Trying to test it at Windows, but got:

What compiler are you using? The MinGW-w64 should have fteli64, also recent MinGW from mingw.org.

mmm, May I did not understand the installation, just having Go1.16.6 and run go get ... command!
Do I need to do some other things?

[gen2brain]

See https://golang.org/cmd/cgo/ and e.g https://dave.cheney.net/2016/01/18/cgo-is-not-go.

Trying to understanding, this is something completely new for me, if you can add some more explanation in the required installation/build, it will be great help. thanks

[gen2brain]

The instructions are the same for every project that uses C libraries, you need a C compiler installed, like Mingw-w64 or TDM-GCC.

[gen2brain]

When I tested other projects in Windows, the easiest for me was to install TDM-GCC, of course in Linux everything is much simpler to install/configure.

Thanks a lot, I installed tdm-gcc and things are great now, I would recommend you add small note about this in the installation section, I expect not to be the only who do not this :)
