Both symbols are only used in si.c.  Single file symbols
should be static.  So move the si_default_state and
si_default_size to si.c and change their
storage-class-specifier to static.

Remove unneeded si_blit_shaders.[c|h]

Uff, well NAK.

IIRC this was intentionally moved into a separate file because it is rather large and not related to anything in si.c.

It's unlikely that we are ever going to update it, but I would still rather want to keep it separated.

You should rather just include si_blit_shaders.h in si_blit_shaders.c.

Do you mean #include "si_blit_shaders.c" in si.c or similar ?

No, as far as I can see you are getting this warning because of a missing previous prototype for the exported array.

This can be avoided if you add si_blit_shaders.h as an include to si_blit_shaders.c.

Regards,
Christian.


This could have the same effect of while keeping these separate failes

Tom

Christian.
