Building help

[Keivan-sf]

Hello there, This will be a messy issue description and I'm not experienced in go, so I am sorry in advance

The problem

I can't get the same nekobox_core binary included in nekoray gui client present in /config
os: Ubuntu 22.04.2

What I have done to compile the binary

• I have cloned the repositories that had replace <repo-url> => ../<name> in go.mod (all main branch) respectively and put them on a parent directory and installed the dependencies with go get .
• Also I have uncommented the line replace github.com/sagernet/sing-dns v1.0.0 => ../sing-dns and cloned it as well due to an error where CreateLocalTransport and CreateUDPTransport were undefined.
• I've used go build -tags with_gvisor to build a binary for my system

Why it seems to be a different binary

The reason for that is I have a socks-5 proxy running at a local port and I use vpn-run-root.sh to do the packet flagging and everything for me in order to use it as a vpn (script is not modified I'm simply happy with it) but when I replace nekobox_core path in vpn-run-root.sh with the binary I've compiled, they behave differently, I keep getting this error repeatedly:
dns: exchange failed for connectivity-check.ubuntu.com. IN A: dial tcp 127.0.0.1:8081: no route to internet
Both the script and the sing-box-vpn.json are the same (except the outbound socks port in sing-box-vpn.json which is 8081)
The socks-5 proxy is functioning and the script is fine with the original nekobox_core provided in nekoray client.

I'm wondering if you could provide me with a description of how should this package be compiled, if there is any extra flag or certain commits in parent repositories I have to checkout to or maybe there is a different repo or...
Any help would be appreciated
