Loading native libgtksourceview shared library failed

[lamg]

Description

A basic example using GtkSource fails to run with the following output

UnhandledException - unhandled exception: System.DllNotFoundException: Unable to load shared library 'GtkSource' or
one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable

Steps to reproduce

• copy to your local machine the project at https://github.com/lamg/exercises/tree/master/gtk_fsharp/gir_core/source
• execute dotnet publish -c release and then bin/release/net8.0/source

Investigating the issue

• execute export LD_DEBUG='libs bin/release/net8.0/source'
• execute bin/release/net8.0/source 2> result.txt

Inspecting the output at result.txt

• it shows the program is looking for /usr/lib/x86_64-linux-gnu/libGtkSource.so
• it should be looking for libgtksourceview-5.so instead

Actually it should be looking for libgtksourceview-5.so.0 as it is defined in the Gir file from the GNOME sdk.

Can you confirm this file is available?

Which version of Ubuntu are you using?

I assumed wrongly it would be looking for libgtksourceview-5.so, nevertheless /usr/lib/x86_64-linux-gnu/libgtksourceview-5.so.0 exists in my system.

The above mentioned result.txt file in my machine shows this line. To me this suggests there's something wrong with the way the path is determined.

Problem solved, forgot to call GtkSource.Module.Initialize(), like the example shows here. Thanks!
