`libgtkglext1-dev` is deprecated and has been removed from recent Debian releases. GtkGLExt hasn't been maintained since around 2012 and doesn't support GTK+ 3 or later.
First, check if it's still available in your repositories: ```bash apt-cache search libgtkglext ``` If you actually need `libgtkglext1-dev`, it's likely gone from Debian Trixie. Your options are: **Option 1: Try Debian Bullseye (oldstable)** ```bash # Add bullseye sources temporarily echo "deb http://deb.debian.org/debian bullseye main" | sudo tee /etc/apt/sources.list.d/bullseye.list sudo apt update sudo apt install libgtkglext1-dev sudo rm /etc/apt/sources.list.d/bullseye.list sudo apt update ``` **Option 2: Build from source** ```bash sudo apt install libgtk2.0-dev libglu1-mesa-dev libgl1-mesa-dev pangox-compat git clone https://gitlab.gnome.org/Archive/gtkglext.git cd gtkglext ./autogen.sh make sudo make install ``` Note: I'm currently unable to access https://gitlab.gnome.org, which might be an issue on my end. You may need to find a mirror. I have no idea what you are doing, but if possible, consider migrating to modern alternatives like GtkGLArea (part of GTK+ 3), Epoxy, SDL2, or GLFW. --- https://zolk3ri.name -------- Original Message -------- On 2025-10-04 16:01, Martin Nicholas via Factor-talk <[email protected]> wrote: > Installing dependencies I get: > E: Unable to locate package libgtkglext1-dev > > Also tried the latest build - no joy. > > -- > Regards, > > Martin Nicholas. > > E-mail: [email protected] (Address will be valid throughout 2025). > > > _______________________________________________ > Factor-talk mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/factor-talk > _______________________________________________ Factor-talk mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/factor-talk
