Unable to compile simple go program using foundationdb

Question

Trying to cross compile on macos arm for linux. My sample project looks like this:
main.go:

package main

import(
 "github.com/apple/foundationdb/bindings/go/src/fdb"
)


func main() {
        fdb.APIVersion(630)
        fdb.MustOpenDatabase("fdb.cluster")
}

go.mod

module fdbtest

go 1.19

require github.com/apple/foundationdb/bindings/go v0.0.0-20221026173525-97cc643cef69

require golang.org/x/xerrors v0.0.0-20191204190536-9bdfabe68543 // indirect

go.sum

I've installed foundationdb go lang bindings via go get github.com/apple/foundationdb/bindings/[email protected]

but when I do env GOOS=linux GOARCH=amd64 go build I get the following errors:

 env GOOS=linux GOARCH=amd64 go build                                                                                       
# github.com/apple/foundationdb/bindings/go/src/fdb

<...>
../../../go/pkg/mod/github.com/apple/foundationdb/bindings/[email protected]/src/fdb/generated.go:94:9: too many errors

So it seems that it cannot find any of the types from fdb. Yet the KeyConvertible and the NetworkOptions (and others) exist in ../../../go/pkg/mod/github.com/apple/foundationdb/bindings/[email protected]/src/fdb/fdb.go

My golang version: go version go1.19.3 darwin/arm64
Newer fdb go bindings (7.1.25, 7.1.0) seem to behave the same...

what am I missing here?

Answer 1

arm64 architecture installations may be problematic but you should also check some requirements.

In my case with amd64 architecture the default Ubuntu installation for Windows 11 WSL2 was missing some dependencies:

• mono
• libc6
• cmake

After installing the above packages the errors were gone.

If you follow https://github.com/apple/foundationdb/tree/main/bindings/go you can see how to install the package properly.
