Most like you have already googled the answer or given up. Well, hoping for the first option, I have not seen into this in detail but I found two workarounds. 

Seems to me that the Robot IR Remote library has an issue there. 

You can either remove the files IRremoteTools.cpp and IRremoteTools.h from your directory C:/programs/arduino/libraries/Robot_IR_Remote/src/ (or the approriate path for your OS) or go to 

<a href="https://github.com/z3t0/Arduino-IRremote" rel="nofollow">https://github.com/z3t0/Arduino-IRremote</a>

and get yourself an IR remote library that is working as it is. 

Seems to me the numeric values to a given IR signal vary between both libraries. But then again I did not go into any details there. Perhaps someone else can elaborate on that point.

Good luck.

I've just bought an arduino beginner pack (sunfounder) and I had the same issue.
What I did is:

<ul>
<li>Delete the library IrRemote: (C:\Program Files\Arduino\libraries\RobotIRremote)</li>
<li>Download a good one. Can be found at <a href="https://codeload.github.com/z3t0/Arduino-IRremote/zip/master" rel="nofollow">https://codeload.github.com/z3t0/Arduino-IRremote/zip/master</a></li>
<li>Install it using the Arduino program's menú: Program -> Include Library -> Add .ZIP library</li>
</ul>

just delete RobotIRremote file in the libraries and download the IRremote-master againly copy paste into the libraries file

blocks|key|2227011|text|在Mac上，我使用了终端应用程序，并执行了一个"cd+/Applications/Arduino.app“，然后是一个"open+.”。这打开了Arduino应用程序中的Finder。然后，我导航到contents/Java/libraries并删除了RobotIRRemote文件夹。然后我转到main+Arduino/Sketch/Include+Library.../Manage+Libraries并搜索了IRRemote库。在我导入该库后，没有任何问题！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2227012|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

On the Mac I used the Terminal application and did a "cd /Applications/Arduino.app" followed by an "open .". That opened up the Finder inside the Arduino application. I then navigated to the contents/Java/libraries and removed the RobotIRRemote folder. I then went to main Arduino/Sketch/Include Library.../Manage Libraries and did a search for the IRRemote library. After I imported that the libraries complied without any problem!

i am a beginner in arduino and that's my first IR project and yet i have a problem with compiling ...

Arduino error : TKD2 was not declared in this scope

About the code i used is the example IRrecvDemo .
