Hi Dexter, apparently your .S file was not compiled. I suspect your Makefile does not have rules for this case.
Also note that the preprocessor will be run on .S files, but the output needs to be valid assembler code. Including a file that uses the C syntax to define prototypes is an error. Using the preprocessor is mostly useful for #ifdef, especially when combined with -D on the command-line.
Edit: The other functions you mention are in libfxgc.a so GCC will take them from the archive silently and not complain.

Thank for the answer and for the help!
I understood the first part and the last one but I have some difficulties with the central part
Premise: for the configuration i simply extracted the sdk and overwrite the libfxcg on the folder ( changing the name on MKG3AFLAGS in the makefile), nothing else.
I begin to think I did something wrong at this level.
I assume that the assembler code (0x1187 ?) is valid becase i think the error would have been different (or maybe no error at all).
If that can be helpful i attach the folder project:

Thanks again for the help, there is very little information and help on these libraries

Alright, so the middle part is less complicated than it looks, especially since I read something wrong. ^^'"
Actually by "assembler code" I mean the syntax of the file. If you #include a C header then your .S file will contain C code, and the assembler will be confused.
I thought it was the case, but I have misread your image (I thought you had included system.h in Restart.S). Sorry for the confusion.
-
I think a key point here is that you added Restart.S to the libfxcg source directory instead of your project's file. This is fine, but then you need to recompile libfxcg.a or your new file will never be used. There is a Makefile in the libfxcg folder: you definitely need to run that before you try to link your project.
Be careful though - this will overwrite libfxcg.a. Since you mentioned that you have overwritten it manually, please make sure you lose no work in the process.
If you need information on the library, please look up Cemetech's WikiPrizm: http://prizm.cemetech.net/index.php/Main_Page
In particular the "All Pages" page is a useful index: http://prizm.cemetech.net/index.php/Special:AllPages
(If you can, please consider attaching your files to your post using the "Fichier joint" input in the form. This will make the thread easier to follow if the files ever goes away from Google Drive.

I simply move the entire libfxcg folder on the project folder, all works now! Thank you so much! I feel like an idiot

That'd be a bit extreme, but why not. Try and keep the two separated if possible to keep the code structure clean.
Feel free to ask if you run into another problem. Also, whatever you develop with that cg50 is certainly welcome here.
