Building a dll with Go 1.7

Is there a way to build a dll against Go v1.7 under Windows ?

I tried a classic

go build -buildmode=shared main.go

but get

-buildmode=shared not supported on windows/amd64

update Ok, I've got my answer. For those who are interested :!topic/golang-dev/ckFZAZbnjzU

As of Go 1.10, -buildmode=c-shared is now supported on Windows.

Release notes:

So now compiling to DLL is a one-liner:

go build -o helloworld.dll -buildmode=c-shared

I believe the headers are only compatible with GCC. If you're only exposing C-types, this should not be a big issue. I was able to get LoadLibrary to work in Visual Studio without the header.

Release notes: So now compiling  DLL that can be called from any Windows executable or another DLL. These others (executables and DLLs) can be written in C, but don't have to be - they can be written in Go. We (Go executables we build) use system DLLs (produced by Microsoft) all the time.

go build -buildmode=c-archive

====> will build ExportHello.a, ExportHello.h

Take the functions built in ExportHello.a and re-export in Hello2.c

gcc -shared -pthread -o Hello2.dll Hello2.c ExportHello.a -lWinMM -lntdll -lWS2_32

====> will generate Hello2.dll

Any new suggestions? I no longer have 1.8.6. I even went through the registry. I reinstalled 1.7.6 cleared out the typescript folder and reinstalled 1.7.6 which did add the pertinent files back into the directory but after doing a clean on the solution I get the COMPUTE_PATHS_ONLY.ts not found. I tried to rebuild and get the same thing.

There is a project on github which shows how to create a DLL, based on, and thanks to user7155193's answer.

Basically you use GCC to build the DLL from golang generated .a and .h files.

First you make a simple Go file that exports a function (or more).

package main

import "C"
import "fmt"

//export PrintBye
func PrintBye() {
    fmt.Println("From DLL: Bye!")

func main() {
    // Need a main function to make CGO compile package as C shared library

Compile it with:

go build -buildmode=c-archive exportgo.go

Then you make a C program (goDLL.c) which will link in the .h and .a files generated above

#include <stdio.h>
#include "exportgo.h"

// force gcc to link in go runtime (may be a better solution than this)
void dummy() {

int main() {


Compile/link the DLL with GCC:

gcc -shared -pthread -o goDLL.dll goDLL.c exportgo.a -lWinMM -lntdll -lWS2_32

The goDLL.dll then can be loaded into another C program, a freepascal/lazarus program, or your program of choice.

The complete code with a lazarus/fpc project that loads the DLL is here:

Building Applications and Components with Visual Basic .NET, Now it's time to go into more detail. Every managed Figure 1.7 provides a more realistic view of the actual assemblies used by a typical Visual Basic . The above trick will create a libssh2.dll that is statically linked with libvcruntime.lib instead of vcruntime.lib which means you do not need to have VCRUNTIME140.DLL or VCRUNTIME140D.DLL on your system.

  • -buildmode=shared is a Go shared library, which wouldn't make a DLL anyways. You most likely were looking for buildmode=c-shared, though that hasn't been worked on for windows yet, and you can follow issue #11058
  • Btw, Go 1.10 does support building windows DLLs since update in Oct 10, 2017. go build -buildmode=c-shared That single command will generate any DLL for Windows systems. refer to:
