Compile Go sources.
Compile a 'package main' file (output will be the filename without extension)
Compile, specifying the output filename
Compile a package
Compile a main package into an executable, enabling data race detection
go build [ -o output ] [ 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 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).
The build flags are shared by the build, install, run, and test commands:
force rebuilding of packages that are already up-to-date.
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.
print the names of packages as they are compiled.
print the name of the temporary work directory and do not delete it when exiting.
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 where packages and binaries are installed, see go-gopath(1).
