Re: "Batch-Mode" rules with Microsoft compile

[John Skiff]

Paul,

What you suggest does work.  I had an additional item which was making
it fail.  Boiled down I have something like the following:

CXX = Cl
CXXFLAGS = -GR -vmm -D_MT -Zi -Od -D_DEBUG -MTd -GZ -FD

ifndef CCSRC
CCSRC := $(wildcard *.cpp)
endif

ifndef CCOBJ
CCOBJ := $(CCSRC:%.cpp=%.obj)
endif

LINKOPTIONS =/nologo /machine:ix86 

ev_addpath.exe: $(CCOBJ)

$(CCOBJ): $(CCSRC)
        $(CXX) $(CXXFLAGS) -c $?
        link $(LINKOPTIONS) /out:ev_addpath.exe $(CCOBJ)

The purpose of $CCOBJ was to make it possible to force a rebuild by
removing a .obj file.  However if I remove one .obj file then ALL of the
source recompiles.  I guess that there is no way around that.  If you
can think of a way please let me know.

Thanks for helping me to clear this up,
John
