what is wrong??
why ide gives me this error: expected primary-expression before '.'token
please help me =)
You should post the whole error, which also says the "e" is a problem.
This line:
if (IRrecv.decode(e results))
should probably say:
if (irrecv.decode(&results))
The "e " should be an "&" and "IR" should be "ir"... it compiles ok for me with those changes.
HTH...
now the erroe is: expected unqualified-id before'if'...
now the erroe is: expected unqualified-id before'if'...
Well it compiles for me with the two changes I made....
Is that the whole error?- if not post the whole error.
Have a look at the line that gets highlighted, and there's also a line number in the error. Maybe you made a typo when you made the fixes, so post the code again.

That's the error I already told you about... thought you had fixed it already?
yes, and this is the results...

This also compiles fine for me so maybe you have an old version of the IRremote library (Download the latest version from here) or it's not installed correctly.
I had compiled it in 101 with no errors and I get similar (but not identical) errors to you when I compile in 104 without the IR library, so Riva's probably right, it's a library thing.
Edit.... when I copy the library from my 101 folder to 104, it compiles clean in 104, so yep, def seems a library related problem.
thanks!!
