also hitting this issue, only reproducible on linux, works fine on darwin, both arm64 and amd64

/usr/bin/ld: /go/pkg/mod/github.com/valyala/[email protected]/libzstd_linux_amd64.a(cover.o): warning: relocation against `stderr@@GLIBC_2.2.5' in read-only section `.text'

/usr/bin/ld: final link failed: bad value

easy to reproduce with just

package main

// #cgo CFLAGS: -fPIC
import "C"
import "github.com/valyala/gozstd"

//export Compress
func Compress(msg *C.char) *C.char {
	input := []byte(C.GoString(msg))
	output := gozstd.Compress(nil, input)
	return C.CString(string(output))
}

func main() {}

then

go build -o zstd.so -buildmode=c-shared .

note: the cgo directive doesn't work, I just added as the error message suggested, but it makes no difference

alright, issue found, the c archive for linux amd64 wasn't built with -fPIC as the gcc error says
as a workaround you can clone this repo, rebuild the .a file for your platform, and go mod edit -replace the dependency on your project with the cloned one

example

git clone https://github.com/valyala/gozstd.git ../gozstd
cd ../gozstd
git checkout v1.17.0 # or whatever release you want # could be parsed from go.mod
MOREFLAGS=-fPIC make clean libzstd.a
cd - # wherever your package is
go mod edit -replace github.com/valyala/gozstd=../gozstd

now the build works like a charm 🙂

now... is this a bug when the .a files where generated and committed to this repo? or is there some intention behind the lack of the -fPIC flag? I'd lie if I'd say that I fully understand how all this works, so I'm not sure what's the best way to address this issue

@valyala sorry for the tag, but it would be really nice to get your input
I guess that a pr from me updating the .a file won't be accepted, right?
I guess there wouldn't be any way of verifying that it hasn't been tampered with, or it doesn't introduce some issue for other users

I got this error when I want to execute this command

There is a problem with my GCC. I will fix it after reinstalling OS
