If you're going to try to cross-compile, you need to point at the Windows MQ client include/library directories. Look at ibmmq/mqi.go for the usual LDFLAGS/CFLAGS needed for Windows. And then you'd have to map your Windows MQ installation directory to however WSL sees it. Though I've not tried cross-compiles, so don't know how successful it might be.

Thanks Mark
I tried from a Windows system, but I am getting the below errors ...not sure if I'm doing something wrong, can you guide me

[ibmmqmet]

That looks like you're mixing up powershell and traditional command prompt operations.

Thanks again Mark! ... Indeed I was mixing up PS and command prompt. I was able to do a windows build , but getting a new blocker now ...am I missing any thing ?

These are the Flags I'm using

Did you install mqm on windows machine? if it's installed check all path and ensure it contains path to dll
It's all about dynamic linking
