Make problem with MSVSC++

[W. Bauer]

Dear all

The following makefile

CXX= cl
CXXFLAGS = -c -O2
%.o : %.cc
$(CXX) $(CXXFLAGS) $*.cc
lib: cflow_irr.o
gives, when called with "make lib", the error

NMAKE : fatal error U1073: don't know how to make 'cflow_irr.o'
Using instead the explicit dependency
cflow_irr.o:
$(CXX) $(CXXFLAGS) cflow_irr.cc
it works. This is my first makefile problem, so I would appreciate any
hints. The problem is the more then 100 files need to get compiled.

I think that the syntax for NMAKE is completely different from the syntax
you are used to. But in any case for help with NMAKE ask on a Windows
programming group such as news:comp.os.ms-windows.programmer.tools.misc, or
maybe news:microsoft.public.vc.ide_general. You are off topic here.

But they'll probably tell you to forget about makefiles and create a project
instead.

I hope not.

This is a GNUism. The regular unix way to do this is*:
..cc.o:
$(CXX) $(CXXFLAGS) $<

you may also need to add a line: ".SUFFIXES: .cc .o", I do not remember
what the default list is supposed to be.

I do not know about nmake in particular, but you are more likely to have
the standard syntax work than an extension.

If so, you can find information about NMAKE at
www.msdn.microsoft.com

Many thanks, that works. Actually, both
$(CXX) $(CXXFLAGS) $*.cc
and
$(CXX) $(CXXFLAGS) $<
work with nmake of MSVC++

Many thanks for the help, W. Bauer
