The 86Box Jenkins provides all kinds of pre-release testing builds for advanced users. These are linked to the 86Box git repository on GitHub; a new build is produced with the latest source code every time the repository is updated.
Testing builds are development snapshots which may contain bugs, incomplete features or other issues. These should only be used if you know what you’re doing.
Standard builds (86Box) are compiled with default options. Release versions of 86Box are based on standard builds.
Debug builds (86Box-Debug) are standard builds compiled with debug symbols and no optimizations, to allow for debugging with
gdb and other tools if you don’t have a full 86Box development setup. Debug builds run slower than standard builds due to the removal of optimizations and addition of debugging features.
Development builds (86Box-Dev) are compiled with
DEV_BUILD=y, enabling additional features which are currently under development. These new features might not work, either partially or entirely, and the development team reserves the right to change or remove them at any time.
Optimized builds (86Box-Optimized) are standard builds which have been optimized for use with a specific CPU family on the host machine. Optimized builds provide slight performance improvements, especially on older or low-end hosts; however, the aggressive optimizations employed may result in bugs not present on standard builds.
There are many different optimized binaries available for each build, with each one corresponding to a CPU family. The table below lists most CPUs currently supported by optimized builds, along with the respective binaries you should use with them, as well as their codenames (as shown on an identification tool such as CPU-Z).
Using the wrong optimized binary for your CPU will result in poor performance and/or crashes.
