Question

我的文件夹中只有2个文件 - Gnuplot_example.cpp和Makefile。

Gnuplot_example.cpp

#include "Snap.h"
int main(int argc, char* argv[]) {
TIntH expCount, PoissonCount;
TRnd a;
double binSize=0.1;
//exponential distribution  
for (int i=0; i<10000; ++i)
{
    double num=a.GetExpDev(1);
    expCount.AddDat((int)(num/binSize))++;
}

//Poisson distribution  
for (int i=0; i<10000; ++i)
{
    double num=a.GetPoissonDev(10);
    PoissonCount.AddDat((int)(num/binSize))++;
}


expCount.Sort(true,true);
PoissonCount.Sort(true,true);

{
    TVec<TPair<TFlt, TFlt > > XY1, XY2;
    for (int i=0; i<expCount.Len(); ++i)
        XY1.Add(TFltPr(expCount.GetKey(i)*binSize, expCount[i]+0.0));
    for (int i=0; i<PoissonCount.Len(); ++i)
           XY2.Add(TFltPr(PoissonCount.GetKey(i)*binSize,PoissonCount[i]+0.0));
    TGnuPlot Gp("distribution", "Exponential and Poisson Distribution");
    Gp.AddPlot(XY1, gpwLinesPoints, "Exponential");
    Gp.AddPlot(XY2, gpwLinesPoints, "Poisson");
    Gp.SetXYLabel("value", "count");
    Gp.SavePng(); //or Gp.SaveEps();
}

return 0;
}

rm -rf Debug Release

当我在此文件夹中使用命令'make'时，它说： make：'all'没什么可做的。并且没有创建目标文件。我已经完成了其他答案，并确保在规则中使用制表符而不是空格。我是新来的。我没有弄错。感谢您的帮助!!

make：'all'无所事事
