如何在Omnet ++项目上使用LEDA图形库?

问题描述

我正在尝试在Omnet ++ 4.2.2中使用LEDA-6.3库.我安装了LEDA，并在Ubuntu终端上使用它运行了一个简单的程序，没有任何问题.但是，当我将代码移植到Omnet ++时，它将失败.下面是我的简单代码.

I am trying to use LEDA-6.3 library in Omnet++ 4.2.2. I installed LEDA and ran a simple program using it without problem from Ubuntu terminal. However, when I port the code to Omnet++, it fails. Below is my simple code.

    #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:项目->属性->选择C/C ++常规->路径和符号并添加:

I configured for LEDA paths for compiler and linker as follows: Project -> Properties --> Choose C/C++ General -> Path and Symbols and added:

• 对于库路径:/home/grsst/LEDA-6.3/incl
• 对于库:/home/grsst/LEDA-6.3/libleda.a(我没有添加libleda.o因为它甚至在Ubuntu命令行中也无法使用)
• 对于库路径:/home/grsst/LEDA-6.3

• For Library Paths: /home/grsst/LEDA-6.3/incl
• For Libraries: /home/grsst/LEDA-6.3/libleda.a (I didn't add libleda.osince it doesn't work even with Ubuntu command line)
• For Library Paths: /home/grsst/LEDA-6.3

编译时，出现如下错误:

When I compile, the I got errors as follows:

   make: *** [all] Error 2  TestLeda            C/C++ Problem

我非常感谢有任何想法可以帮助我实现这一目标.谢谢你一百万.

I appreciate any idea to help me to make it work. Thanks a million.

推荐答案

OMNeT++项目通常使用Makefile.尝试将LEDA库添加为Makefrag.转到Project Properties，选择OMNeT++ |. Makemake |选择src | Options | Custom | Makefrag并写:

OMNeT++ project usually uses Makefile. Try to add LEDA libraries as a Makefrag.Go to Project Properties, choose OMNeT++ | Makemake | select src | Options | Custom | Makefrag and write:

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