是否可以使用依赖项编译golang代码？ [关闭]

Question

Is it possible to compile golang code with dependencies? For an executable file was small.

Answer 1

As mentioned in "Linking golang statically" (Vincent Batts):

As long as the source being compiled is native go, the go compiler will statically link the executable.
Though when you need to use cgo, then the compiler has to use its external linker.

A pure go program will show like this:

$> go build ./code-pure.go
$> ldd ./code-pure
        not a dynamic executable
$> file ./code-pure
./code-pure: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), statically linked, not stripped

This isn't so with cgo, unless you add an extra flag like:

go build --ldflags '-extldflags "-static"' ./code-cgo.go
# or, with gccgo
go build -compiler gccgo --gccgoflags "-static" ./code-cgo.go

Reminder, even with Go 1.5 (which uses go for compilation, and not gc), gccgo will still be there.
