I am using instant veins with simulte, I created my own scenario that includes vehicles and pedestrians.
When I tried to run my simulation, I got this error:
Attempted to read past end of byte buffer -- in module ( veins::VeinsInetManager)
I don't think that is related to a sumo and veins versions' compatibility because sumo is preinstalled in the virtual machine instant veins, but I tried export SUMO_HOME ="$PWD/sumo" and it doesn't work.
Can you help me, please?
I faced the same problem. After adding following code in configuration file (sumo.cfg), it is fixed.

I want to learn Qt especially for the 3D functionalities and therefore was following this tutorial.
One part of the tutorial is displaying the mesh from a .dae file called object.dae.
When I tried to run my code for the first time, I got the following error:
2:25:52: Starting /home/qt/build-Qt3DTests-Desktop_Qt_5_15_2_GCC_64bit-Debug/Qt3DTests ...
Qt3D.Renderer.SceneLoaders: Qt3DCore::QEntity* Qt3DRender::Render::LoadSceneJob::tryLoadScene(Qt3DRender::QSceneLoader::Status&, const QStringList&, const std::function<void(Qt3DRender::QSceneImporter*)>&) Found no suitable importer plugin for QUrl("file:../Qt3DTests/Models/object1.dae")
22:26:00: /home/qt/build-Qt3DTests-Desktop_Qt_5_15_2_GCC_64bit-Debug/Qt3DTests exited with code 0
I proceeded to clone the repo (tag: STEP_001) and try running it but again I receive the same error.
As this was the first Qt tutorial and C++ code I ever did, I am unsure what could be the problem. Does anybody know what is going wrong? Am I missing some module in my installation or something?
The cause might be this (rare) bug in Qt:
https://bugreports.qt.io/browse/QTBUG-89045
I am doing the Pintos project on the side to learn more about operating systems. I had tons of devops trouble at first with it not running well on an 18.04 Ubuntu droplet. I am now running it on the VirtualBox image that UCCS tells students to download for pintos.
I finished project 1 and started to map out my solution to project 2. Following the instructions to create a file I ran
pintos-mkdisk filesys.dsk --filesys-size=2
pintos -- -f -q
but am getting error
Kernel PANIC at ../../threads/vaddr.h:87 in vtop(): assertion
`is_kernel_vaddr (vaddr)' failed.
I then tried running make check (all the tests). They are all failing for the same reason.
Am I missing something? Is there something I need to implement to fix this? I reread the instructions and didnt see anything?
Would appreciate help!
Thanks
I had a similar problem. My code for Project 1 ran fine, but I could not format the filesystem for Project 2.
The failure for me came from the following call chain:
thread_init() -> ... -> thread_schedule_tail() -> process_activate() -> pagedir_activate() -> vtop()
The problem is that init_page_dir is still NULL when pagedir_activate() is called. init_page_dir should have been initialized in paging_init() but this is called after thread_init().
The root cause was that my scheduler was being called too early, i.e. before the call to thread_start(). The reason for my problem was that I had built in a call to thread_yield() upon completion of every call to lock_release() which makes sense from a priority donation standpoint. Unfortunately, locks are used prior to the scheduler being ready! To fix this, I installed a flag called threading_started that bails in the first line of my thread_block() and thread_yield() functions if thread_start() has not yet been called.
Good luck!
I'm working on a small weather station and yesterday everything was working well. This morning I changed some code and suddenly this came up when I wanted to upload the code to my Adafruit:

An error occurred while uploading the sketch
Even simple code won't upload anymore. Could someone help me with this? I tried so many things already and I can't figure it out.
Thanks.
I had the same problem with my Adafruit Feather M0. I opened the platform.txt file (running Wordpad as an administrator) located at
C:\Users\[yourPC]\AppData\Local\Arduino15\packages\adafruit\hardware\samd\1.2.9\platform.txt
and changed the line
tools.bossac.path={runtime.tools.bossac-1.7.0.path}
to reflect the actual path of the bossac.exe file (mine was at)
C:\Users\[yourPC]\AppData\Local\Arduino15\packages\adafruit\hardware\samd\1.2.9\tools\
After restarting Arduino, I was finally able to upload a sketch to my M0.
I have been experiencing the same issue. I found that if I went to my Board Manager and downgraded my Feather boards from 1.6.18 to 1.6.17 it fixed the problem.
java.io.IOException: Cannot run program "{runtime.tools.bossac-
1.7.0.path}/bossac": CreateProcess error=2, The system cannot find the file
specified
The above line says the path to bossac.exe command line application for ATSAMD micro was not found.
Simply Goto --> C:\Users[yourPCnamehere]\AppData\Local\Arduino15\packages\arduino\tools\bossac
Did you find bossac.exe file there?
If not then that's the problem. Simply uninstall the Arduino from your PC and delete the above directory Arduino15 if you have an offline copy of Arduino and then install new version. bossac.exe tool will come with the Arduino package.
Please try this and see if it helps.
I'm trying to add torrents to transmission from python. The code is shown below...
def download_movie(magnet_link):
os.system('transmission-gtk')
#webbrowser.open(magnet_link)
os.system('transmission-gtk ' + magnet_link)
As you can see I've tried 3 different options to add these torrents but none work.. I've also added XDG_RUNTIME_DIR="/run/user/1000" in the crontab file. The log in /var/mail is running the script but it shows: (transmission-gtk:14091): Gtk-WARNING **: cannot open display:. I've also run the command xhost + as said in http://www.thegeekstuff.com/2010/06/xhost-cannot-open-display/ but still the gtk-warning comes up. Anyone have any ideas? What I want eventually is that I run this script on a pi so if anyone has any alternatives, I'm all ears.. Thanks.
It's because you are trying to use GUI app where console one would be appropriate.
See man transmission-remote for details:
DESCRIPTION
transmission-remote is a remote control utility for transmission(1) and transmission-daemon(1).
I want to include Statistics::R for my program.
The statement I am including is:
use Statistics::R;
Is there something wrong with it?
I tried to run it with just this statement included, the error i got was
Can't locate Statistics/R.pm in #INC(#INC contains: /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at rperl.pl line 2
By the way I am using perl(v5.14.2) on ubuntu,using remote access to a linux server.
The solution was to install the module as non-root user.
The details are provided in the following link:
http://users.soe.ucsc.edu/~you/notes/perl-module-install.html
After doing the things described here, a couple of small steps are to be completed which are mentioned in the following link:
http://perlmaven.com/how-to-change-inc-to-find-perl-modules-in-non-standard-locations
This worked for me! I hope it would be of help to others too!
