go 工具鏈目前[不支持編譯 windows 下的動態鏈接庫][1],不過[支持靜態鏈接庫][2]。
想要產生dll,可以這樣 workaround ,參考 golang [issuse#11058][1]:
- 首先得裝一個 windows 下的 gcc 開發環境,我用了 [msys2][3] 。
- 需要配置一個快點的源,我用[中國科技大學的源][4]。
- 安裝 gcc 工具鏈:
pacman -S mingw-w64-x86_64-toolchain
(注意這里有個坑, msys64 根目錄有兩個mingw64.*
文件會導致 pacman 安裝失敗,我是暴力重命名了沖突的文件。)
- 編譯靜態鏈接庫:
go build -buildmode=c-archive -o libfoo.a foo.go
- 准備導出符號定義文件, Sum 就是需要導出的函數名:
$ cat foo.def EXPORTS Sum
- 用 gcc 把靜態鏈接庫轉成動態鏈接庫:
gcc -m64 -shared -o foo.dll foo.def libfoo.a -Wl,--allow-multiple-definition -static -lstdc++ -lwinmm -lntdll -lWs2_32

Go從1.5開始就支持編譯編譯C調用的動態鏈接庫
Shared libraries
Go 1.5 can produce Go shared libraries that can be consumed by Go programs.
Build the standard library as shared libraries:
$ go install -buildmode=shared std Build a "Hello, world" program that links against the shared libraries: $ go build -linkshared hello.go $ ls -l hello -rwxr-xr-x 1 adg adg 13926 May 26 02:13 hello Go 1.5 can also build Go programs as C archive files (for static linking) or shared libraries (for dynamic linking) that can be consumed by C programs.
更多詳細的用法可以參考
golang.org/s/execmodes
試試看 buildmode=c-archive 編譯到 .a .h 包給 c 語言使用。。但是不支持 x86 只支持 amd64
$ go install -buildmode=shared std
-buildmode=shared not supported on windows/386
不支持 Windows...
