I went to release Go 1.24.3 and Go 1.23.9 into our build system and some packages began failing when trying to cross-compile to darwin/amd64:
I've reproduced it down to a small example:
mkdir repro
cd repro
go mod init example.com/failure
cat > main.go << EOF
package main
import (
_ "github.com/ebitengine/purego"
)
func main() {
}
EOF
go mod tidy
GOOS=darwin GOARCH=amd64 go build -o main main.go
What did you see happen?
I received an error:
link: duplicated definition of symbol dlopen, from github.com/ebitengine/purego and github.com/ebitengine/purego
What did you expect to see?
I expected it to continue to compile, as it did in Go 1.24.2
