I think Kubo is compiled with go1.19.10 and this error is related to using a newer version of go to compile the plugin.

@emendir do you still get this error when using the latest go (0.20.x) and kubo (0.21.0) ?

[emendir]

Thanks for your suggestion.
I'm assuming you meant go 1.20.x instead of go 0.20.x
The result of testing go 1.20.5 together with kubo 0.21.0 was the following:

The make build step failed with the following error:

./set-target.sh v0.14.0
go build  -trimpath -buildmode=plugin -o "example-plugin.so" "main/main.go"
# github.com/lucas-clemente/quic-go/internal/qtls
~/go/pkg/mod/github.com/lucas-clemente/[email protected]/internal/qtls/go119.go:6:13: cannot use "The version of quic-go you're using can't be built on Go 1.19 yet. For more details, please see https://github.com/lucas-clemente/quic-go/wiki/quic-go-and-Go-versions." (untyped string constant "The version of quic-go you're using can't be built on Go 1.19 yet. F...) as int value in variable declaration
make: *** [Makefile:31: example-plugin.so] Error 1

As far as I understand it seems to be complaining that a dependency of kubo 0.21.0 doesn't yet work with go 1.19, from which I infer it won't doesn't with go 0.20.5 either.

Just to clarify, the latest dist.ipfs.io releases of Kubo are built with go 1.19.10, so plugins need to be built with that.

You can build Kubo with a newer version of Go yourself, and then use that for the plugin too (I don't know if you did).

@emendir did you try building kubo and the plugin with the same version of Go (as is required for Go plugins) as was suggested above? Note: the version of Go that kubo is built with on dist.ipfs.io is described in the build file https://dist.ipfs.tech/kubo/v0.21.0/build-info and kubo has ipfs version --all which will tell you the Go version as well.

iiuc Hector provided useful README update in #30 about using the matching version of Go

Support for Go >1.20 is out of scope here (we will add support when Go 1.21 is out, ETA Kubo 0.23).
