BUILDING AND RUNNING XV6 BUILDING AND RUNNING XV6
To build xv6 on an x86 ELF machine (like Linux or FreeBSD), run You will need a RISC-V "newlib" tool chain from
"make". On non-x86 or non-ELF machines (like OS X, even on x86), you https://github.com/riscv/riscv-gnu-toolchain, and qemu compiled for
will need to install a cross-compiler gcc suite capable of producing riscv64-softmmu. Once they are installed, and in your shell
x86 ELF binaries (see https://pdos.csail.mit.edu/6.828/). search path, you can run "make qemu".
Then run "make TOOLPREFIX=i386-jos-elf-". Now install the QEMU PC
simulator and run "make qemu".
