I can’t upload the blink sketch. The IDE send an error message : Arduino can just open its own file or .ino and .pde sketch. so the .cpp temp file is not upload (though XOD says that it has been upload sucessfully).
Thank you a lot for trying to help. But I can’t open your attachment, it looks like an empty PNG to me. Could you dump the log to https://pastebin.com/ or https://gist.github.com/ please?
Looking at the log it looks like either #include <inttypes.h> isn’t included in the sketch and so size_t type isn’t available, or some “bad symbols” has appeared in the generated source file.
