Where did you get buildmode=dll from? As far as I can tell the arg is still buildmode=c-shared

@AlexRouSg
It's mentioned in the issue #11058, but it's not in Go help.

You can use go help buildmode to get this info:

I think you are mistaking a suggestion for the actual implementation. Nowhere is buildmode=dll mentioned as being added.

Even in that issue, they used buildmode=c-shared to create dlls.

So, how do I make a DLL?

As I've said in both replies, use buildmode=c-shared

I am getting this:

C:\Users\Muzzammil\sdk\go1.10rc1\pkg\tool\windows_amd64\link.exe: running gcc failed: exec: "gcc": executable file not found in %PATH%

You need to install mingw

For questions please use https://github.com/golang/go/wiki/Questions

Now I am getting this:

C:\Users\Muzzammil\sdk\go1.10rc1\pkg\tool\windows_amd64\link.exe: running gcc failed: exit status 1
C:\Users\MUZZAM~1\AppData\Local\Temp\go-link-763910195\go.o: file not recognized: File format not recognized
collect2.exe: error: ld returned 1 exit status

Thank you @AlexRouSg, I thought that -buildmode=dll was a thing.

You need mingw-64. I just was able to link an amd64 DLL using that.

Thanks @hank

@AlexRouSg
It only generate .a libray by buildmode=c-shared, and it can not be used in VC porject
