Trouble with intallation of OMNET++. After running the mingenv file. I run the make command but I got this error and do not know what it means

clistener.cc

I run this command

/c/OM++/omnetpp-6.0.3-windows-x86_64/omnetpp-6.0.3$ make

These are warnings, you should be able to execute OMNeT++.
If you want to fix this, replace clang=no at config.user file into main OMNeT++ directory. Thanks
