Arm-linux-gnueabihf-gcc compiler error?


I want to cross-compile the SDL library to A20 project,but when i compile the example in the test directory with “arm-linux-gnueabihf-gcc” compiler,it make a mistake.what should i do ?

./configure --prefix=/home/reilly/sambashare/sdl/sdllib-emd --target=arm-linux --host=arm-linux CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ LD=arm-linux-gnueabihf-ld AS=arm-linux-gnueabihf-as AR=arm-linux-gnueabihf-ar

i already add the “–prefix=/home/reilly/sambashare/sdl/sdllib-emd” parameter,but…that’s why?
