get started

brew install go

cd ~/go

make sure bin, pkg and src 3 paths in ~/go, create dir if not exists

vim ~/.zshrc

export GOPATH=~/go
export GOROOT=/usr/local/go
PATH="${GOPATH}/bin:${PATH}"
export PATH

mkdir a new project like ~/go/src/demoProject

then execute command go mod init demoProject

using install instead of get in command, like go get ..., please use go install ....

then it will download exe file in ~/go/bin

windows

基本的

GOOS=windows GOARCH=amd64 go build -o bin/app-amd64.exe app.go

GOOS=windows GOARCH=386 go build -o bin/app-386.exe app.go

cross platform compile

GOOS=windows GOARCH=amd64 CGO_ENABLED=1 go build -o bin/app-386.exe main.go

error info: gcc_libinit_windows.c:7:10: fatal error: 'windows.h' file not found

brew install mingw-w64

add /usr/local/Cellar/mingw-w64/10.0.0_3/bin to PATH

将-buildmode=c-archive改为-buildmode=c-shared即可

mac

GOOS=darwin GOARCH=amd64 go build -o bin/app-amd64-darwin app.go

GOOS=darwin GOARCH=386 go build -o bin/app-386-darwin app.go

after build, rename app to app.app, app.app will not open console

linux

GOOS=linux GOARCH=amd64 go build -o bin/app-amd64-linux app.go

GOOS=linux GOARCH=386 go build -o bin/app-386-linux app.go
