I downloaded vlc-2.2.1 source code and compiled it after a long struggle. Now, when I run it as ./vlc from the source directory, it shows the following error and vlc window does not show up.

I needed the web interface functionality of vlc. So, I configured ~/.config/vlc/vlcrc as

extraintf=http
How can I fix this error ?
NOTE:
I have vlc 2.1.6 installed in my computer,
it works fine

I'm not using NixOS but I wrote a flake that I'm using to generate a dev shell to build a Rust project (this is essentially just the audio example from the Bevy repository). My issue is that I encounter the following error when attempting to run the project in the dev shell:
$ nix --extra-experimental-features nix-command --extra-experimental-features flakes develop
bash-4.4$ cargo run
Finished dev [unoptimized + debuginfo] target(s) in 6.62s

-0.5.0/src/audio_output.rs:22:67
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
bash-4.4
One of the dependencies of the project is the Bevy crate which requires ALSA, so I'm assuming the issue is because the ALSA package exposed by the dev shell is probably misconfigured. I use PipeWire on my actual system (I think it also uses ALSA as a backend) and I tried adding ALSA and PipeWire as one of the buildInputs for the flake, but I'm not sure how I'm supposed to configure these within the dev shell. According to this issue on the Bevy repository, the usual fix for this issue, at least for Arch-based distros, is to install the pipewire-alsa package. I'm not sure what the equivalent of doing that is in the context of a Nix dev shell is though, since there is no pipewire-alsa package in nixpkgs that I can add to my flake. So with that said, how should I go about configuring ALSA or PipeWire in the dev shell?
I am using ROS Melodic on Ubuntu 18.04 with gazebo9 and Xlaunch. I have been able to launch an empty workspace of gazebo but for some reason when I run rosrun rviz rviz, I get this error message:
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.
I have roscore running with no errors, so I dont believe its that which is causing the problem

Since WSL runs on top of the windows hypervisor you should treat the terminal like it has no direct knowledge of your display. To get this to work you need to do 2 things.
You need to download a windows X Server client. I personally use XMing.
Set your environment variable DISPLAY. Such as export DISPLAY=localhost:0.0
Edit: After doing some digging this issue is caused by how libGL interacts with the specific x server you're running. You have two options to fix this:
You run XMing instead of of XLaunch
If you want to keep using XLaunch under the "Additional Parameters for VcXsrv" add -nowgl
For me the solution was as simple as updating my WSL2 (Run Linux GUI apps on the Windows Subsystem for Linux)

Where could I be going wrong?
EDIT
Now this is confusing...
When I ran 'Send Android build' when my PC is connected to internet, it gives that message I posted before.
So accidentally, I ran 'Send Android build' while my PC was offline and it passed that point and it showed me this pop up:
Now.. once I this pop-up shows, that's when I connect to internet and everything will flow as supposed to.
So its like, if I have internet connected right from the start, it isn't successful but if I connect to internet after showing me the popup of an invalid Android certificate, everything will work fine and the build will be in the build server.
But is causing this now?
I'm trying to debug code as it runs on my Android test device. I sent a build to the CN1 server and downloaded the resulting sources.zip, which I then used to create a project in Android Developer Studio.
When I compile using
Compile SDK Version: API21 or API 22 with
Build Tools Version: 21.1.2 or 22.0.1, respectively
I get the following compile errors:
C:\home\dev\ProxyServerDebug\build\intermediates\res\merged\debug\values-v23\values-v23.xml
Error:(3) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'.
Error:(18) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'.

> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\opt\android-sdk\build-tools\22.0.1\aapt.exe'' finished with non-zero exit value 1
When I compile using
Compile SDK Version: API 23
Build Tools Version: 23.0.2
I get the following compile errors:
C:\home\dev\ProxyServerDebug\src\main\java\com\codename1\impl\android\AndroidImplementation.java
Error:(4563, 21) error: cannot find symbol method setLatestEventInfo(Activity,String,String,PendingIntent)
C:\home\dev\ProxyServerDebug\src\main\java\com\codename1\impl\android\PushNotificationService.java
Error:(110, 18) error: cannot find symbol method setLatestEventInfo(PushNotificationService,String,String,PendingIntent)
Is it just a matter of setting the correct SDK and Build Tools versions? or am I missing something else? BTW, sources were generated this morning, so I should be on the latest CN1 3.3 release.
If I recall correctly it should be 22.0.1 the reason build fails by default is that you need to configure an external gradle directory as explained in How to build the native Android sources from Codename One's build server
When trying to build ios client in react-native, I modified part of AppDelegate.m file as shown below (i.e., replaced option 1 with option 2):
// OPTION 1
// Load from development server. Start the server from the repository root:
//
// $ npm start
//
// To run on device, change `localhost` to the IP address of your computer, and make sure your computer and
// iOS device are on the same Wi-Fi network.
//jsCodeLocation = [NSURL URLWithString:#"http://localhost:8081/index.ios.bundle"];
// OPTION 2
// Load from pre-bundled file on disk. To re-generate the static bundle, run
//
// $ curl http://localhost:8081/index.ios.bundle -o main.jsbundle
//
// and uncomment the next following line
jsCodeLocation = [[NSBundle mainBundle] URLForResource:#"main" withExtension:#"jsbundle"];
I downloaded main.jsbundle to the iOS folder where AppDelegate.m is.
$ ls iOS
AppDelegate.h Base.lproj Info.plist main.m
AppDelegate.m Images.xcassets main.jsbundle
But, if I do the build again in XCode and run it in ios simulator, it pauses in main.m with the following error:
2015-03-31 12:46:28.877 AwesomeProject[26849:1320518] * Assertion

So, it seems to be complaining about bundleURL. I will appreciate help with identifying what the issue is.
You need to add the file to the project.
To do so, you need to right-click on the project name and select "Add files to MyProject…". Then choose the main.jsbundle.
Then build your project and it should work.
