display_library: sdl, options="fullscreen" To check which display libraries your Bochs binary supports, run:
Checking for SDL... yes Compile and install
bochs -h | grep display Example output (good):
./configure --enable-sdl --enable-sdl2 --with-sdl Check the output for:
Install dev packages, then reconfigure and recompile.
sudo dnf install SDL-devel
display_library: x
sudo apt install bochs-sdl Then run bochs-sdl instead of bochs , or update your configuration.
display_library: 'sdl' 'sdl2' 'x' 'term' If sdl or sdl2 is missing, you must recompile Bochs or get a different binary. When all else fails, compiling manually ensures SDL support.

display_library: sdl2 If you have a version with multiple libraries, you can also specify options:
This article explains what this error means, why it occurs, and how to resolve it on Linux, Windows, and macOS.
