full install step share about xiangshan

Thanks.

We recommend using stable verison verilator, like v4.204. Verilator v4.210 has performance issues on XiangShan.

[fatalfeel]

the -Xmx64G for the most people, will build failed. better using -Xmx16G,
I try to use -Xmx24G ok too

[poemonsense]

We need a larger stack for the normal XiangShan, which 16G tends to be not enough. So we prefer to keep it large and sorry for the inconvenience.

[fatalfeel]

not enough for compile or simulation?
i use 16G compile and simulation successful

make emu CONFIG=MinimalConfig produces minimal XS

[fatalfeel]

i will keep this open for first building user, if sir Poemonsense need to close u can do it by urself

This repo contains scripts for setting up XiangShan develop environment, and a detailed document (in Simplified Chinese) about how to build and sim XiangShan. First building users may give it a try :)

请问一下你是怎么在Ubuntu装上g++-riscv64-linux-gnu的？

[fatalfeel]

you do need build gcc in OpenXiangShan project, but if you need try this

#preinstall
apt install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev libusb-1.0-0-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev device-tree-compiler pkg-config libexpat-dev libfl-dev

#export must add to last line of ~/.bashrc
export RISCV="/opt/riscv"
export ROCKETCHIP="/root/riscv_cpu/rocket-chip"
export MAKEFLAGS="$MAKEFLAGS -j8"

git clone --recursive https://github.com/freechipsproject/rocket-tools

cd ~/riscv_cpu/rocket-tools
git submodule update --init --recursive
./build.sh
