why does error C141 and C213 come while compiling gpiflongxfr example??
You have the code in front of you, and the manual gives you a description of each error code. If studying these doesn't help you, then post a brief extract of the code in which the error occurs, and the full text of the message(s) - then perhaps we can help. BTW: don't forget to use the [pre] and [/pre] tags when posting code (but replace '[' and ']' with '<' and '>')
