在omnet++中构建项目时出错

Question

在构建导入的项目时，会发生错误。我正在使用gcc版本9。

我已经成功地建立了Inet4.1。我也尝试了一些gcc版本在5到8之间，但也发生了同样的错误。

Answer 1

您或任何编写头文件model/Showcase/Layer1/DummyWindPark/WindPowerGenerator.h的人都试图在该文件中使用IntType = double实例化模板template< class IntType = int >class uniform_int_distribution，编译器注意到：

In instantiation of ‘class std::uniform_int_distribution<double>’

double不是一个整体类型，模板包含一个static_assert，要求IntType是一个整体类型。因此，static_assert作为编译时失败：

 error: static assertion failed: template argument must be an integral type

整数类型是那些满足模板谓词std::is_integral的类型。

如果您或失败std::uniform_int_distribution<double>的作者想要生成一个统一的double分布，那么他们应该使用template< class RealType = double > class uniform_real_distribution
