努普洛&C ++:在PATH和"quot;"中均找不到gnuplot [英] Gnuplot & C++: Can't find gnuplot neither in PATH nor in "

问题描述

我正在Windows上使用gnuplot_i.hpp使用Gnuplot.当我在cmd中键入"gnuplot"时，一切正常，因此应正确设置PATH变量.这是我的代码:

  #include< iostream>#include"gnuplot_i.hpp"使用std :: cout;使用std :: endl;int main(int argc，char * argv []){尝试 {Gnuplot g1("lines");} catch(GnuplotException ge){cout<<ge.what()<<恩德尔}返回0;} 

输出是PATH和"C:/program files/gnuplot/bin"都找不到gnuplot.

添加行时

  Gnuplot :: set_GNUPlotPath("C:/gnuplot/bin/"); 

它更改为在PATH和"中都找不到gnuplot.

我在做什么错了?

解决方案

我自己找到了答案:由于某些原因，gnuplot_i.hpp希望您的exe名为pgnuplot.exe而不是gnuplot.exe ...现在一切正常./p>

I am trying to use Gnuplot on Windows with gnuplot_i.hpp. When I type "gnuplot" into cmd everthing works, so the PATH variable should be set correctly. This is my code:

#include <iostream>
#include "gnuplot_i.hpp"
using std::cout;
using std::endl;

int main(int argc, char* argv[]) {
    try {
        Gnuplot g1("lines");
    } catch (GnuplotException ge) {
        cout << ge.what() << endl;
    }
    return 0;
}

The output is Can't find gnuplot neither in PATH nor in "C:/program files/gnuplot/bin" .

When I add the line

Gnuplot::set_GNUPlotPath("C:/gnuplot/bin/");

it just changes to Can't find gnuplot neither in PATH nor in "".

What am I doing wrong here?

解决方案

Found the answer myself: For some reason gnuplot_i.hpp expects your exe to be called pgnuplot.exe instead of gnuplot.exe ... Now everything works.
