This is not the end, it's just a break. This project has become grotesquely mangled and needs a fresh start. So it will have one!
Linuwux Runtime will be back, better than ever. For now, I have the last pushed build on here so you can still access it.
liblinuwux.so — an LD_PRELOAD library that supplies the Linux/Wine-side interpositions required by certain Windows software that expects a specific CPUID-faulting and signal protocol under GE-Proton or CachyOS Proton.
No Proton/Wine source patches, no prefix registry imports, no launcher script rewrites.
Official Valve Proton is not supported. Use GE-Proton or CachyOS Proton.
This project does not configure the host CPU or install any hypervisor. Those are separate system-level steps (UMIP, cpuid_fault support, etc.).
One library (liblinuwux.so) handles both the modern and legacy protocol layouts used by the software it supports. The protocol is detected at runtime — there is no second .so or legacy wrapper.
A process is treated as a target when the Windows executable sits next to a known marker file, for example:
reflex.dll/reflex64.dllwinmm.dllversion.dll
Some older packages include a Windows launcher.exe. On Linux you do not need it. Point Steam / Lutris / Heroic / umu at the actual game binary the same way you do for any other title, and put linuwux only on that game’s launch options.
Prebuilt (needs curl, sha256sum):
curl -fsSL https://raw.githubusercontent.com/brcly/linuwux-runtime/main/install.sh | shInstalls ~/.local/lib/liblinuwux.so and ~/.local/bin/linuwux.
From source (needs git, gcc):
./build.sh --installSame destinations; plain ./build.sh afterward refreshes the installed .so.
Per game launch options — not the whole Steam/Lutris UI (~/.local/bin on PATH):
linuwux %command%
If a GUI app (e.g. Steam) was already running when you fixed PATH, restart it once — or use ~/.local/bin/linuwux %command% until you do.
