When you import a custom server that was exported in the INSTALLED or AUTOEXEC state, it is restored in the same state on the target system. A custom server executable in the import file is installed without being rebuilt; if it doesn’t install, it is rebuilt and installed. You must have the C or C++ compiler installed on the target system to rebuild the executable. The system-generated main() file (if any), the custom server header file and the custom server Makefile are regenerated.
