Actually, it doesn't work on Linux either.

How did this problem ultimately be solved?

[lordspace]

Changed the logic of my app and didn't have to use this module.

Test gcc -v and go env | grep CGO_ENABLED in your enviroment.
I have met the same problems.
Reason:

• GCC is not installed
• Or GCC hasn't been added to the environment variable
• Or go env CGO_ENABLED=0

The solution is to install gcc and add it to the environment variable and set go env -w CGO_ENABLED=1. Refer to https://github.com/go-vgo/robotgo#requirements

By the way, I encountered another issue with Win+VSCode+Git Bash, where certain methods were showing as non-existent in the editor, while some others existed. The reason was that I added GCC to the PATH in Git Bash but not in the system, which caused gopls to be unable to resolve these methods. Add GCC to the system environment variable resolved the issue.

@wilon I try go env -w CGO_ENABLED=0，But still reporting an error

go env | grep CGO_ENABLED

use go env -w CGO_ENABLED=1

i build for windows in Ubuntu ,

sudo apt-get install mingw-w64

GOOS=windows GOARCH=amd64 CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ go build -o main.exe

it works
