I have referred msvc/Makefile. From the description "$(LD) /entry:mainCRTStartup" in it, I have used -Wl,-emainCRTStartup flag. I deleted this flag and I can see qt terminal plot but it is insufficient.
See:

On the command line I found the message:
gnuplot> plot sin(x)
Warning: slow font initializationqt_processTermEvent received a GE_fontprops eve
nt. This should not have happened.
Any suggestions?
