+
+The error message indicates a conflict between the `MOTOR` definition in the 
+**RELEASE.local** file and the `SUPPORT` support directory because of the 
+mounting configuration or symbolic links between different machines.
+
+To resolve this error, you can modify the `CHECK_RELEASE` setting to either `NO` 
+or `WARN` in the **configure/CONFIG_SITE** file. This will disable or allow the build 
+to continue despite the inconsistency detected. However, please note that it's 
+important to ensure the paths in the **RELEASE*** files accurately reflect the correct 
+locations of the support applications to avoid potential issues during runtime.
+
+Just like the **RELEASE.local** file, the **CONFIG_SITE.local** file allows for local 
+customization of the build configuration. The lines 
+`-include $(TOP)/../CONFIG_SITE.local` and `-include $(TOP)/configure/CONFIG_SITE.local`
+ in the **configure/CONFIG_SITE** file instruct the build system to include the 
+ **CONFIG_SITE.local** files if they exist in the specified locations. The `$(TOP)` 
+ variable represents the top-level directory of the IOC.
+
+
+ Note: the linux command `$ echo "CHECK_RELEASE = NO" > configure/CONFIG_SITE.local`
