How to Static Link with Golang

[realchandan]

Hello there,

Can you provide some guidance on how to static link with Golang?

I've tried three approaches so far but haven't been able to static link the binary.

Approach 1:

I copied the onnxruntime.lib and sherpa-onnx-c-api.lib to the same folder as my main.go file and tried to build using go build, but the resulting binary still required .dll files to run.

Approach 2:

I created a submodule called sherpa_wrapper and did the following:

package sherpa_wrapper

/*
#cgo CFLAGS: -I${SRCDIR}/../sherpa-onnx-v1.11.4-win-x64-static/include
#cgo LDFLAGS: -L${SRCDIR}/../sherpa-onnx-v1.11.4-win-x64-static/lib -lonnxruntime -lsherpa-onnx-c-api -lsherpa-onnx-cxx-api -lsherpa-onnx-cxx-api -lsherpa-onnx-core -lsherpa-onnx-fst -lsherpa-onnx-fstfar -lsherpa-onnx-kaldifst-core -lsherpa-onnx-portaudio_static -lkaldi-decoder-core -lkaldi-native-fbank-core -lespeak-ng -lpiper_phonemize -lssentencepiece_core -lucd -lcargs
#include "c-api.h"
*/
import "C"

// Provide a dummy wrapper func if needed
func InitSherpa() {
	// nothing for now
}

I imported and called InitSherpa in my main program, but this didn't work either.

Approach 3:

I cloned https://github.com/k2-fsa/sherpa-onnx-go locally and modified the go.mod file to point to:

replace github.com/k2-fsa/sherpa-onnx-go => ./local_sherpa-onnx-go

Inside local_sherpa-onnx-go, I pointed its go.mod to:

replace github.com/k2-fsa/sherpa-onnx-go-windows => ./local_sherpa-onnx-go-windows

In the local_sherpa-onnx-go-windows folder, I pasted the .lib files in its root.

But I'm still unable to make it work.

Can you provide some guidance on how to do it?

Please follow our doc to.build.static libs, and copy all generated libs.

There are more than 5 libs

I'm using this instead of building myself.

Where should I place the .lib files after it's built? and is running go build enough?

[csukuangfj]

I imported and called InitSherpa in my main program, but this didn't work either.

Would you mind sharing more error info? Otherwise, it is not possible for us to know what bad things have happened.

I pasted the .lib files in its root.

How did you get sub .lib files?

Also, what exactly are the .lib files?
