NAME¶

go - tool for managing Go source code

SYNOPSIS¶

go build [-o output] [ build flags ] [ packages ]

DESCRIPTION¶

Build compiles the packages named by the import paths, along with their dependencies, but it does not install the results.

If the arguments are a list of .go files, build treats them as a list of source files specifying a single package.

When the command line specifies a single main package, build writes the resulting executable to output. Otherwise build compiles the packages but discards the results, serving only as a check that the packages can be built.

The -o flag specifies the output file name. If not specified, the name is packagename.a (for a non-main package) or the base name of the first source file (for a main package).

OPTIONS¶

The build flags are shared by the build, install, run, and test commands:

-a

force rebuilding of packages that are already up-to-date.

-n

print the commands but do not run them.

-p n

the number of builds that can be run in parallel. The default is the number of CPUs available.

-v

print the names of packages as they are compiled.

-work

print the name of the temporary work directory and do not delete it when exiting.

-x

print the commands.

-compiler name

name of compiler to use, as in runtime.Compiler (gccgo or gc)

-gccgoflags 'arg list'

arguments to pass on each gccgo compiler/linker invocation

-gcflags 'arg list'

arguments to pass on each 5g, 6g, or 8g compiler invocation

-ldflags 'flag list'

arguments to pass on each 5l, 6l, or 8l linker invocation

-tags 'tag list'

a list of build tags to consider satisfied during the build. See the documentation for the go/build package for more information about build tags.

For more about specifying packages, see go-packages(7).

For more about where packages and binaries are installed, see go-gopath(1).
