NODEJS_CPU = arm # V8 needs to know what floating point ABI the target is using. There's also # a 'hard' option which we're not exposing here at the moment, because # buildroot itself doesn't really support it at present. ifeq ($(BR2_SOFT_FLOAT),y) NODEJS_ARM_FP = soft else NODEJS_ARM_FP = softfp endif ....' It seems there is no support for 'hard' floating point for now. To solve that, I intend to force '-DUSE_EABI_HARDFLOAT' in nodejs compilation package, but I don't know the way to do that; any advice ? Another way to solve the problem could be to use 'soft' or 'softfp' floating point strategy but menuconfig does not propose this tuning, maybe...
