All .cpp files depend on two .h files?
In the makefile, I have the following line:
helper.cpp: dtds.h
This will ensure that helper.cpp is restored when dtds.h changes. However, I want ALL files in the project to be rebuilt if one of the other two header files changes, like this:
*.cpp: h1.h h2.h
Obviously this won't work, but I don't know how to properly get nmake to do what I want. Can anyone please help? I don't want to manually specify that every single file depends on h1.h and h2.h.
Thank. (I am using nmake included in visual studio 2005.)

Thanks for your help Christophe. I tried:
.cpp.obj: h1.h h2.h
And got a helpful error message:
makefile(58) : fatal error U1086: inference rule cannot have dependents
I solved this by making a list of the files that I wanted to compile and then adding the dependency to the entire list.
files = file1.obj file2.obj file3.obj $ (files): h1.h h2.h

Try
%.cpp : h1.h h2.h
This works in GNU make - don't know if nmake is compatible ...
Edit: And btw: shouldn't be
helper.o : dtds.h
%.o : h1.h h2.h
After all, you don't want to remake the file .cpp
(how to create the original file?), But recompile ...
Edit2: Check NMAKE Help . According to this , something like
.cpp.obj: h1.h h2.h
can work...
