can not use g++
Thank you so much for your open source project, it's very interesting. I am new to FPGA. I'm very sorry if the question is simple. But I have some problems compiling a C++ "hello world" program on a debian system. It reported the following error " -bash: g++: command not find" .It makes me confused，can you help me please！Thanks a lot.
debian@debian:~/cppfile$ g++ a.cpp -o a
-bash: g++: command not found
I use g tab tab and really don't have g++. I use Genesys2, the parameter is rocket64b2gem. There may be some problems with my ethernet, not sure if this is the cause. Also, I replaced /etc/apt/sources.list.

I use Genesys2
Good choice.
the parameter is rocket64b2gem
I don't recommend 'gem' variants - unless you are a Gemmini developer. Gemmini hardware is slow and not 100% stable yet, rocket64b2 works much better.
There may be some problems with my ethernet
Yes, there is a problem. Your Ethernet is not working - according to 'ip a' output.
not sure if this is the cause
Yes, it is the cause - you need working Ethernet and Internet access to install g++.
Also, I replaced /etc/apt/sources.list.
Why? sources.list contains address of Debian repo, you need it to install g++.
With working Ethernet, after apt update && apt upgrade, apt install g++ will work as expected:
root@debian:~# apt install g++

Thank you so much for your help! I have rebuilt the project, using rocket64b2 and not changing the source. It was indeed the ethernet issue. I didn't plug in the network cable at first. Now I plugged in the network cable and connected it to the computer, but I found that the genesys2 could not ping the external network . My computer can ping genesys2 and log into debian using ssh. My computer can ping the external network. I also know very little about networking.I need to learn some networking knowledge. My eth0 only shows ipv6, I manually configured ipv4.

You need to connect the board to a router. The router will assign IPv4 address, do packet forwarding, address translation etc. You could setup your computer to act like a router, but it is complicated. Just connect the board directly to your router.
Thank you very much! I have connected to the Internet now, and set the computer to router mode through what you said. I also successfully updated g++ and now it can run cpp programs.
debian@debian:~/cppfiles$ ls
a.cpp
debian@debian:~/cppfiles$ g++ a.cpp -o a
debian@debian:~/cppfiles$ ls
a a.cpp
debian@debian:~/cppfiles$ ./a
i=0hello world!
i=1hello world!
i=2hello world!
i=3hello world!
i=4hello world!
I did it through windows network sharing. I also tried the bridge but it didn't work. I still replaced the sources.list when updating g++ because I'm in China.
deb [arch=riscv64] http://mirrors.aliyun.com/debian-ports unstable main
deb [arch=riscv64] http://mirrors.aliyun.com/debian-ports unreleased main
I also modified the file /etc/network/interfaces to make genesys2 and the computer on the same network segment.
auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
