That means the linking is being done for a GUI application.  I guess you
wanted to build a console application, so you should learn what these
options for the linker mean:


There are equivalent options used with the compiler g++, I think they are:


In general there are many options that apply only to Windows builds, for
instance building Qt GUI applications I use these for the linker:

-Wl,-enable-stdcall-fixup -Wl,-enable-auto-import
-Wl,-enable-runtime-pseudo-reloc -Wl,-as-needed

but they are not for solving linking errors, just to quiet the warnings,
and try to optimize the result.
