error: expected ',' or '...' before 'buffer'

[vtpgit]

I tried including the two file in Arduino and this is what I get when I add

In one of the cores the function core_share_init() must be called.

#include "cores_communication.h"
void setup() {
core_share_init();
}
void loop() {}

*In file included from C:\Users\Administrator\Documents\Arduino\GIGA_MemoryShare_Cores_Dev\GIGA_MemoryShare_Cores_Dev.ino:24:0: C:\Users\Administrator\Documents\Arduino\GIGA_MemoryShare_Cores_Dev\cores_communication.h:53:41: error: expected ',' or '...' before 'buffer' int put_to_m4(const int const restrict buffer, const unsigned int size);** ^~ Any ideas what I am doing wrong?

Thank you!

I believe it expects a pointer. Use int put_to_m4(const int *const restrict buffer, const unsigned int size); Don't forget the *. For some reason, yours doesn't have it.

I verified and the git repo has it.

If it doesn't work, remove all that bloat of const and restrict: int put_to_m4(int * buffer, unsigned int size); And don't forget to also fix the .c file.

Mine does have the * pointer, not sure why github deleted it when I copied/pasted. Screenshot attached:

I would like to check something else first, this could ne an environment error.

OK cleaning the pointers helped, I left only bare pointers.

However when compiling the whole thing barfed like that

etc... etc...

I'm not sure at that point if it's worth continuing, I might as well rewrite everything from scratch myself.

If you have any ideal please help.

Thank you!

OK cleaning the pointers helped,

I didn't realize before. Arduino uses g++ to compile and, in C++ there is no restrict keyword up to now (there is talk about adding it in a future revision of the standard).

error: '_Atomic' does not name a type typedef _Atomic _Bool atomic_bool; ^~~

The errors about the _Atomic keyword are because of the inclusion of the <stdatomic.h> header (a C library) I believe. C++ has the <atomic> library and that one should be used. Make this substitution and see if it fixes the problem. Perhaps, you can replace the _Atomic _Bool or atomic_bool for something like std::atomic<bool> (after including the lib <atomic> of course). In this link, there is a workaround https://stackoverflow.com/a/45343624/4885430
