Error:
<PATH_TO_SUMO>/bin/netedit: symbol lookup error: /usr/lib/libgdal.so.20: undefined symbol: ecs_SetReportErrorFunction
This error appears when I try to run netedit. I have both the Webots simulation software, as well as the SUMO simulation software in my system and both, have netedit. When I remove either one of the software and then run netedit, it works. So, I think the issue is because of the presence of netedit twice. I was running netedit directly from the terminal but even after I give the exact path of the netedit I want to run, in a python script, and then run that script(For eg: I give the path of the netedit in SUMO), it shows this error. How to force the system to use a particular netedit (either webots' or SUMO's) whenever the netedit command is given?
This should be a question of setting your environment variable(s) PATH (and possibly LD_LIBRARY_PATH) to the correct values. If you install SUMO via the package manager of your Linux (apt or something) there should be nothing to adapt. I see from the Webots docs that they recommend manual adaption of those paths. If you don't do those changes or revert them you should be always using the netedit coming with plain SUMO. If you want to use the Webots version adapt the paths such that they list Webots directories first.

I found this repo with a systemtap script for letting me use QWERTY ctrl-shortcuts on my dvorak layout. Unfortunately, I can't get it to work, but I don't think it has to do with the script itself. I'm running Pop OS and I think that it's because the linux-image I need with all the debug symbols doesn't exist.
The script says I need to install linux-headers-$(uname -r) linux-image-$(uname -r)-dbg
For me, this turns into linux-headers-5.11.0-7620-generic linux-image-5.11.0-7620-generic-dbg
linux-headers-5.11.0-7620-generic exists and I'm able to download it using apt-get.
linux-image-5.11.0-7620-generic-dbg can't be installed using apt-get. I can install
linux-image-5.11.0-7620-generic, but that's not the same thing. I've spent time looking online for it and adding different keys to apt-get, but I haven't been able to find anything with that name. If the problem is not having the correct linux-image package installed, I need help being pointed in the right direction as to where I can get it.
I tried following the directions here, and I've also searched this to no avail. I tried downloading and installing linux-image-4.4.0-142-generic-dbgsym_4.4.0-142.168_amd64.ddeb but that also didn't work.
If this isn't the problem, I've provided the output of the script. Any help is appreciated.

Tip: /usr/share/doc/systemtap/README.Debian should help you get started.
Yes, debuginfo downloading has been a pain on many distros. However, if you're running Debian kernels, see: https://wiki.debian.org/Debuginfod for instructions on using a new automated system. Generally: https://sourceware.org/elfutils/Debuginfod.html .
I was running across this piece of documentation: https://cmake.org/cmake/help/v3.13/manual/cmake-server.7.html
But as it turns out, the description given on how to start the server, is not the same as shown in the documentation. When executing cmake -E server --debug, I am getting the following message:
CMake Error: No protocol versions defined. Maybe you need --experimental?
When adding the suggested flag --experimental, the server will launch, reading from standard input and responding to standard output, as expected. However, all the examples shown on the documentation do not suggest the use of this flag. Plus, I have version 3.13.4 installed as well.
What is the proper way of starting the CMake server, as in how would I specify the protocol version, and why am I asked to use --experimental?
My main goal is to find out if I can extract values like targets and their associated information (like CFLAGS) off CMake. Using this server command would certainly let me do this by just writing a small piece of NodeJS code to interact with it.
Problem when calling netconvert in sumo:
I am trying to create my own scenario for simulation purposes.
I am using OpenStreetMaps for this.
python osmWebWizard.py
opens the browser and I select the area which I download.
netconvert --osm-files osm_bbox.osm.xml -o osm.net.xml
The error message I get is
Error: Cannot import network data without PROJ-Library. Please install packages proj before building sumo
Warning: Environment variable SUMO_HOME is not set, using built in type maps.
Quitting (on error).
My attempt to fix the problem is:
sudo apt-get install libproj*
But it seems like a dead end there and I am out of options.
Thank you.
EDIT
I have a gut feeling it has to do with libproj0 not being available anymore.
I was given a fairly large program to compile and run with extremely vague instructions on how to properly configure my system and install the program. I was told to use a Windows, install Cygwin, navigate to the program's base directory, and type "make". I installed Cygwin on a 64-bit Windows 7 in C:\cygwin64 as the main user (I also installed all of the default packages, plus a few extras) and then ran the makefile included with the program (this worked with no problems). When trying to run the executable with a required file argument, I was simply given the error message "cannot connect to X server." Upon examination of the code, it appears that this error was caused by a line setting display=XOpenDisplay(NULL) and then exiting when this resulted in display == NULL. Earlier, "display" had been declared as a variable of type Display. Is there any way I can get the program to connect to the X server? I have been assured that the installation of the program is extremely easy, but I'm not so sure... Thanks in advance.
I have installed PyDev successfully, I have python 3.4.0 installed successfully and the folder containing python.exe is in my path and I can run it from the command line.
However, when I go to window\preferences\pydev\interpreters\python interpreter and select 'quick auto-config' to configure it using normal python I get an error saying 'auto configurator could not find a valid interpreter... Note the system environment variables used for Jython are PATH and PYTHONHOME.'
Unless this is a bug in the text I am not selecting Jython (I get a different error if I select IronPython, btw, so this is not a generic error message).
The trace is as follows:
Errors getting info on discovered interpreter(s).
See error log for details.
java.lang.RuntimeException: java.io.IOException: Cannot run program "python": CreateProcess error=2, The system cannot find the file specified
As I say, python.exe is in my path.
You have to install the actual python package separately from here https://www.python.org/download
Close LiClipse/Eclipse => Download Python Here: https://www.python.org/download
=> reopen LiClipse => Auto Config for the interpreter Will WORK!
I found the answer, but I'll leave this up in case anyone else gets it. It's a pretty stupid auto config option if you ask me ;)
In the higher level window\preferences\pydev\interpreters\ preference you need to untick jython and ironpython.
No idea why given I selected the Python sub-preference specifically.
