This is a GTK theme/icon issue with GNAT Studio

Hi @montgrimpulo! This error occurs when GNAT Studio can't find required icons in your system's GTK theme.

Quick fixes to try:

1. Install missing GTK theme packages:

# Ubuntu/Debian:
sudo apt install adwaita-icon-theme gtk3-engines gtk3-engines-breeze

# Fedora/RHEL:
sudo dnf install adwaita-icon-theme gtk3-engines

# Arch Linux:
sudo pacman -S adwaita-icon-theme gtk-engines

2. Reset GTK theme to default:

# Set GTK theme environment variable
export GTK_THEME=Adwaita
./gnatstudio

3. Install complete GNOME icon set:

# Ubuntu/Debian:
sudo apt install gnome-icon-theme gnome-icon-theme-extras

# This provides fallback icons

4. Alternative launch method:

# Force GTK to use system theme
GTK_THEME=Adwaita:dark ./gnatstudio
# or
GTK_THEME=Adwaita:light ./gnatstudio

If the above doesn't work:

Check your system:

• What Linux distribution are you using?
• Did you install GNAT Studio from package manager or manually?
• Are you running a custom desktop theme?

Temporary workaround:

# Create missing icon directory
mkdir -p ~/.icons/Adwaita
# Then reinstall icon theme

Let me know your Linux distro and I can provide more specific instructions!

Hi,

I use Kubuntu 25.04 and GNAT Studio 20250417. All needed themes were installed, but the app could not find the icon. I don't know why, possibly due to a lack of permissions, though my account had all the required ones. To fix, I did the following:

1. Copied /usr/share/icons/gnome/ to ~/.icons/.
2. Executed gtk-update-icon-cache -f ~/.icons/gnome/.
