how to compile node-v4.2.4 with armv7 without fpu?

I have a device whose cpu is armv7 but without fpu. I can compile node with option --with-arm-float-abi=soft, but when I run "node", "Illegal instruction (core dumped)" happened. root@router:/tmp/target/bin# ./node -v v4.2.4 root@router:/tmp/target/bin# ./node --v8-options | head -2 target arm v7 vfp3 soft ARMv7=1 VFP3=1 VFP32DREGS=0 NEON=0 SUDIV=0 UNALIGNED_ACCESSES=1 MOVW_MOVT_IMMEDIATE_LOADS=0 COHERENT_CACHE=0 USE_EABI_HARDFLOAT=0 The tool objdump showed me that there are instructions (such as vpush, vpop...) in use which are not supported by my cpu (arm v7 without fpu). For the further, I found openssl and v8 in the source of node use fpu's instructions. the configure line as below ./configure --prefix=target --dest-cpu=arm --dest-os=linux --without-snapshot --with-arm-float-abi=soft --fully-static Can somebody tell me how to compile node-v4.2.4 without fpu supported? source code: nodejs-v4.2.2 arm version: Cortex-A9 Floating-Point Unit (FPU)(Optional)
