控制台编译，少不了使用：go build，用法:
usage: go build [-o output] [-i] [build flags] [packages]
根据输入的包之间的依赖性，编译包，但并不会将编译的结果进行安装。如果编译的参数是一系列的*.go文件，build命令视这些文件在一个包中。当编译一个main包时，build命令会将编译的可执行结果放入第一个go文件名（无后缀.go）中(如：’go build ed.go rx.go’ 编译后的可执行文件为’ed’或者’ed.exe‘，后者为windows系统的文件名 )，当编译的参数是一个目录而不是一系列go文件时，build命令生产的可执行文件名为目录名 (‘go build unix/sam’ writes ‘sam’ or ‘sam.exe’)。
当编译多个包或一个非main包时，build命令编译包并丢弃编译结果，只是检查是否能够被编译。
当编译包时，build会忽略*_test.go文件；
-o参数，只被允许在编译一个单独包时使用，并且强制将编译的可执行文件或object写入户名的文件名中。
-i参数，安装依赖于目标的包
build flag在build、clean、get、install、list、run、test命令中通用。
-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 programs, such as build commands or
test binaries, that can be run in parallel.
The build flags are shared by the build, clean, get, install, list, 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 programs, such as build commands or
test binaries, that can be run in parallel.
The default is the number of CPUs available.
-race
enable data race detection.
Supported only on linux/amd64, freebsd/amd64, darwin/amd64 and windows/amd64.
-msan
enable interoperation with memory sanitizer.
Supported only on linux/amd64,
and only with Clang/LLVM as the host C compiler.
-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.
针对-gcflags的值可使用go tool compile查看
The ‘go build’ and ‘go install’ commands take a -buildmode argument which
indicates which kind of object file is to be built. Currently supported values
are:
-buildmode=archive
Build the listed non-main packages into .a files. Packages named
main are ignored.
-buildmode=c-archive
Build the listed main package, plus all packages it imports,
into a C archive file. The only callable symbols will be those
functions exported using a cgo //export comment. Requires
exactly one main package to be listed.
-buildmode=c-shared
Build the listed main packages, plus all packages that they
import, into C shared libraries. The only callable symbols will
be those functions exported using a cgo //export comment.
Non-main packages are ignored.
-buildmode=default
Listed main packages are built into executables and listed
non-main packages are built into .a files (the default
behavior).
-buildmode=shared
Combine all the listed non-main packages into a single shared
library that will be used when building with the -linkshared
option. Packages named main are ignored.
-buildmode=exe
Build the listed main packages and everything they import into
executables. Packages not named main are ignored.
-buildmode=pie
Build the listed main packages and everything they import into
position independent executables (PIE). Packages not named
main are ignored.
-buildmode=plugin
Build the listed main packages, plus all packages that they
import, into a Go plugin. Packages not named main are ignored.
