Nightly build (fixing issues #2828, #2829, #2830) is not compiling sketches

[aveekbh]

With the nightly build (2015-03-30), sketches fail to compile - even the bare minimum example. The error is:

avr-gcc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found
compilation terminated.
Error compiling.

Platform: Ubuntu 14.10 x86_64 GNU/Linux
avr-gcc (GCC) 4.8.1

The verbise output in http://pastebin.com/6DejC6LM refers to /h/a - this was actually /home/<username>, which I edited out before uploading publicly..

Moving my ~/.arduino15 directory to force Arduino to create it afresh made no difference, sketches still don't compile.

The SHA256 sum of the nightly build download arduino-nightly-linux64.tar.xz is f39363dd2426ac11227ef7df5f22a6301c4bf1b417f6e5695f2e6c458ec1ebc7.

Yes, I fixed that in 1fcd6ff. The download server are pretty overloaded so the newer nightly (I manually started) is taking a bit to come up. Just wait a couple of hours

Hello Federico

This showed up in Ubuntu. Perhaps that label should also be added?

[ffissore]

Right, sorry for having misread. Indeed, the problem is caused by a missing piece of the toolchain. Every toolchain has been updated and the next nightly bundles core 1.6.3, which is identical to 1.6.2 but depends on an updated gcc. Again, just wait a couple of hours. I'm monitoring the CI server: I'll keep you posted when the newest nightly is available

Nightly available, cores upgraded

It works for me.

(But I'm still affected by #2853 so I still can't upload.)

Looks like it's fixed now. I had to rename my ~/.arduino15 directory to get this to work - this forces Arduino IDE to re-generate this. The tools and hardware directory reside here now.

For the record, SHA256 sum of arduino-nightly-linux64.tar.xz is 32cbc18f3092ab6b283c49d44d07577e8ca8a294abd3efcbafa52c33c4bced2d
