please reopen this issue if the problem still persists with the latest version.
