My QGroundControl window shows nothing but darkness in WSL2. When I launched it, I got the following messages and in the application nothing was shown but darkness.

Do you guys have the same problem and know how to solve it? Thanks!

I want to use Intel QSV in WSL2.
Based on the experience of using QSV on a native Ubuntu PC, I installed the same library, but it doesn't work.
ex) ffmpeg, libva, vainfo, intel Media SDK, gmmlib, media-driver ...
My CPU supports QSV, but I can't initialize it.
In vainfo it works like this:
$ ls /dev/dri
card0 renderD128
$ sudo vainfo
Trying display: wayland
error: XDG_RUNTIME_DIR not set in the environment.
Trying display: x11

libva info: Found init function __vaDriverInit_1_14

libva error: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so init failed
libva info: va_openDriver() returns 18

I want WSL to be initialized properly so I can use it in C.
Try changing the libva driver to i965 if it solves the error, Your error logs shows the call to i965 driver instead of iHD.
DRM_IOCTL_I915_GEM_APERTURE failed: Invalid argument

I'm running puppet 2.7.26 because that's what the redhat package provides.
I'm trying to serve files that are NOT stored within any puppet modules. The files are maintained in another location on the puppet server, and that is where I need to serve them from.
I have this in my /etc/puppet/fileserver.conf
[files]
path /var/www/cobbler/pub
allow *
And then I have a class file like this:
class etchostfile
(
$hostfile /* declare that this class has one parameter */
)
{
File
{
owner => 'root',
group => 'root',
mode => '0644',
}
file { $hostfile :
ensure => file,
source => "puppet:///files/hosts-${hostfile}.txt",
path => '/root/hosts',
}
}
But when my node calls
class { 'etchostfile' :
hostfile => foo,
}
I get this error
err: /Stage[main]/Etchostfile/File[foo]: Could not evaluate: Error 400
on SERVER: Not authorized to call find on
/file_metadata/files/hosts-foo.txt with {:links=>"manage"} Could not

SERVER: Not authorized to call find on
/file_metadata/files/hosts-foo.txt with {:links=>"manage"} at
/etc/puppet/modules/etchostfile/manifests/init.pp:27
This post
https://viewsby.wordpress.com/2013/04/05/puppet-error-400-on-server-not-authorized-to-call-find/
indicates that this is all I need to do. But I must be missing something.
UPDATE
When I run the master in debug mode, I get no error.
The master responds thusly:

notice: Finished catalog run in 0.42 seconds
and the file is properly installed/updated.
So it works when the master is in debug mode, but it errors when the master is in standard (?) mode. I can go back and forth, in and out of debug mode at will, and it works every time in debug mode, and it fails every time in standard mode.
UPDATE 2
Running puppetmasterd from the command line, and everything works.
Running service puppetmaster start or /etc/init.d/puppetmaster start from the command line, and it fails. So at least I'm getting closer.
/etc/sysconfig/puppetmaster is entirely commented out. So as of now, I do not see any difference between just starting puppetmasterd and using the service script.
UPDATE 3
I think it's an SELinux problem.
With SELinux "enforcing" on the master, service puppetmaster restart, and I get the error.
I change SELinux to "Permissive" on the master, and I still get the error.
But now that SELinux is set to Permissive, if I service puppetmaster restart, my files get served properly.
But now that it's working, I set SELinux to Enforcing, and I get a different error:
err: /Stage[main]/Etchostfile/File[foo]: Could not evaluate: Could not
retrieve information from environment production source(s)
puppet:///files/hosts-foo.txt at
/etc/puppet/modules/etchostfile/manifests/init.pp:27
Then I do a service puppetmaster restart and I'm back to the original error.
So the situation changes depending on
how I started the service (puppetmasterd or service)
what SELinux was set to when I started the service
what SELinux is set to when the agent runs.
The closer I get, the more confused I get.
UPDATE 4
I think I found it. Once I started looking at SELinux, I found the policy changes I needed to make (allowing ruby/puppet to access cobbler files) and now it appears to be working...
This turned out to be an SELinux problem. I eventually found this error message
SELinux is preventing /usr/bin/ruby from read access
on the file /var/www/cobbler/pub/hosts-foo.txt .
which led me to the audit2allow rules I needed to apply to allow puppet to access my cobbler files.
I was getting this error with puppet server on ubuntu 20.
Error: /Stage[main]/Dvod_tocr/File[/install/wine-data.tar.gz]: Could not evaluate: Could not retrieve file metadata for puppet:///extra_files/wine-data.tar.gz: Error 500 on SERVER: Server Error: Not authorized to call find on /file_metadata/extra_files/wine-data.tar.gz with {:rest=>"extra_files/wine-data.tar.gz", :links=>"manage", :checksum_type=>"sha256", :source_permissions=>"ignore"}
My fileserver.conf file was in the wrong location. The correct location for this puppet version and on ubuntu 20 is /etc/puppetlabs/puppet/fileserver.conf

I'm trying to install OpenCV-2.4.9 on CentOS 7 (PC) however getting error after 16% when running "make" command. I leave default configuration for OpenCV.
make

It seems that the define HAVE_CAMV4L has the value 1, if you look in the file modules/highgui/src/cap_v4l.cpp looking for the structure definition at the row 306. If the compilation fails at that point this means that the video4linux development configuration is corrupted.
Using google I have found that the OpenCV Bug #1357 is described as follow:
CHECK_INCLUDE_FILE(linux/videodev.h HAVE_CAMV4L) succeeds even though linux/videodev.h doesn't exist on the system. (Bug #1357)
http://code.opencv.org/issues/1357
Anyway the solution is described at the same URL for "HAVE_CAMV4L gets set incorrectly": "Setting it to FALSE in CMakeLists.txt fixes the problem".
I tried to play with overtone on ubuntu, but I can't eval some of overtone's codes in Vim.
:Eval works for the clojure code; I tried it in vim (a clj file in the lein project directory), ex: (+ 1 2 3) => :Eval => appeared on the bottom of the vim window => 6, so it's ok.
But, for example, I tried:
(demo(sin-osc)) => :Eval ;(:Require don't change nothing)
It returned:
java.lang.RuntimeException: Unable to resolve symbol: demo in this context, comp
iling:(NO_SOURCE_PATH:1:1)
So here's what I do:
jack is started
lein repl is started in the lein project (deps is ok)
in the first terminal where there is lein I start overtone (use 'overtone.live), here is the log; I've got 2 errors:
user=> (use 'overtone.live)
--> Loading Overtone...
--> Booting internal SuperCollider server...
* ERROR: dlsym load err '/home/axxon/workspace/overtone/tutorial/native/linux/x86_64/libscsynth.so: undefined symbol: load'

SC_AudioDriver: sample rate = 44100,000000, driver's block size = 1024

here, in this window I tried (demo(sin-osc)). it works; I can hear it.
Great, but now I want to script with Vim, so I created a new file (mytest.clj) in the lein project directory (/overtone/tutorial), I opened it with Vim (in another window)
in this blank file, I wrote the same thing as I said before, (demo(sin-osc)) and tried to eval with first, :Require, it returned this:
(clojure.core/require 'user :reload)
java.io.FileNotFoundException: Could not locate user__init.class or user.clj on
classpath:
with Eval, it doesn't work either.
Thanks for your help because I really want to use overtone!
Ps: my vim bundles:
Bundle 'guns/vim-clojure-static'
Bundle 'tpope/vim-fireplace'
Bundle 'tpope/vim-classpath'
Edit: I forgot to use a correct namespace, and in overtone's google group, i seen that mytest.clj must be in the src directory of the project. I tried this code with :Require (i stopped overtone in the first window where i started lein):
(ns tutorial.foo
(:use [overtone.live]))
(definst saw-wave [freq 440 attack 0.01 sustain 0.4 release 0.1 vol 0.4]
(* (env-gen (lin-env attack sustain release) 1 1 0 1 FREE) (saw freq) vol))
(saw-wave)
, but it returned:
(clojure.core/require 'tutorial.foo :reload)

I was having the same problem. It turned out that the vim fireplace plugin was not connected to my bash repl session. I manually established the connection and everything worked just fine afterwards.
At the top of your lein session you should see the details about what port the repl session is running on
nREPL server started on port 35182 on host 127.0.0.1
So then you can connect vim-fireplace to that repl session by using
:Connect nrepl://localhost:35182
The reason why you can still evaluate code like (+ 1 2 3) even when vim-fireplace is not connected to the remote repl session is because vim-classpath will make it fall back to just spawning a new clojure runtime instance to evaluate that code. Once the fireplace repl connection is working you should notice that evaluating code becomes a lot faster since it doesn't need to load clojure from scratch.
Make sure that you use overtone.live in the namespace declaration of the file you are editing in vim, and that the REPL is running in a separate terminal instance. From vim, save the file (:w) and move your cursor into the ns declaration. Then hit gf to open the file for the namespace. Type cpR or :Require! and then cpp or :Eval the function you were trying to run. Hopefully this will work for you! Best of luck.
