Veins_inet：在OMNet 5.1.1中构建时未定义对"__imp__ZTVN5Veins17VeinsInetMobilityE"的引用

Question

i i导入Windows-64机器上的Omnet 5.1.1并尝试构建的Omnet 5.1.1。一切正常（构建INET和静脉），直到开始构建Veines_inet时收到此错误：

我尝试使用GCC释放而不是GCC释放，但问题仍然存在。有帮助吗？谢谢。

正如您所说的，它绝对看起来像是Windows问题。今天，当我第一次在Windows下构建Veins_inet时，我遇到了完全相同的错误。上个月，我被迫重新安装我的Linux（Ubuntu 16.04 64位）工作站，但从未遇到过同样的问题 - 它完美地编译了。

您可以检查您的静脉漏洞。在某些Omnet Windows Edition中，"无dllimport属性"警告和"未定义的参考"错误可能是由" Inet_api"引起的。您只需删除" inet_api"即可查看是否还可以。只是为了建议。
