[vtkusers] what's meaning of "-mwin32 -mthreads -mwindows"

[Bangyou Zheng]

Hello all,

I juse download the vtk minimal sample from 
"http://code.hkpeterpeter.googlepages.com/vtk_minimal_mingw.zip"

But I can not understand the linked libraries, for example -mwin32 
-mthreads -mwindows.

Do you have any suggestion?

This is the makefile:

CC = gcc
CXXFLAGS = -Wno-deprecated
INC = -I"D:\SourceCode\Libraries\VTK\scr\include\vtk-5.0"
LIB = -L"D:\SourceCode\Libraries\VTK\scr\lib" -mwin32 -mthreads 
-mwindows -lvtkRendering -lvtkGraphics -lvtkImaging -lvtkIO 
-lvtkFiltering -lvtkCommon -lvtkftgl -lvtkfreetype -lopengl32 
-lvtkDICOMParser -lvtkpng -lvtktiff -lvtkzlib -lvtkjpeg -lvtkexpat 
-lvfw32 -lvtksys -lgdi32 -lstdc++

minimal: vtk_minimal.cpp
gcc $(CXXFLAGS) -c vtk_minimal.cpp $(INC)
gcc -o minimal vtk_minimal.o $(LIB)

clean:
rm -f *.o minimal.exe



Best regards,
