I'm not sure what I'm doing wrong or if I understood at all the plugin
package of 1.8
I have a plugin like the example exampleplugin/main.go (build with "go
build -buildmode=plugin")
package main
// // No C code needed.
import "C"
import "fmt"
var V int
func F() { fmt.Printf("Hello, number %d\n", V) }
Now, I have a "plugin manager" , pluginmanager/pluginmanager.go
package pluginmanager
import "plugin"
func Load(path string) {
p, err := plugin.Open(path)
if err != nil {
panic(err)
}
f, err := p.Lookup("F")
if err != nil {
panic(err)
}
f.(func())()
}
And finally, my main.go program
package main
import (
"path/to/my/pluginmanager"
"plugin"
)
func main() {
pluginmanager.Load("exampleplugin/exampleplugin.so")
}
This doesn't work and shows the error : plugin.Open: plugin was built with
a different version of package runtime
Sometimes, instead of runtime it shows another package, like math, errors,
...
BUT, if I load the plugin in the main.go program... it works:
package main
import (
"path/to/my/pluginmanager"
"plugin"
)
func main() {
plugin.Open("exampleplugin/exampleplugin.so")
pluginmanager.Load("exampleplugin/exampleplugin.so")
}
This works as expected, and exampleplugin.F() is called. I'm not sure what
I'm doing wrong or if I missed something. I'm using : go version devel

Also, I kind of understand that the plugin and the main program should use
the same version of a package, very limiting, since you may not know which
version a plugin used, but it's ok. Or is there any other way to do it?
