go - tool for managing Go source code
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
- 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.
