As with Node 0.12.0 and 0.12.1, there are no-precompiled ARM versions of 0.12.2 on the main site.
I’ve built for Pi 1 (ARM v6) and ODROID-C1/Pi2 (ARM v7). The latter was built on an ODROID-C1 and it seems to run fine on the Pi 2 since both are ARM v7. It took 1 hr 15 mins to compile compared to 4+ hrs on the Pi 1.
“make test” on the ODROID gave the same results as on the Pi 1: [10:33|% 100|+ 784|- 4]: Done
