$ sudo apt-get install libpixman-1-dev
$ git clone https://github.com/riscv/riscv-qemu.git
$ make build
$ cd build
$ ../configure
($ ./configure --target-list=riscv64-softmmu,riscv32-softmmu)
(option없는 경우 full build 되는 듯)

gdb실행시 아래와 같은 message가 나오는 경우
Reading symbols from /home/suker/RISC-V/sifive/test-u-500/work/riscv-pk/bbl...(no debugging symbols found)...done.
riscv-pk/Makefile.in 에서 gdb flag를 enable해주어야한다.

etc.
아직 eclipse GDB qemu 는 사용할 수 없는듯. arm용 plugin 은 github에 있지만 risc-v 용은 없음.
