Veins_inet: undefined reference to `__imp__ZTVN5Veins17VeinsInetMobilityE' when building in OMNet 5.1.1

I imported veins_inet subproject into OMNet 5.1.1 on Windows-64 machine and tried to build. Everything went okay (building inet and veins) until receiving this error when it starts building veins_inet:

I tried using gcc-release instead of gcc-debug but the problem stays. Any help please? Thanks.

You may check your VeinsInetMobility.h if there is class INET_API xx : public. The "without dllimport attribute" warning and "undefined reference" error may be caused by "INET_API" in some omnet windows edition. You can just remove "INET_API" to see if it is OK. Just for advice.

As you said, it definitely looks like a Windows issue. Today i got exactly the same error, when building veins_inet under Windows for the first time. Last month I was forced to reinstall my Linux (Ubuntu 16.04 64-bit) workstation several times and never had the same issue - it compiled flawlessly.
