Bevy is data-driven engine written in Rust. The repository of Bevy contains several examples which can be started by a command like:
git clone --depth 1 https://github.com/bevyengine/bevy.git cd bevy cargo run --example alien_cake_addict
Users of openSUSe might experience following error:
hread 'main' panicked at 'Unable to find a GPU! Make sure you have installed required drivers! For extra information, see: https://github.com/bevyengine/bevy/blob/latest/docs/linux_dependencies.md', crates/bevy_render/src/renderer/mod.rs:121:10 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
The problem is caused by missing Vulkan libraries in the system. This can be confirmed by running vkcube which may result in the following error:
vkEnumerateInstanceExtensionProperties failed to find the VK_KHR_surface extension. Do you have a compatible Vulkan installable client driver (ICD) installed? Please look at the Getting Started guide for additional information.
Check which graphic card is installed in the system:
sudo lspci -nnk | grep -A3 VGA
Which might result in a message like this:
00:02.0 VGA compatible controller [0300]: Intel Corporation CometLake-U GT2
With this knowledge, it’s clear that library Vulkan Intel is missing and can be installed simply by:
sudo zupper install libvulkan_intel
Application vkcube should work after this change.
