When I call syscall.LoadDLL("my.dll") in my notebook, it works well.
But when I copy the execution file (.exe) and my.dll to other computers, it will fail and show the following error:
Failed to load my.dll: The specified module could not be found.
The my.dll could be found in the same directory.
I don't know what happened.
Your .DLL probably depends on some other .DLL not installed on these other systems. Dependency Walker is a useful tool to debug these types of issues...
