| _Make sure you followed the install instructions to [prepare the system](install_instructions.html#system-preparation) and install the [compiler toolchain](install_instructions.html#compiler-toolchain)._ |

| ## Building software |
| |
| ```console |
| $ cd $REPO_TOP/sw/examples/hello_world |
| $ make CC=/tools/riscv/bin/riscv32-unknown-elf-gcc |
| ``` |
| |
| The build process produces a variety of output files. |
| |
| * `.elf`: the linked program in ELF format |
| * `.bin`: the linked program as plain binary |
| * `.dis`: the disassembled program |
| * `.vmem`: a Verilog memory file which can be read by `$readmemh()` in Verilog code |
