The first step before including the µC/DNSc is to have a working project with the µC/TCP-IP. As previously mentioned, Micriµm may offer starting example with µC/OS-III kernels and µC/TCP-IP and even with µC/DNSc for many evalboards.
If no project that include includes µC/TCP-IP is available, you should follow the µC/TCP-IP - Getting Started Guide to start with a working TCP/IP project before starting integrating to integrate µC/DNSc. Then you can follow the following steps to build and run your first µC/DNSc sample application.
...
Once you have a working project with your RTOS and µC/TCP-IP additional modules are needed by the Micriµm DNC client that are not necessarily already included in your project. Therefore, be sure to add µC/CPU, µC/LIB and µC/Common to your project.
Refer to the following manuals for further information about MIcrium Micrium modules:.
Optional module
µC/DNSc comes with a set of command that can be executed from a shell command line tool. If you want to use it you have to include µC/Shell to your project:
Including µC/DNSc Source Code
Include the following files in your project tree from the µC/DNSc source code distribution, as indicated in Figure - µC/DNSc Source Code.

As indicated in the Figure - µC/DNSc Source Code, all the files in the Source folder must be added to your project tree. File under the folder Cmd can be added if µC/Shell is already included in your project.
Compiler settings
Finally, add the following include paths to your project’s C compiler settings:
\Micrium\Software\uC-DNSc
\Micrium\Software\uC-TCPIP
\Micrium\Software\uC-Shell (optional if uC/Shell is used)
...
Copy the files from the uC-DNSc configuration folder into your application as illustrated in Figure - Copying Template Files.

dns-c_cfg.c/.h pair of files, define µC/DNSc module static parameters and run-time configuration structure. Refer to section Module Configuration for more details on all the configurations inside templates files.
...
The µC/DNSc Module uses additional heap memory space. Therefore, it is possible that your sample application will require more allocation of heap memory. If ti is the case, you can increase the HEAP memory size of your sample project, refer to section µC/LIB Memory Management Configuration for more details on the heap usage.
