- まず単純に、
$SNIPER_ROOT/riscv/build-riscv.shを実行するとどうなるか。
Setting SNIPER_ROOT to . Header 'bzlib.h' not found in the GCC include paths. Please install 'libbz2-dev / bzip2-devel'. Header 'boost' not found in the GCC include paths. Please install 'Boost'. Header 'sqlite3.h' not found in the GCC include paths. Please install 'libsqlite3-dev / sqlite-devel'. Resolve dependencies and come back!
いろいろ怒られた。これを解決するためには、Dockerなどで必要なコンテナファイルを作っておけばよい。
cd docker make # Ubuntu 22.04 版のDockerイメージがビルドされる
ビルドが完了すると、user-modeでDockerイメージにログインして作業を再開だ。
$ make run docker run --rm -it -v "/home/kimura:/home/kimura" --user 6016:7100 -w "/home/kimura/work/riscv/sniper/snipersim/docker" ubuntu:22.04-sniper-kimura groups: cannot find name for group ID 7100 I have no name!@ccf5be4cd091:/home/kimura/work/riscv/sniper/snipersim/docker$
./riscv/build-riscv.sh Setting SNIPER_ROOT to /home/kimura/work/riscv/sniper/snipersim Please set the PIN_ROOT environment variable to your copy of Pin
次は PIN_ROOTが無いと怒られる。実際にはPINはいらないと思うのだが、とりあえず設定する必要はあるらしい。
IntelのページからPinをダウンロードする： ../snipersim にダウンロードした。
curl -L https://software.intel.com/sites/landingpage/pintool/downloads/pin-3.18-98332-gaebd7b1e6-gcc-linux.tar.gz | tar xvz
export PIN_ROOT=$(realpath ../pin-3.18-98332-gaebd7b1e6-gcc-linux/) I have no name!@b5ce1506619c:/home/kimura/work/riscv/sniper/snipersim$ printenv PIN_ROOT
再び riscv/build-riscv.sh を実行すると、今度はCPU2006のディレクトリが無いと怒られる：これは普通ない気がするので、ダミーのディレクトリを作って対応してみる。
./riscv/build-riscv.sh Setting SNIPER_ROOT to /home/kimura/work/riscv/sniper/snipersim Please set the CPU2006_ROOT environment variable to your installed copy of SPEC CPU2006 v1.2
mkdir ../cpu2006_dummy export CPU2006_ROOT=$(realpath ../cpu2006_dummy/)
再度 riscv/build-riscv.sh を実行すると、今度はツールセットのダウンロードが始まった。こいつはでかそうだ。

最終的に、コンパイルエラーが出た。
1. 修正部分: riscv_decoder の実装の変更
riscv_decoder の実装の部分だ。

riscv_decoder.h
class RISCVDecodedInst : public DecodedInst { public: RISCVDecodedInst(Decoder* d, const uint8_t * code, size_t size, uint64_t address); riscv::inst_t * get_rv8_inst(); riscv::decode * get_rv8_dec(); void set_rv8_dec(riscv::decode d); /// Get the instruction numerical Id virtual unsigned int inst_num_id() const override; /// Get an string with the disassembled instruction virtual void disassembly_to_str(char *, int) const override;
decoder.h では違う関数の形を求めており、これは合っていない。
class DecodedInst { public: virtual ~DecodedInst(); // dtor -- virtual to be able to destroy polymorphically const bool & get_already_decoded() const; void set_already_decoded(const bool & b); size_t & get_size(); const uint8_t * & get_code(); uint64_t & get_address(); /// Get the instruction numerical Id virtual unsigned int inst_num_id() const = 0; /// Get an string with the disassembled instruction virtual std::string disassembly_to_str() const = 0;
以下のような形で修正した。

riscv-tools を確認すると、 riscv-gnu-toolchain は相当古いものを使っているようだ。 riscv-qemu などのリポジトリが存在しなくなっている。
commit a17086ff0ba63df488a511d20ca42c7953f6eecb (HEAD)
Author: Tim Newsome <tim@sifive.com>
Date: Mon Apr 16 12:34:02 2018 -0700
Actually bump to 2.29 now.
とりあえず、現状の最新版にアップデートしてみるとどうだろう：
$ cd riscv-tools/riscv-gnu-toolchain/ $ git checkout 2025.09.28 $ cd .. $ ./build-sift.sh
これで、 riscv-gnu-toolchain のビルドが可能だ。
最後に、全体をビルドし直して完了となる。riscv-toolsが再ビルドされないように気を付ける。

これで完了だ。最初のSniperのビルド環境が整った。
しかし、現状のSniperのRISC-V実装ではいろいろと不備があるので、改善していく。
