You can download a pre-built binary from the releases or you can cross compile the app for windows xp; i'll add a nix way soonish

You can download a pre-built binary from the releases or build it yourself using the nix flake.

## Development
12
+
13
+
this project uses nix for cross-compilation to windows xp. the key was using an older nixpkgs (22.05) since newer mingw toolchains use windows apis that don't exist in xp.
14
+
15
+
### Quick Start
16
+
17
+
```bash
18
+
# enter the dev environment (or use direnv)
19
+
nix develop
20
+
21
+
# build the app
22
+
nix build
23
+
24
+
# deploy to my xp vm folder
25
+
deploy-to-xp
26
+
```
27
+
28
+
### Editor Setup (Zed)
29
+
30
+
to get proper intellisense for win32 apis in zed:
31
+
32
+
```bash
33
+
# generate .clangd config with proper mingw headers
34
+
setup-dev
35
+
36
+
# restart zed
37
+
```
38
+
39
+
this creates a `.clangd` file that points to the actual mingw-w64 headers and avoids gcc intrinsics that cause clang issues.
40
+
41
+
### Build Details
42
+
43
+
- uses mingw-w64 cross-compiler targeting i686-w64-mingw32
44
+
- statically links runtime to avoid dll dependencies
45
+
- targets windows xp (winver=0x0501) for maximum compatibility
46
+
- older nixpkgs (22.05) prevents "procedure entry point" errors on xp
