Question

在构建导入的项目时，会发生错误。我正在使用gcc版本9。

我已经成功构建了Inet 4.1。我也尝试使用5到8之间的其他gcc版本进行此操作，但是发生了相同的错误。

Answer 1

您，或者是写头文件model/Showcase/Layer1/DummyWindPark/WindPowerGenerator.h的人，正在尝试在该文件中实例化模板template< class IntType = int >class uniform_int_distribution 编译器指出，IntType = double

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

double不是整数类型，并且模板包含static_assert 要求IntType 是整数类型。这样static_assert的编译时间就会失败：

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

整数类型是满足模板谓词std::is_integral的那些类型。

如果您或失败的std::uniform_int_distribution<double>的作者希望生成 double的均匀分布，那么他们应该使用template< class RealType = double > class uniform_real_distribution

在omnet ++中构建项目时出错
