need help for editing a makefile

[mahmoodn]

Hi,
I have these lines in makefile:
VVc_demo.moc:  VVc_demo.cpp

	$(QT_MOC) -o VVc_demo.moc  VVc_demo.cpp



VVc_demo$(OBJ_EXT): VVc_demo.moc



VVc_demo$(EXE_EXT): VVc_demo$(OBJ_EXT)

	$(CGAL_CXX) $(LIBPATH) $(EXE_OPT)VVc_demo VVc_demo$(OBJ_EXT) $(LDFLAGS)


I want to tell make that compile VVc_demo.cpp whenever "a.cpp" or "b.cpp" or
"c.cpp" or ... changed.
How can I do that?

VVc_demo$(OBJ_EXT) : a.cpp b.cpp c.cpp
  g++ -o $@ -c VVc_demo.cpp

(Usually you'd add VVc_demo.cpp itself to the dependency list as well.)

HTH,

Hello,

Thanks but I forgot to say that there are some .h files too (it was my
fault). I add some thing like this:

VVc_demo.moc:  VVc_demo.cpp

	$(QT_MOC) -o VVc_demo.moc  VVc_demo.cpp



VVc_demo$(OBJ_EXT): VVc_demo.moc VVc_diagram_2.h Polygon_Voronoi_diagram_2.h 

	g++ -o $@ -c VVc_demo.cpp 


VVc_demo$(EXE_EXT): VVc_demo$(OBJ_EXT)

	$(CGAL_CXX) $(LIBPATH) $(EXE_OPT)VVc_demo VVc_demo$(OBJ_EXT) $(LDFLAGS)


but it says:
[mahmood@Milky-way VVc_diagram_2]$ make
make: *** No rule to make target `VVc_diagram_2.h', needed by `VVc_demo.o'. 
Stop.

What should I do now?

Add the include file path  -Iyourpath to that step,, just as you would
do when compiling outside make.  -I./ normally is there by default.

Hi,

you mean this (?):
VVc_demo.moc:  VVc_demo.cpp

	$(QT_MOC) -o VVc_demo.moc  VVc_demo.cpp



VVc_demo$(OBJ_EXT): VVc_demo.moc


           -I../../include \

           -I../../../Arrangement_2/include \

VVc_demo$(EXE_EXT): VVc_demo$(OBJ_EXT)

	$(CGAL_CXX) $(LIBPATH) $(EXE_OPT)VVc_demo VVc_demo$(OBJ_EXT) $(LDFLAGS)



and compiler and linker flags are:
CXXFLAGS = \

           -I../../include \

           -I../../../Arrangement_2/include \

           -DNDEBUG \

           $(CGAL_CXXFLAGS) \

           $(LONG_NAME_PROBLEM_CXXFLAGS)



#---------------------------------------------------------------------#

#                    linker flags

#---------------------------------------------------------------------#



LIBPATH = \

          $(CGAL_LIBPATH)



LDFLAGS = \

          $(LONG_NAME_PROBLEM_LDFLAGS) \

          $(CGAL_QT_LDFLAGS)



Thanks,
