--- icon: material/file-code --- # Build from source ## :material-graph: Requirements ### sing-box 1.11 * Go 1.23.1 - ~ ### sing-box 1.10 * Go 1.20.0 - ~ ### sing-box 1.9 * Go 1.18.5 - 1.22.x * Go 1.20.0 - 1.22.x with tag `with_quic`, or `with_utls` enabled ## :material-fast-forward: Simple Build ```bash make ``` Or build and install binary to `$GOBIN`: ```bash make install ``` ## :material-cog: Custom Build ```bash TAGS="tag_a tag_b" make ``` or ```bash go build -tags "tag_a tag_b" ./cmd/sing-box ``` ## :material-folder-settings: Build Tags | Build Tag | Enabled by default | Description | |------------------------------------|----------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `with_quic` | :material-check: | Build with QUIC support, see [QUIC and HTTP3 DNS transports](/configuration/dns/server/), [Naive inbound](/configuration/inbound/naive/), [Hysteria Inbound](/configuration/inbound/hysteria/), [Hysteria Outbound](/configuration/outbound/hysteria/) and [V2Ray Transport#QUIC](/configuration/shared/v2ray-transport#quic). | | `with_grpc` | :material-close:️ | Build with standard gRPC support, see [V2Ray Transport#gRPC](/configuration/shared/v2ray-transport#grpc). | | `with_dhcp` | :material-check: | Build with DHCP support, see [DHCP DNS transport](/configuration/dns/server/). | | `with_wireguard` | :material-check: | Build with WireGuard support, see [WireGuard outbound](/configuration/outbound/wireguard/). | | `with_utls` | :material-check: | Build with [uTLS](https://github.com/refraction-networking/utls) support for TLS outbound, see [TLS](/configuration/shared/tls#utls). | | `with_acme` | :material-check: | Build with ACME TLS certificate issuer support, see [TLS](/configuration/shared/tls/). | | `with_clash_api` | :material-check: | Build with Clash API support, see [Experimental](/configuration/experimental#clash-api-fields). | | `with_v2ray_api` | :material-close:️ | Build with V2Ray API support, see [Experimental](/configuration/experimental#v2ray-api-fields). | | `with_gvisor` | :material-check: | Build with gVisor support, see [Tun inbound](/configuration/inbound/tun#stack) and [WireGuard outbound](/configuration/outbound/wireguard#system_interface). | | `with_embedded_tor` (CGO required) | :material-close:️ | Build with embedded Tor support, see [Tor outbound](/configuration/outbound/tor/). | | `with_tailscale` | :material-check: | Build with Tailscale support, see [Tailscale endpoint](/configuration/endpoint/tailscale). | | `with_ccm` | :material-check: | Build with Claude Code Multiplexer service support. | | `with_ocm` | :material-check: | Build with OpenAI Codex Multiplexer service support. | | `with_naive_outbound` | :material-check: | Build with NaiveProxy outbound support, see [NaiveProxy outbound](/configuration/outbound/naive/). | | `with_cloudflared` | :material-check: | Build with Cloudflare Tunnel inbound support, see [Cloudflared inbound](/configuration/inbound/cloudflared/). | | `badlinkname` | :material-check: | Enable `go:linkname` access to internal standard library functions. Required because the Go standard library does not expose many low-level APIs needed by this project, and reimplementing them externally is impractical. Used for kTLS (kernel TLS offload) and raw TLS record manipulation. | | `tfogo_checklinkname0` | :material-check: | Companion to `badlinkname`. Go 1.23+ enforces `go:linkname` restrictions via the linker; this tag signals the build uses `-checklinkname=0` to bypass that enforcement. | It is not recommended to change the default build tag list unless you really know what you are adding. ## :material-wrench: Linker Flags The following `-ldflags` are used in official builds: | Flag | Description | |-------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `-X 'internal/godebug.defaultGODEBUG=multipathtcp=0'` | Go 1.24 enabled Multipath TCP for listeners by default (`multipathtcp=2`). This may cause errors on low-level sockets, and sing-box has its own MPTCP control (`tcp_multi_path` option). This flag disables the Go default. | | `-checklinkname=0` | Go 1.23+ linker rejects unauthorized `go:linkname` usage. This flag disables the check, required together with the `badlinkname` build tag. | ## :material-package-variant: For Downstream Packagers The default build tag lists and linker flags are available as files in the repository for downstream packagers to reference directly: | File | Description | |------|-------------| | `release/DEFAULT_BUILD_TAGS` | Default for Linux (common architectures), Darwin, and Android. | | `release/DEFAULT_BUILD_TAGS_WINDOWS` | Default for Windows (includes `with_purego`). | | `release/DEFAULT_BUILD_TAGS_OTHERS` | Default for other platforms (no `with_naive_outbound`). | | `release/LDFLAGS` | Required linker flags (see above). | ## :material-layers: with_naive_outbound NaiveProxy outbound requires special build configurations depending on your target platform. ### Supported Platforms | Platform | Architectures | Mode | Requirements | |-----------------|--------------------------------------------------------|--------|-----------------------------------------------------------------| | Linux | amd64, arm64 | purego | None (library included in official releases) | | Linux | 386, amd64, arm, arm64, mipsle, mips64le, riscv64, loong64 | CGO | Chromium toolchain, glibc >= 2.31 (loong64: >= 2.36) at runtime | | Linux (musl) | 386, amd64, arm, arm64, mipsle, riscv64, loong64 | CGO | Chromium toolchain | | Windows | amd64, arm64 | purego | None (library included in official releases) | | Apple platforms | * | CGO | Xcode | | Android | * | CGO | Android NDK | ### Windows Use `with_purego` tag. For official releases, `libcronet.dll` is included in the archive. For self-built binaries, download from [cronet-go releases](https://github.com/sagernet/cronet-go/releases) and place in the same directory as `sing-box.exe` or in a directory listed in `PATH`. ### Linux (purego, amd64/arm64 only) Use `with_purego` tag. For official releases, `libcronet.so` is included in the archive. For self-built binaries, download from [cronet-go releases](https://github.com/sagernet/cronet-go/releases) and place in the same directory as sing-box binary or in system library path. ### Linux (CGO) See [cronet-go](https://github.com/sagernet/cronet-go#linux-build-instructions). - **glibc build**: Requires glibc >= 2.31 at runtime - **musl build**: Use `with_musl` tag, statically linked, no runtime requirements ### Apple platforms / Android See [cronet-go](https://github.com/sagernet/cronet-go).
