[AlexxIT]

PureGo Version

v0.9.1

Operating System

• Windows
• macOS
• Linux
• FreeBSD
• NetBSD
• Android
• iOS

Go Version (go version)

go1.25.4

What steps will reproduce the problem?

1. Build this app for linux/amd64:

package main

import "github.com/ebitengine/purego"

func main() {
	purego.Dlopen("", 0)
}

2. Pack binary with UPX

3. Run result on alpine linux

What is the expected result?

The binary is running

What happens instead?

Binary fail with error:

ld-linux-x86-64.so.2: /tmp/tmp: Not a valid dynamic program

Anything else you feel useful to add?

All works fine in Debian linux. Problem only with purego + upx + alpine. If you remove any of the three components, everything will work.

Alpine likely doesn't work since it uses musl libc which doesn't support dlopen

[AlexxIT]

I don't need purego to work under alpine. My so library also doesn't work under alpine.

But I need my app to work on alpine. Otherwise, I'll have to build two different versions of the app - one with purego and one without.

And everything works if not to pack the app using UPX. But using it is also important.
