我正在做一个测试:比较cgo和纯Go函数的执行时间，每个函数运行1亿次。与Golang函数相比，cgo函数需要更长的时间，我对这个结果感到困惑。我的测试代码是:packagemainimport("fmt""time")/*#include#include#includevoidshow(){}*///#cgoLDFLAGS:-lstdc++import"C"//import"fmt"funcshow(){}funcmain(){now:=time.Now()fori:=0;i结果是:cgoshowfunctionelasped0.368096minutesorelapsed22.08

我的程序与go1.4.2完美构建。安装go1.5后，出现以下错误。importsruntime:CsourcefilesnotallowedwhennotusingcgoorSWIG:atomic_amd64x.cdefs.cfloat.cheapdump.clfstack.cmalloc.cmcache.cmcentral.cmem_linux.cmfixalloc.cmgc0.cmheap.cmsize.cos_linux.cpanic.cparfor.cproc.cruntime.csignal.csignal_amd64x.csignal_unix.cstack.cstring
