Hi i have a problem in linux terminal line. So i tried compiling a file to .o like this

gcc -c palindrome.c

and the error is

palindrome.c:2:21: fatal error: reverse.h: No such file or directory
compilation terminated.

The file reverse.h indeed is in the directory because i copied everything from lab2 directory to lab 3. So why is it saying that? Thanks for the help

From inlab3 either

• add -I../inlab2 to compiler (e.g. gcc -I../inlab2 -c palindrome.c, this will tell gcc to look in ../inlab2 for the header file)




• use #include "../inlab2/reverse.h" in include line (this will give relative path for the header file)




• copy from inlab2 cp ../inlab2/reverse.h . (this will make a copy of the header file available in inlab3)
