Question

我正在尝试在Omnet ++ 4.2.2中使用LEDA-6.3库。我安装了LEDA并运行了一个简单的程序，使用它没有Ubuntu终端的问题。但是，当我将代码移植到Omnet ++时，它失败了。下面是我的简单代码。

    #include <LEDA/graph/graph.h>
    #include <omnetpp.h>

    class cLeda : public cSimpleModule
    {
      protected:
        virtual void initialize();
    };

    Define_Module(cLeda);

    void cLeda::initialize()
    {
        EV << "TestLEDA";
        graph g;
        g.read("nsfnet.txt");
        EV << "No. nodes = " <<g.number_of_nodes() << endl;
    }

我为编译器和链接器配置了LEDA路径，如下所示：Project - ＆gt;属性 - ＆gt;选择C / C ++一般 - ＆gt;路径和符号并添加：

图书馆路径：/home/grsst/LEDA-6.3/incl
对于图书馆：/home/grsst/LEDA-6.3/libleda.a（我没有添加libleda.o 因为即使使用Ubuntu命令行它也不起作用）
对于图书馆路径：/home/grsst/LEDA-6.3

编译时，我得到的错误如下：

   Description  Resource    Path    Location    Type
   make: *** [all] Error 2  TestLeda            C/C++ Problem
   make[1]: *** [../out/gcc-debug/src/TestLeda] Error 1 TestLeda            C/C++ Problem

我很感激能帮助我让它发挥作用。万分感谢。

    INCLUDE_PATH += -I/home/grsst/LEDA-6.3/incl
    LIBS += -L/home/grsst/LEDA-6.3  -lleda

如何在Omnet ++项目中使用LEDA图形库？
