## Build Configuration Filtering

Use the Build Configuration Filtering preference panel in the Preferences window to select which platforms are visible when creating new projects or build configurations.

### SBSv2 tab

Use the SBSv2 tab to select configurations for that build system. SBSv2 is the prefered build system for the most current SDKs.

Figure 1. Platform Filtering Preferences page (SBSv2 tab)

##### Table 1 Platform Filtering Preferences — SBSv2 items

Item | Explanation
--- | ---
Default Configurations | Select platform build targets to be displayed for OS 9.5 and later when creating new projects and build configurations. BSF’s are gone in SBSv2. All build configurations (platform/target), including the built-in platforms (WISNCW, ARMV5), are declared in xml files in the \sbs\lib\config directory.
Product Variant Configurations | Lists all the known variants created for the selected build configuration.
Rescan Default Configurations | Click to rescan for sbs and build configurations in the installed SDKs.
Add Variant | Adds a variant build to the selected build configuration. SDK must support variant builds for this to work.
Remove Variant | Removes the selected variant from the list of available variants.
Refresh | Select this button to obtain a fresh list of configurations from SBSv2. The list is refreshed each time Carbide starts up, but this button will allow users to add configuration xml files and get those new configurations without restarting Carbide.c++.
