Q：grdp库无法打包，出现如下报错

Wails CLI v2.7.1

Executing: go mod tidy
• Generating bindings: 
ERROR  
package slack-wails
 imports slack-wails/core/portscan

 imports github.com/tomatome/grdp/protocol/t125/gcc
 imports github.com/tomatome/grdp/plugin: build constraints exclude all Go files in C:\xx\go\pkg\mod\github.com\tomatome\[email protected]\plugin

A：检查GCC环境环境是否安装，可以通过命令行输入gcc查看命令提示

1、查看文档上方安装教程
2、go env查看CGO_ENABLED是否为1，若不是则go env -w CGO_ENABLED=1
