Questa Sim on Windows - linking to external LIB

I have been trying to use Questa (from Quartus Lite 21.1) on Windows to link to the Winsock2 library, without success. I have a minimal test case attached. I can't get it to load into the simulator...

    I believe we have figured it out. We needed to add the -64 parameter, and -ldflags to pass parameters to gcc. This appears to work:

    vsim -c DPI_test -ldflags "-lws2_32" -64

Seems like some compatibility issue there. Winsock library is 32-bit version but questa gcc is 64-bit version. Try to use modelsim instead of questa in order to match bit version.
