Official EthernetClient Sample Not Compiling - Ambiguous overload error with latest Arduino 1.0.6

[OzmoOzmo]

The code sample below - the official Arduino sample code.
will not compile:

    http://arduino.cc/en/Reference/ServerAvailable

My public code libraries use the EthernetClient library like this - and same method I used is mentioned in several books and several ethernet sources - but it will not compile anymore on 1.0.6

(I have tried official 1.0.6 and the nightly build ARDUINO 1.6.0rc3 - 2015.02.03)

The problem is EthernetClient cannot be tested for true/false anymore (it used to have a overloading that allowed you to query it being ready by using boolean comparitor).

The sample code has not worked since 1.0.5

Official Sample Code:

EthernetClient client = server.available();
if (client == true) { //compiler error here
}

What is the correct new way to do this test now - and will the documentation be changed or the IDE/Compiler be changed back (best option)?

Thanks very much.

Hi, the code is wrong. We'll fix it asap. Correct syntax is if (client) {

[OzmoOzmo]

I think might be better fix in library code if possible than update documentation...

Several printed media is currently showing the way it worked in 1.0.5

eg. page 163 of this book.

https://books.google.co.uk/books?id=yvclBgAAQBAJ&pg=PA163&lpg=PA163&dq=arduino+"if+%28client+%3D%3D+true%29"

And this book (Non-English language)
https://books.google.co.uk/books?id=LwLzAwAAQBAJ&pg=PA185&dq=arduino+"if+%28client+%3D%3D+true%29"

And there are a lot of apps and code samples using the old way - this search shows it will break a lot out there unnecessarily.

You're right. I've proposed a change in #2618. Please leave your comment

Please try one of the IDEs at #2618 (comment)

@OzmoOzmo corrected in the reference. Can i close this issue?

Thanks very much - that does indeed sort that problem.

Sorry not getting back to you sooner - but I was trying to get the whole
project compiling to fully test it

• still having trouble converting depreciated memory functions like
  const prog_uchar allmonths[] = {"JANFEB..."} etc.

But thanks for getting EtherClient working anyway :)
