#### Building with the PowerShell script
|
||||
|
||||
As an alternative to building through Visual Studio, run the PowerShell helper from the repository root:
|
||||
|
||||
```powershell
|
||||
.\scripts\win_build.ps1
|
||||
```
|
||||
|
||||
The script locates a supported Visual Studio installation, finds Qt from `Qt6_ROOT` or a standard `C:\Qt` installation, configures a Release Ninja Multi-Config build, and then builds it. Pass `-Cores <count>` to set the parallel build count; by default it uses all logical processors:
|
||||
|
||||
```powershell
|
||||
.\scripts\win_build.ps1 -Cores 8
|
||||
```
|
||||
|
||||
The resulting application is placed in `<rpcs3_root>\build\bin`.
