It means that main() does not exist in the source code file(s) you are compiling.

Two choices:
1. create an object to link later on: add the -c option to CCOPTS
2. edit the file and add a valid main()

cc options
Thanks a lot Jim for your answer.
The file is having only functions and these functions are accessed in other c functions

I cannot have main in this .

Thanks and regards

need to create library?
I think you want to create a library of functions.
Try this and see

cc +Z -I Include_directory -c filename.c

This will give a .o file.

Use ld now

ld -b filename.o -o shr_fil_name.so

This creates a shared library. Use the -l option in cc to include this library while compiling the actual C programs. I hope that helps.
