Unable to run a bundle built using the 'mkbundle' command - linux

I am able to build a bundle using the mkbundle command. After that when I try to run the application in another Linux system where Mono is not installed, the application is not executed and there are no errors.

Mkbundle alone will build a binary that still has some dependencies on mono libraries.
If you want to be able to 'just drop your app on any recent Linux box and start it' you should do a static build with mkbundle --static

How do I launch doxygen/perl from Monodevelop on linux/flatpak?

I have a mono-based project that is developed on Linux. Is there some trick to getting custom build steps to run in Monodevelop 7 packaged in flatpak?
The custom build steps that build the doxygen documentation and package it up do not launch. Doxygen and perl are both installed in /usr/bin, and the build steps work properly outside with the legacy monodevelop 5. Doxygen is "not found" and perl runs but is using an (apparently) flatpak builtin /usr/bin/perl that does not have any of the required CPAN modules.
How do I get custom build steps to run in monodevlop 7?
You don't. Flatpak will not run programs that are masked by its packaging, so for example you can not run python or perl scripts that require modules that are not part of the monodevelop flatpak package.
The best solution I can come up with is to launch everything from an external non-cross-platform Makefile, using msbuild for the C# compilation steps. The build does not have to be cross platform, as long as the end product is, so this is a workable, if lame, solution. At least this way you can run the program and debug unit tests in the monodevelop IDE.

How to use appimage to deploy qt5 application

I'm using appimage http://appimage.org to pack my application in a standalone excutable.
I'm doint this on debian testing lenny.
My application uses a lot of opensource libraries (qt, python pythonqt fftw hdf4/5 gsl netpbm qwt) and everything was ok using Qt4. I can compile my app on debian and create an appdir image that run smoothly on mint (with xfce).
This stopped working when I switch to Qt5.
Now the appimage runs on debian, but not on mint, I get this error:
This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: eglfs, kms, linuxfb, minimal, minimalegl, offscreen, xcb.
Reinstalling the application may fix this problem.
Aborted
Notice that the messege is non-consistent: firts it says I lack xcb and than it maks as available.
I did copied the plugins directory in my app usr/lib tree.
I have xcb installed on host apt-get install libx11-xcb1
My AppRun file looks like this:
#!/bin/bash
HERE="$(dirname "$(readlink -f "${0}")")"
cd "${HERE}/usr/"
export LD_LIBRARY_PATH="${HERE}/usr/lib/:${LD_LIBRARY_PATH}"
export PATH="${HERE}/usr/bin:${PATH}"
export QT_PLUGIN_PATH="${HERE}/usr/lib"
exec "${HERE}/usr/bin/Neutrino" "$#"
cd -
What am I missing?
Many Qt5 applications such as Krita, Scribus, and Subsurface are being distributed as AppImages, so it is definitely possible.
Probably you are missing some components that need to be bundled inside the AppImage. Especially, Qt plugins need to be bundled inside the AppImage for it to work.
See here for an example of a Qt5.5 app being packaged as an AppImage.
Note that it is generally recommended to use an old base system such as CentOS 6 for compiling, because the resulting AppImages will be compatible to more distributions rather than just the latest ones.
If you post a link to your project or open an issue on https://github.com/probonopd/AppImages/issues I can possibly give you more detailed directions.

Cocos2d-x linux release build (deploy) doesn't include libraries

I'm quite new to cocos2d-x, so this question may be a bit on the amateur side.
I built a release version of my game using cocos deploy -p linux -m release, found it in the bin folder of my cocos project. I compress it into a tarball, send it to my friend so he can try it in a clean Ubuntu VM. Here's what happened:
Is there a way to include shared libraries in the finished cocos executable or do I have to provide a bash script to install these libraries?

How to make self-contained or java-bundled JavaFX application package for ARM

Where could I acquire a working copy of compiled JavaFX app bundled with JRE so I could execute this app on ARM linux?
or
How can I create my JavaFX app + JRE bundle that would work on ARM Linux
Best case scenario for me would be to be ableto create copy-paste enabled folder tree or single executable file..
I do understand that this question might be too vague, but I desperately need some help on this. I have spent more than 6 evenings + 2 nights searching how to get a compiled JavaFX application ( .jar file) to run on ARM linux on UDOO (RPi2-like) board.
I have been more of an .NET guy a long time, and now I had to make WPF-like rich UX app that would run on this specific hardware, and I chose JavaFX due to its likeliness to WPF. It does run fine on my desktop PCs but I absolutely can not get it to run on ARM linux.
I am trying to do this too. Did you get it working? My solution is to package the JAR using tools provided by IntelliJ or any other IDE, include the JRE in a folder within the app, then write a script that invokes the JAR from the included JRE like:
lib/jre/bin/java -jar runthis.jar
I also tried it for two days now but didn't get it to work.
I use maven in combination with the javafx-maven-plugin to build native installers of an application.
At first I got the error, that the javafx-ant.jar tools are missing:
[ERROR] Failed to execute goal build-jar(create-jfxjar) on project foo:
Execution create-jfxjar of goal build-jar failed: Plugin javafx-maven-plugin or
one of its dependencies could not be resolved: Could not find artifact
javafx-packager:javafx-packager:jar:1.8.0 at specified path
/opt/jdk1.8.0/jre/../lib/ant-javafx.jar
Then I found the ant-javafx.jar in a windows JDK but then another error was reported that linux is not supported with this one. Ok so I downloaded a linux JDK and used that ant-javafx.jar. Now it could build and create a *.deb file successfully!
However when I started the installer it failed with a message and when checking the log (/var/log/apt/term.log)
Log started: 2021-04-29 00:40:01
dpkg: Error creating archive
/home/pi/Foo/target/jfx/native/foo.deb (--unpack):
package architecture (amd64) does not match system (armhf)
Then I did research and found the following mailing list entry:
[...] the Java Packager isn’t shipped with any ARM builds that I’m aware of. Currently it is only for X86 Windows, Linux and Mac. [...]
This basically explains it: The packager doesn't work on ARM for now. Maybe we should write the guy to encurage him to add it...
=> So for now I work with the jar directly.

Missing libc after using mkbundle

I have a C# application developed using mono 3.0.6. Everything works perfectly.
I need to deploy this application to production desktops where I'm not allowed to install mono. So, I decided to use mkbundle, using the command
mkbundle -o myprog --deps --static myprog.exe
On the destination desktop, when I try to execute myprog, it gives me
Unhandled Exception: System.DllNotFoundException: libc
Obviously, both origin and target machines uses the same OpenSuse, except for the fact that target has no mono installed.
What is supposed I'm missing?
TIA.
