## 进一步了解 Go 构建 如果要了解执行`go build`命令之后的更多信息，则应在其中添加`-x`标志： ```shell $ go build -x defer.go WORK=/var/folders/sk/ltk8cnw50lzdtr2hxcj5sv2m0000gn/T/go-build254573394 mkdir -p $WORK/b001/ cat >$WORK/b001/importcfg.link << 'EOF' # internal packagefile command-line-arguments=/Users/mtsouk/Library/Caches/go- build/9d/9d6ca8651e083f3662adf82bb90a00837fc76f55839e65c7107bb55fcab92458-d packagefile fmt=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/fmt.a packagefile runtime=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/runtime.a packagefile errors=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/errors.a packagefile io=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/io.a packagefile math=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/math.a packagefile os=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/os.a packagefile reflect=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/reflect.a packagefile strconv=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/strconv.a packagefile sync=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/sync.a packagefile unicode/utf8=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/unicode/u tf8.a packagefile internal/bytealg=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/inter nal/bytealg.a packagefile internal/cpu=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/internal/ cpu.a packagefile runtime/internal/atomic=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd6 4/runtime/internal/atomic.a packagefile runtime/internal/sys=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/r untime/internal/sys.a packagefile sync/atomic=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/sync/atomi c.a packagefile internal/poll=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/internal /poll.a packagefile internal/syscall/unix=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/ internal/syscall/unix.a packagefile internal/testlog=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/inter nal/testlog.a packagefile syscall=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/syscall.a packagefile time=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/time.a packagefile unicode=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/unicode.a packagefile math/bits=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/math/bits.a packagefile internal/race=/usr/local/Cellar/go/1.11.4/libexec/pkg/darwin_amd64/internal /race.a EOF mkdir -p $WORK/b001/exe/ cd . /usr/local/Cellar/go/1.11.4/libexec/pkg/tool/darwin_amd64/link -o $WORK/b001/exe/a.out -importcfg $WORK/b001/importcfg.link -buildmode=exe - buildid=nkFdi6n3HGYZXDdCOju1/VfKOjehfe3PSzik3cZom/OthUDj9rThOtZPf-2627/nkFd i6n3HGYZXDdCOju1 -extld=clang /Users/mtsouk/Library/Caches/go- build/9d/9d6ca8651e083f3662adf82bb90a00837fc76f55839e65c7107bb55fcab92458-d /usr/local/Cellar/go/1.11.4/libexec/pkg/tool/darwin_amd64/buildid -w $WORK/b001/exe/a.out # internal mv $WORK/b001/exe/a.out defer rm -r $WORK/b001/ ``` 虽然了解编译的详细过程对你说是好事，但是大多数情况下你都不需要了解这些详细的编译过程信息。
