Installing Cross-compilers

sudo apt-get update
sudo apt-get install gcc-arm-linux-gnueabihf
sudo apt-get install binutils-arm-linux-gnueabi

Write a simple test program

printf '#include<stdio.h>\n\nint main(){\n\tprintf(\"Hello,World!\\n\");\n\treturn 0;\n}' > test.c

Compile test.c to test.o

arm-linux-gnueabihf-gcc test.c -o test.o

Query the information (it should indicate 32-bit ARM executable)
```
file test.o 
```

Find the ip of odroid to connect via eth0 (replace eth0 with whichever connection you have)

export eth0_ip=$(ifconfig eth0 2>/dev/null | awk '/inet addr:/ {print $2}' | sed 's/addr://')
nmap ${eth0_ip}/24

Copy the binary to the odroid (replace the ip with whichever ip you found)
```
scp test.o odroid@10.42.0.220:~/
```
In the odroid,
```
~/test.o
```
The output should be “Hello,world!\n”.
