I have included the
#include <portmidi.h>
#include <porttime.h>
libraries and everything compiles fine, but I get the following errors on runtime.

# github.com/rakyll/portmidi
could not determine kind of name for C.PmDeviceID
could not determine kind of name for C.PmError
could not determine kind of name for C.Pm_CountDevices
could not determine kind of name for C.Pm_GetDefaultInputDeviceID
could not determine kind of name for C.Pm_GetDefaultOutputDeviceID
could not determine kind of name for C.Pm_GetDeviceInfo
could not determine kind of name for C.Pm_Initialize
could not determine kind of name for C.Pm_Terminate
could not determine kind of name for C.Pt_Start
could not determine kind of name for C.Pt_Stop
could not determine kind of name for C.Pt_Time

Does anyone have any idea what this can come from?
Sorry if its a noob question, I'm pretty new to Go and thanks for help!
