Hello Michael,
thank you for your quick reply. As you can see from the answer of my
other mail, you exactly hit the spot with mentioning adding
'--disable-gtk3' to 'autogen.input'.
Thank you really much for supporting me!
Kind regards,
Christian

I have the problem that vscode-cpptools "dim inactive regions" option
dims the region in the statement
`#if GTK_CHECK_VERSION(4,0,0)`
and additionally Intellisense also does not work in that region.
When changing the statement to
`#if GTK_CHECK_VERSION(3,0,0)`
the respective region is not dimmed anymore and also IntelliSense
works again.
However when running the application, the following code
`cout << gtk_get_major_version() << "." << gtk_get_minor_version() <<
"." << gtk_get_micro_version() << endl;`
returns `4.5.0`
Therefore, I know for a fact that at compile time level my
application uses GTK 4.5.0.
What specific source file are you editing?
Are you building both the gtk3 and gtk4 VCL plugins? (gtk3 is enabled
by default. You can check e.g. whether you have a file
'instdir/program/libvclplug_gtk3lo.so' after the build, in addition to
'instdir/program/libvclplug_gtk4lo.so')
Most of the files in 'vcl/unx/gtk3' are used for both, the gtk3 and
the gtk4 VCL plugin. (s. how the .cxx files in 'vcl/unx/gtk4/' include
the ones from the 'vcl/unx/gtk3 directory';
'vcl/Library_vclplug_gtk3.mk' and 'vcl/Library_vclplug_gtk4.mk' are
the corresponding Makefiles where you can see the compiler flags used).
So where does the vscode-cpptools know the GTK version from and
therefore is able to judge `GTK_CHECK_VERSION(4,0,0)`?
I don't have much experience with VS Code myself, but I'd suppose it
uses the macro from the corresponding Gtk 3 header (e.g.
'/usr/include/gtk-3.0/gtk/gtkversion.h' on my Debian testing system).
I also looked into my project's `.vscode` folder into the
`c_cpp_properties.json` file and added the GTK4 library install dir
`"/usr/local/include/gtk-4.0"` as follows:
```
{
"configurations": [
{
"name": "Linux",
"includePath": [
"${default}",
"/usr/local/include/gtk-4.0",
"/usr/include/gtk-3.0",
"/usr/include/glib-2.0",
"/usr/lib/x86_64-linux-gnu/glib-2.0/include",
"/usr/include/pango-1.0"
],
"defines": [],
"cStandard": "c17",
"intelliSenseMode": "linux-clang-x64"
}
],
"version": 4
}
What happens if you drop the Gtk 3 include path "/usr/include/gtk-3.0"
in addition?
Alternatively, if you don't need the gtk3 VCL plugin, you could also
try adding '--disable-gtk3' to your 'autogen.input'.
