tests/tcg/hello-i386.c is probably a good place to start. It wants to be built with an i386 compiler like so: i386-linux-gcc -nostdlib -Wall -O2 -g -fno-strict-aliasing -static -o hello-i386 hello-i386.c and then run with qemu-i386 ./hello-i386 which should print "Hello World". There's also a hello-arm which you can build with arm-linux-gnueabihf-gcc -Wall -g -O2 -marm -c -o hello-arm.o hello-arm.c arm-linux-gnueabihf-ld -o hello-arm hello-arm.o and run with qemu-arm ./hello-arm to print "Hello World". (You can probably compile and link in one step, but for some reason tests/tcg/Makefile is doing it with two steps.) thanks -- PMM
