What error is there in my C header file?
I'm currently programming in C for a university project. Specifically, it involves various tours that are to be implemented with their own structures and nodes. For this, I've predefined the structures in the file tours.h. This is the file: #ifndef TOUR_H
#define TOUR_H
typedef struct island{
char island_name[20];
char opening_hours[20];
}Iceland;
typedef struct Node{
Iceland island;
struct Node *next;
struct Node *prev;
}Node;
typedef struct tour{
int tournumber;
Node *start;
}Tour;
#endif
I have the following problem: the file tours.h is included in the file tours.c with the command #include "tours.h" in order to use the definitions in the header file. The compiler gives me the following error:
1 user-submitted files matching "^[a-zA-Z0-9_]*\.[cC]$" found for compilation: tours.c
Compiler output:
In file included from node.c:9: node.h:11:10: fatal error: island.h: No such file or directory #include "island.h" ^~~~~~~~~~ compilation terminated.I don't understand where the error lies, since I never included an island.h file, but rather included them alongside stdio, stdlib, and string.h. There's also no file named node.h or node.c. Where is the error?

Oh, shit formatting.
Are the files in the same directory?
Yes, they are. We need to upload the files and they will be automatically checked by a compiler. Maybe there’s the mistake?
Well possible if everything works locally, then you should check the upload process again, will nen archive be uploaded? Are there any requirements for the directory structure or the like?
In addition to the error message, is the actual call of the compiler reproduced? This would be interesting for other flags, as there are also different language standards.
All right, thanks. Then I’ll ask that in the next time
This looks almost as if there were a predetermined node.h, node.c etc. – or as if there were several files thrown together.
Have added an image above again from the attempt with empty island.h. The message is gone, another error appears
Well, the error message is that the HEader node.h, which is included by node.c, includes the unexisting island.h.
If you had this nei so that the nciht can be like nen Cruft, please look again into the task of whether it is explicitly required that typedefs should always be in HEader with the same name or the like.
If there were other ways to get on track would be an empty island.h with upload and see what happens.
No, I didn’t have a node.h. I never defined and never included.Hab yes defined the nodes in the.h tours. The task does not specify how to name files and headers
Have uploaded the exact error as picture. The error is always displayed, even if the C-File does not contain any Includes at all
Sagmal, node.h is also mentioned in the error message.
Did you have a node.h?
Or does the task require that these files should contain the corresponding typedefs?
And you say there are keien island.h udn You don’t include them? Then it must happen indirectly…
Upload a stripped C-file that doesn’t include anything in your HEader, using only the Sys-Includes.
If the error is then reproducible, it becomes interesting.
I just packed the type definitions from the header file directly into the tours.c and he still gives the same error
I’ve never had any problems with this: the principle is so, you can upload all the files individually and then everything should go. The compiler then checks and gives red or green light
I made a tour.c and included your tour.h. I can compile it without mistake.
(Compiler: gcc)
Can I send you the whole code? would be very cool if you could look over it
I compiled it now. It works without any problems, and the program also works.

Thanks to you, you can explain to yourself where the mistake with the compiler comes from
