Hi Adnan,

Sorry for opening another issue so quickly, but I have a quick question. I have not made modifications to any file after a fresh pull from the ambf-2.0 branch. Upon successfully building the code and sourcing the setup.bash file, I ran into the "JOINT NOT IMPLEMENTED YET" error message whenever I import a multibody object (that contains joints) to the ambf_simulator.

The following is the output I get when typing the bare minimum command: ./ambf_simulator (similar errors show up when I try importing raven or dvrk using the -l flag)

I feel like I must have missed something. Do you have any suggestions?
Thanks a lot!

PS1: There were similar error messages as posed in prior Issues #155 and #159, but the solutions didn't seem to apply in my case.

PS2: I also noticed the warning messages that says "ADF version not defined thus assuming VERSION_1_0". Is that anticipated? Or, should I specify the ADF version in the yaml files somehow. Thanks!

Hi Melody,

Please don't apologize for creating new issues, as a matter of fact, thank you for contributing this way.

The message "ERROR! COMMUNICATION TYPE FOR OBJECT NAMED <name> OF TYPE: JOINT NOT IMPLEMENTED YET" is really a warning, so don't worry about it. I shall change the word "ERROR" to "WARNING" to put people's minds at ease.

The second warning "ADF version not defined thus assuming VERSION_1_0" is also a warning that you can ignore.

The core infrastructure of AMBF-2.0 is entirely different (better) than AMBF-1.0 and these warnings (/ errors) are part of that.

For this comment:

PS1: There were similar error messages as posed in prior Issues #155 and #159, but the solutions didn't seem to apply in my case.

Can you elaborate on what exactly is the issue as these two issues seem to be unrelated? Please feel free to open a new issue, or reopen the existing issues.

Thanks for the quick reply!
It’s great knowing we can ignore the joint type error message and ADF version warning.
In this case, I think the main problem I’m encountering is that after I type in the command:
./ambf_simulator
the program and simulator window shuts itself down right after booting up.

The two previous issues #155 and #159 were ones that I found to have mentioned the same error message, but I see now that those messages are probably not the cause of the simulator shutting down immediately upon starting.

Thanks again! Let me know if there’s anything you suggest that I try.

No problem. Are you running the ambf_simulator with any arguments? Also, can you please provide the output of running ./ambf_simulator in the terminal?

I am not running it with any arguments. Here are the outputs I get on the terminal:

Also here is a quick video showing what I'm seeing (with the simulator window shutting down upon boot). In the video, I also tried loading specific robots with the -l flag, and a similar problem occurred.

Thanks for the video, and I can see that it's a segfault. We shall need to compile AMBF in debug mode and run it via debugger. Can you please try the following steps.

Install gdb(GNU Debugger) if not already installed. You would probably need sudo permissions

sudo apt install gdb

Then build AMBF in debug mode. Assuming that AMBF is located in the home ~/ folder.

cd ~/ambf
mkdir build-debug && cd build-debug
cmake .. -DCMAKE_BUILD_TYPE=Debug
make -j4

After a successful build, head over to the bin-debug folder in AMBF. This folder is created when AMBF is built in Debug mode.

cd ~/ambf/bin-debug/lin-x86_64
gdb ./ambf_simulator

This would launch the gdb console with ambf_simulator. You can then enter different commands to step through the code. We shall be just running it by entering run and pressing ENTER. It should crash and when it does, could you please copy the output and paste it here.

We might also want to try checking the stack trace with valgrind. You can install that by

sudo apt install valgrind

And then run ambf_simulator as

cd ~/ambf/bin-debug/lin-x86_64
valgrind ./ambf_simulator

Valgrind may produce a lot of output but I would be interested in the last part where AMBF crashes.

Hi Adnan,
Thanks for the tips! I tried what you suggested and here is the output I get from gdb.
Specifically, when I typed "r" to run the program, the simulator window popped up; there were nothing displayed on it, but it also didn't shut off on its own. Then to proceed with the program, I typed "c", that's when it shows the last three lines of outputs and shuts down the simulator window.

Awesome, great to have the valgrind output. Can you test something, if you modify this line https://github.com/WPI-AIM/ambf/blob/ambf-2.0/ambf_simulator/src/ambf_simulator.cpp#L343 and change:

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 1);

to

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 2);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 1);

and then recompile AMBF. Does it still crash?

Wow that fixed it! Thank you so much.
Is it because of my laptop having an older version of OpenGL?

Happy to hear that. It is probably not an issue with the OpenGL version itself as version 3.3 and greater have be supported on machines from many years ago.While reading the output from valgrind from your comment, I quickly realized that I accidentally pushed the line glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3) to remote. The rendering methods need to be fixed/updated to work with the newer version of GLFW on all systems. I have not seen it crash on 20.04 but I suppose you are using 18.04, is that correct?

Ah, I see! Yes, the computers in my lab are all 18.04, but I'm currently using my ancient 16.04 laptop. I've renamed the issue title so it's not misleading and will close the comment now. Thanks again for all your help.
