Hello, wondering if I can get a bit of help.
Just updated arduino 1.0.6 and teensyduino 1.2 on a teensy 3.1 and now fastled does not compile, same version (2.1) that I was using before on the old version. Same thing happened when I did a fresh download of everything in a new directory. Reverting back to the old version now…
Make sure you have the most recent version of fastled2.1 (and that you don’t have stale copies of the library around)
Also - see where it says “This report would have more information with
“Show verbose output during compilation”
enabled in File > Preferences.” In what you posted? Please do that in the future - gives more information that may be helpful the next time 
Thanks… though I just downloaded the zip of 2.1 branch from git just now, so I’m pretty sure it’s the latest version…
Just seeing if this was a known error or if it’s something wrong on my end. I’ll see if I can figure it out.
I’m assuming you mean 1.20, btw, for the teensyduino version (1.18 was a recent version).
I suggested checking the versions again because I’m using this exact setup at home (the 3.1 is my preferred platform) - and the error you are getting describes a thing that Paul changed with 1.20 that I had to merge a fix in for a while ago.
Yeah - you’re not using the most recent version of 2.1 - the line numbers in your error messages don’t line up with the code that’s in the repo.
