Description

在使用go 1.23.0编译sing-box时，我遇到了一个问题

github.com/sagernet/sing-box/cmd/sing-box

link: github.com/sagernet/tfo-go: invalid reference to internal/poll.execIO
make: *** [makefile:20: build] Error 1

无论是否使用添加标签，我了解到，该问题似乎指向 tfo-go

通过对分叉源的查阅

Windows support with Go 1.23 and later

tfo-go's Windows support requires extensive usage of //go:linkname to access Go runtime internals, as there's currently no public API for Windows async IO in the standard library. Unfortunately, the Go team has decided to lock down future uses of linkname, starting with Go 1.23. And our bid to get the linknames we need exempted was partially rejected. Therefore, we had to make the following changes:

• Windows support is gated behind the build tag tfogo_checklinkname0 when building with Go 1.23 and later.
• With Go 1.21 and 1.22, tfo-go still provides full Windows support, with or without the build tag.
• With Go 1.23 and later, when the build tag is not specified, tfo-go only supports listen with TFO on Windows. To get full TFO support on Windows, the build tag tfogo_checklinkname0 must be specified along with linker flag -checklinkname=0 to disable the linkname check.

我发现了该问题的解决方法，你需要添加 -ldflags="-checklinkname=0" 标签
举例：go build -ldflags="-checklinkname=0" ./cmd/sing-box
