Hi, I'm having a quick look into it. I'm just downloading the latest IDE to confirm, however it looks like it is due to C++11 not being active in 1.6.5

I recall it was activated in 1.6.5r2 (current is 1.6.5r5).

Sorry I should have checked and added a note for the minimum version. I'll also fix the code so the C++11 only features are #defined to not cause error in the older IDE's (streaming is C++11 specific and parts of the code are not prevented from compiling).

Chris--A commented 9 years ago

A small update, 1.6.5r5 does not include the changes pushed to the repo. I have opened an issue for this and will report back once worked out. (https://github.com/arduino/Arduino/issues/3791)

For now, I'm going through the code and I'll make it C++98 safe. I release the changes in version 1.1.6 today.

Thank you for taking the time to report this.

PS: if you would like to use the library now, you can enable C++11 by adding the changes found here to your platform.txt file: https://github.com/arduino/Arduino/commit/ddf4d878fdb39173b872f69149fb4cf1cd9fd017

Chris--A commented 9 years ago

This is now fixed. Version 1.1.6 is available and should appear in the library manager within the hour.

As a result, in IDE versions below 1.6.6 (not released yet), Streaming and variadic printing are unavailable. You can however enable C++11 yourself to access these features.

Thank you for your input.
