我在 golang 中有一些 Linux 代码:
import "syscall"
var info syscall.Sysinfo_t
err := syscall.Sysinfo(&info)
totalRam := info.Totalram

我想将其移植到 Mac OS X。我看到 Sysinfo 在 Linux 上可用,但在 Mac 上不可用:
Linux:
$ go list -f '{{.GoFiles}}' syscall | sed -e "s/[][]//g" | xargs fgrep --color -Iwn Sysinfo
syscall_linux.go:962://sysnb Sysinfo(info *Sysinfo_t) (err error)
zsyscall_linux_amd64.go:822:func Sysinfo(info *Sysinfo_t) (err error) {\

苹果电脑:
$ go list -f '{{.GoFiles}}' syscall | sed -e "s/[][]//g" | xargs fgrep --color -Iwn Sysinfo
# No results

在 Mac 上获取系统 RAM 信息的正确方法是什么?
此代码支持交叉编译。
先决条件:
package main
import (
"fmt"
"log"
"os"
"runtime"
"strconv"
"github.com/shirou/gopsutil/mem"
)
func errHandler(err error) {
if err != nil {
log.Println(err.Error())
os.Exit(1)
}
}
func main() {
runtimeOS := runtime.GOOS
runtimeARCH := runtime.GOARCH
fmt.Println("OS: ", runtimeOS)
fmt.Println("Architecture: ", runtimeARCH)
vmStat, err := mem.VirtualMemory()
errHandler(err)
fmt.Println("Total memory: ", strconv.FormatUint(vmStat.Total/(1024*1024), 10)+" MB")
fmt.Println("Free memory: ", strconv.FormatUint(vmStat.Free/(1024*1024), 10)+" MB")
// Cached and swap memory are ignored. Should be considered to get the understanding of the used %
fmt.Println("Percentage used memory: ", strconv.FormatFloat(vmStat.UsedPercent, 'f', 2, 64)+"%")
}
