trying to use rapagui on linux... executable won't start

I'm on Ubuntu and trying to write a game that uses rapagui, and when compiling it it says it is successful and in the log I see it is saying it was able to find rapagui.hwp. But when I run the executable it pops a window saying that rapagui.hwp is required.
What did I do wrong? As I said it says it found and loaded rapagui.hwp at compile time and in HollywoodGUI it lists the rapagui examples etc.
Thanks!

Did you place RapaGUI in the directory of the executable? If so, is it really the correct version (32-bit or 64-bit must match too)?
You can also link a plugin to the executable, but this may cause licensing issues. Please read the
Linking plugins section in the manual.

Yes I belive I placed it in there. As I said it loads the plugin when compiling my game, and thos is the only plugin I am using so licensing should not be a issue. I read that link before but from what I could see there is only one folder for Linux, not all of the linux platforms supported in Hollywood.

RapaGUI on Linux is a bit more complicated because there are four different builds (GTK2, GTK2+webview, GTK3, GTK3+webview). My guess is that you've linked a webview build of RapaGUI to the executable but gtk-webview isn't installed on your system. To see why RapaGUI fails loading, you have to install Hollywood and RapaGUI on your Linux system and start it from a terminal. If it fails to load RapaGUI, it will print some info on why it couldn't be loaded to the console, typically because some components are missing on the Linux system.

I have the same exact problem.. I am not able to display the demos of Rapagui..
I would like to know, talking about the plugins copyright and GPL licence, what happen if I realize a program with rapagui (a cms program) and I include the plugin in the program in a proper directory called "Plugins" so that the required plugin is included together with the program and so it is not statically linked to the exe? is it legal?

On Linux things are more difficult than on other platforms given the wide variety of distributions so to make an educated guess I need to know the following: What Linux distribution and version are you on? What desktop environment (GNOME, KDE...)? Which GTK version is installed?
For the best compatibility I recommend using the x64-linux-gtk3 flavour because the -webview flavour depends on an external component which is often not installed by default. Have you tried x64-linux-gtk3?

First of all thanks for the reply Andreas
I am using Debian 12 with KDE. I deleted my previous installation of Hollywood and reinstalled everything from scratch, installing only RapaGUI as plugin, and I installed, as you suggested, the GTK-3 version but nothing changed.. If try to compile a project, it tells me that the project is compiled but in the log file I found the error about Rapagui.. But Rapagui is available in the plugin drawer and I can see it inside the Hollywood gui..
This time I installed Hollywood inside my Home folder of Debian
Here is the output of my terminal that shows which libraries are installed about gtk:

ok, finally i was able to make it work on my system and the solution was really very very simple...
I checked the code of the various examples of rapagui and i simply changed this line:
to this ->
I tested it against both x64-linux and x64-linux-gtk3, and they both work fine
