Hello  guo

To generate the library file, please open Project Properties, and select the linker output type as 'Library', and rename the artifact extension as 'lib'. You also need to remove the link command file from the building.

Thank you for your help very much. if I put my library function in another path, which is not my application program's path, how can I call the library function in my application program? can you give me an example? if you can give me an example with mc56f84789 in codewarrior 10.4, it's the best.

Hello guo

In your application project, please add your library in the Linker Input of the Project Properties, and in the C file which calls the library function, add the external function declaration for it.   Hope it helps!
