Hello ,Stefan. Thanks for your reply! Now I am trying to compile the Genode toolchain myself. I used the scripts in tools/tool_chain but still encountered the same problem. I think I should add some flags in tools/tool_chain, but I have no idea what to add and where to add the flags. I have tried add

"GCC_MAKE_OPT += -mfloat-abi=hard -mfpu=vfp" but it make failed. So could you give me some hint on this? Thanks a lot.
