While trying to install QEMU as instructed at http://riscv.org/getting-started.html#qemu, the **"qemu-system-riscv: command not found"**error shows up when the following command is run: qemu-system-riscv -hda [Location of root.bin] -kernel [Location of vmlinux] -nographic
I checked the riscv-softmmu direcory and qemu-system-riscv is there in the directory.
