我正在安装 Rocket-Chip 存储库。我按照以下说明进行操作https://github.com/chipsalliance/rocket-chip. 指示如下：
$ git clone https://github.com/ucb-bar/rocket-chip.git
$ cd rocket-chip
$ git submodule update --init
$ export RISCV=/path/to/riscv/toolchain/installation
$ git clone https://github.com/freechipsproject/rocket-tools
$ cd rocket-tools
$ git submodule update --init --recursive
$ export RISCV=/path/to/install/riscv/toolchain
$ export MAKEFLAGS="$MAKEFLAGS -jN" # Assuming you have N cores on your host
system
$ ./build.sh
当我启动最后一个命令时，出现以下错误和警告：
Makefile:5347: warning: rewriting of the instruction set for "check-
recursive"
Makefile:4181: warning: ignoring of the instruction old set for "check-
recursive"
ar: `u' modifier ignored since `D' is the default (see `U')

我已经检查了 makefile 所涉及的所有文件和文件夹的权限，但根本不起作用。有人能帮帮我吗？
