What did you do?

I tried to compile the program shown at the bottom of this issue using go build.

What did you expect to see?

I expected my program to compile or at least give me an error in my code.

What did you see instead?

Attaching source code for program. I simply have no clue what this error is telling me and there doesn't seem to be any answers on the web as to how to get a clue.

Program: main.go

package main

import "C"
import (
	"log"
	"golang.org/x/sys/windows"
)

var hModule windows.Handle

func init() {
	err := windows.GetModuleHandleEx(0x01, nil, &hModule)
	if err != nil {
		panic(err)
	}

}

func main() {
	log.Println("Hello")
}

Here is the go.mod file

module github.com/steowens/goWebview

go 1.19

require golang.org/x/sys v0.3.0

Apparently commenting out the following line fixes the compilation issues;

import "C"

And I found this: https://stackoverflow.com/questions/30412951/unresolved-external-symbol-imp-fprintf-and-imp-iob-func-sdl2

So apparently something in the go package "golang.org/x/sys/windows" is incompatible with "C"

That stack overflow answer suggests a remedy. Did you try it?

steowens · 2022-12-25T21:28:17Z

I did try it but it created other problems. Things get flaky using golang.org/x/sys/windows in conjunction with "C". The stack overflow basically further down says that it's a matter of having libraries compiled with older compilers mixing with code compiled with up to date compilers. https://msdn.microsoft.com/en-us/library/bb531344.aspx#BK_CRT So basically stay away from packages which contain static linked code compiled by an older compiler. I just figured you might want this brought to the attention of the dev team to see if there is anything that needs to be looked at.

robpike · 2022-12-25T22:59:54Z

Maybe @alexbrainman has ideas. I don't know much about the Windows build.

steowens · 2022-12-25T23:52:37Z

This has happened to me on different projects so much as to render go almost unusable for Windows development at least. This project which does not even include "C" gets the same issue, here is the Golang dependency tree for the project. The problem is this is not a toy project and it kind of stinks having to verify each and every new dependency to see if it will render the project uncompilable with this issue. It's friction. It slows development and kind of erodes the value proposition that go enables you to get stuff done faster. I had to comment out every single thing in my application until I was able to chase it down to github.com/mattn/go-sqlite3. Once that dependency was gone I could compile again.

go env output?
how did you install the go toolchain?
how did you install the gcc toolchain?
does it build if the whole thing is built from scratch (go build -a)?

steowens · 2022-12-26T19:12:45Z

Here is a complete command line repo starting from building a new project and creating a minimal main.go file which reproduces the issue.

As far as how I set things up I followed the directions from go on how to set up go, and I followed the directions from MINGW on how to set that up. I don't want to repeat that process. But if you wish to introspect the current state I would be happy to work with you on that. But in general people should not have to rebuild their entire environment every time they encounter such issues, there needs to be a more frictionless way to troubleshoot setups.
Otherwise, all I need to do as a for profit vendor of tool chains, is to throw sand in the works by publishing flawed setup directions on your open source tool chain, and leverage my corporate power to cause those links to bubble up to the top of the search results on Google, to create enough frustration among new users to steer them away from your project. Sure some will be stubborn enough to work through the frustration but critical mass is king when it comes to adoption. Critical mass has a gravitational coefficient that draws people into it's field. Who wants to work really hard to build something that nobody ends up using because friction prevented it from gaining critical mass? Where is the fun in that?
I know plenty of people with PhD's in topics no commercial company is interested in and they struggle to pay their bills doing jobs they hate because nobody is willing to pay them to do the things they love. Open source is the same way, being an expert in a stack nobody is using is like that. So adoption is important and friction kills adoption.

We're not asking for your environment to be built from scratch, just the inputs for this particular program, using the invocation given above (go build -a), where:

	-a
		force rebuilding of packages that are already up-to-date.

steowens · 2022-12-26T20:16:15Z

Ah I misunderstood I built an entirely new project and thought that would be good enough. Turns out that doing what you asked
go build -a actually fixes the issue. I had to create another project anyhow to repro the error since I fixed my original project by removing references to the x/sys/windows stuff.

compileFail no longer fails to compile. I can tell you that this switch you have there really needs to bubble up to the top of search results when people encounter issues like this. Hopefully this trouble report will help that happen. Some people are good at following directions without knowing the WHY in the direction but others not so much for those of us in the latter category we really respond better to instructions when we understand the motivations behind them. I think it probably has something to do with the difference between neurotypical and neruoatypical people.

                                                                                                                                                                                                                                                                                              Mode                 LastWriteTime         Length Name

In that case, it is related to #51007 and should get resolved in the next release as part of #47257

Closing as there's nothing else to do.

What version of Go are you using (go version)?

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?
