guayadeque: assert "m_size != wxSize(0, 0)" failed in GetImageCount(): Invalid image list

[Martin Gansser]

Hi,

since i started guayadeque to compile with wxsqlite3-4.8.2-5.fc36.x86_64 and
wxGTK-3.1.5-6.fc36.x86_64 compile, the program starts on F37/F38 with the following error
message:

How can I solve this ?

Do you see the same problem with wxWidgets 3.2 on F38?

You didn't answer whether you see the same problem on F38.  Have you tried 
it there?

Never mind - I tried it there and do observe the same problem.

The issue appears to be that guayadeque is creating a wxImageList with its 
default constructor (wxImageList()), here:
https://github.com/anonbeat/guayadeque/blob/master/src/ui/radios/RadioPan...

This creates a wxImageList where the images are of width=0, height=0 which 
is basically useless (hence the assert).

Instead, it should specify a width and height for the wxImageList using 
this constructor:
https://docs.wxwidgets.org/trunk/classwx_image_list.html#a7c99503e0d851e8...

Either that, or build without Debug enabled and you won't see the asserts.

Thank you for the detailed explanation.
In the meantime, I'll compile guayadeque without debug flag until the developer solves
this.
