The build system exists in the CVS module build. Once the build module has been checked out, the environment variable BUILD_ROOT needs to be set to the path of the directory. Build system commands are in the build/bin subdirectory of the build module, and therefore it needs to be added to you PATH environment variable on UNIX and Windows. Macintosh usage is more complex.
| Environment Variable | Description |
|---|---|
| BUILD_ROOT | Set to the path of the build module. |
| PATH | Make sure to include build/bin. |
| SYSTEM_ID | Set this to the system id of the target platform if the default isn't what you want. |
Additional support programs may be required.
