I don't see errors, I see warnings. Can you post the complete error message? To fix the "no return" message, just edit the file shown and add the return statement. Some compilers complain; others don't.

Thanks for comment and remedy.

You have right - is not an a error. i have change the subject.
i have in MySQL_Encrypt_sha1.cpp two lines insert:

1. at line 89 in size_t Encrypt_SHA1::write(uint8_t data)
2. at line 95 in size_t Encrypt_SHA1::write(uint8_t* data, int length)
   new lines: return(0);

have you idea for rectification [-Wunused-parameter] in MySQL_Packet.cpp?
thanks

I compiled the code and do not see those errors. Those parameters are being used. So, let's try this. What board are you using and which programmer do you have selected? BTW, most warnings like this can be safely ignored.

You can also just turn the warnings off in the preferences. Just saying...
