This page documents the builtin golang compilation tools.
go's build/install/clean aim to replace (or dramatically simplify) a Makefile.
run
go run
is a convenience tool that builds/runs an executable.go run . # compile package at cwd, and run it's 'main()' method go run . --help # cli params for the program can be passed to go run go run main.go lib.go ... # compile only these files, and run detected 'main()' method go run some/package # compile a specific packageIt accepts all of the same build-flags as
go build
,
which includes some validation tools.go run -race . # compile/run, and detect race conditions
build
Basics
Go build creates an executable with the name of your package.
If your package includes slashes, it is only the basename.
(ex: package:example.com/x/foo
creates executablefoo
)go build # build executable for package at cwd go build -a # force rebuild executable, even when up to date go build -o altname # build executable as 'altname'
go clean
andgo install
are used similar to a makefile for cleaning builds, and installing to host os (see below).Cross Compilation
GOOS=darwin GOARCH=386 go build # build for macos GOOS=windows GOARCH=386 go build # build for windowsTools
go build \ -race `# detect race-conditions` \
clean
go clean # removes build go clean -i # removes 'go install'ed executable go clean -x # print commands as deletes
