"... exists in the ARTX Library. Do you have this product?" Even if you do have the product, the Linker is telling you that you haven't included it in your project. If you have the product, you will also have the documentation that tells you how to use it!
"Do you have this product?"" yes I am having the ARTX.h ARTX_Config.c and ARTX_Config.h files... .I have an updated version of uvision3 too....

Do I need to change anything in ARTX_config file? t.senthil
"Do I need to change anything in ARTX_config file?" What does the Manual say?
"yes I am having the ARTX.h ARTX_Config.c and ARTX_Config.h files" The error messages tell you that the functions you are missing are: fopen, fprintf, and fclose. Do you have definitions for those functions anywhere in your source code? Probably not. Probably, they are in a Library that forms part of the ARTX Product. if so, you need to include this Library in your project (or select suitable project options that will cause it to be included). Once again, the Manual will tell you how to do this. http://www.keil.com/ararm/
