build
Usage
$ go build ARGS
The build command will output to the current directory or a given target file path.
Unlike install this will not build to your GOBIN.
Help
$ go help build
usage: go build [-o output] [-i] [build flags] [packages]
Build compiles the packages named by the import paths,
along with their dependencies, but it does not install the results.
If the arguments to build are a list of .go files from a single directory,
build treats them as a list of source files specifying a single package.
...
Default output location
No module given
Given main.go in the top-level directory:
$ go build
The result will be files:
main.gomy-project- the outer directory will be used, such as your repo’s name.
Module given
Pass a script name and the name of the script will be used for output.
Given main.go in the top-level directory:
$ go build main.go
The result will be files:
main.gomain
Given main.go in a subdirectory:
$ go build cmd/myapp/main.go
The result will be files:
cmd/myapp/main.gomain
Custom output
Choose an output path.
The -o flag must come before the module names.
$ go build -o myapp main.go
Result:
main.gomyapp
Use a file path in subdirectory. This will be created for you.
$ go build -o build/myapp main.go
Result:
main.gobuild/myapp
