CGo by Example for Windows

To run cgo on a Windows platform you will need a MinGW compiler. I strongly advise TDM-GCC-64, as it is cross-compliant for both GOARCH=amd64 and GOARCH=386. Here I will use this example

http://tdm-gcc.tdragon.net/

Compiling a cgo program requires a few environment variables:

set GOOS=windows
set GOARCH=amd64
set CGO_ENABLED=1

Unfortunately if you're working with mingw32-make, it doesn't seem to support .ONESHELL and if you have Git for Windows one-line solutions are also very fragile. The best solution I found to set these variables is batch files that wrap mingw32-make.

Usage

amd64.bat

main.exe

main2.exe

mingw32-make clean & 386.bat

main.exe

main2.exe
