Why do I get a build error when trying to build Veins VLC on OMNeT++?

Question

I'm trying to build veins-vlc module on Omnet++ but I keep getting the following error.

make MODE=debug all 
make[1]: Entering directory '/c/Users/uthpa/Documents/OMNET++/omnetpp-5.7/workspace/veins_vlc-master/src'

I have already imported veins and built it without issues. I use omnetpp 5.7, veins 5.2 and veins-vlc 1.0 versions. Please help.

it is written here that for Windows it is necessary to install OMNeT++ 6.0 or use gcc instead of clang. Cite:

Note that, on Windows, using Veins with other module libraries (such as the INET Framework, via veins_inet) is only supported for OMNeT++ 6.0pre14 (or OMNeT++ 5.6.2 when using the non-clang toolchain)
