i have copied the multiple file program out of the book. when i come to compile/build the program i get an error saying undefined reference to "clear_line()" (a function with in the program). the function is defined in the line.h file written in the line.c file and i have included the line.h in both main file and line.c file. as per the book.
if i try and build either line.c or word.c seperatly by right clicking on them i get a pop up message box saying "that file isnt assigned to any target"
what am i doing wrong
many thanks
