Problems trying to cross-compile for ARM on Linux

[zoelilylain]

Everything goes right until:
arm-linux-gnueabi-g++ -g -O2 -o sbasic ../../lib/lodepng/lodepng.o main.o input.o device.o image.o decomp.o -L../../../src/common -lsb_common -lm -ldl -lpthread -lpcre -ldl ../../lib/lodepng/lodepng.o: file not recognized: file format not recognized collect2: error: ld returned 1 exit status

Am I correct in assuming I'm going to need to cross-compile the dependencies as well? the file in question reports as a x86_64 elf when I run "file" on it.
