What do you think? We currently have kept nodejs 0.10.x for backward compatibility with armv5 or non-VFP CPUs, in parallel with 0.12.x for armv6+ with VFP CPUs. > > I was able to sucessfully build for an arm926t (armv5) with a VFPv2 FPU. > > > > So: > > - is the failure a runtime failure or a build time one? > > From memory it only show up at runtime as an illegal instruction.

OK, so let's do as upstream wants it: - armv6 or above ir required - VFPv2 or above is required Thanks! :-) BTW, you can see my WIP patch there (moving target, the branch may get rebased from time to time; handle with care! ;-) ): http://git.buildroot.org/~ymorin/git/buildroot/log/?h=yem/node Regards, Yann E.
