### 4.4 Resolve build error #1
This build error occurs for the same reason the build error occurred in step 2.4 (TODO: Add link): `EPICS_BASE` isn't defined.
This build error occurs for the same reason the build error occurred in [step 2.4](2-IOC-deployment.md#24-build-the-ioc-attempt-1): `EPICS_BASE` isn't defined.
The error was much more helpful in step 2.4 because [xxx's CONFIG file prints the user friendly error message](https://github.com/epics-modules/xxx/blob/3c9ec766c3a7107248ef3d2a2f717968ce12ad5d/configure/CONFIG#L16-L23). The motorVMC developer should add a similar check to the motorVMC module.
