Does it work if you do everything natively on Windows? That is, is this a problem with Windows DLLs, or is this a problem with using a cross-compiler from MacOS? How exactly are you trying to use the generated DLL? Simply running it is not expected to work. You are expected to open it from a C program. You are likely to get better answers for this on a forum; see https://golang.org/wiki/Questions . |
