安装网络模拟器时出错

Question

ns2.34大家好，我在 Fedora 中安装时遇到以下错误。

请帮我解决

collect2: ld returned 1 exit status
make: *** [Makefile:420: ns] Error 1
Ns make failed 

Answer 1

我想完整的错误是：

2. ERROR
tools/ranvar.cc: In member function ‘virtual double GammaRandomVariable::value()’:
tools/ranvar.cc:219:70: error: cannot call constructor ‘GammaRandomVariable::GammaRandomVariable’ directly [-fpermissive]
tools/ranvar.cc:219:70: error:   for a function-style cast, remove the redundant ‘::GammaRandomVariable’ [-fpermissive]
make: *** [tools/ranvar.o] Error 1

解决这个问题的方法是：

在ns-2.34/tools/ranvar.cc，第 219 行

代替

-return GammaRandomVariable::GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);

和

+return GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);
