Modifying Your makefile

If you use makefiles to build your Microsoft* application, you need to change the value for the compiler variable to use the Intel® C++ Compiler. You may also want to review the options specified by
CPPFLAGS
. A simple example follows:
Microsoft* makefile Example
# name of the program PROGRAM = area.exe # names of source files CPPSOURCES = area_main.cpp area_functions.cpp # names of object files CPPOBJECTS = area_main.obj area_functions.obj # Microsoft Compiler options CPPFLAGS = /RTC1 /EHsc # Use the Microsoft C++ Compiler CPP = cl # link objects $(PROGRAM): $(CPPOBJECTS)      link.exe /out:$@ $(CPPOBJECTS) # build objects area_main.obj: area_main.cpp area_headers.h area_functions.obj: area_functions.cpp area_headers.h # clean clean: del $(CPPOBJECTS) $(PROGRAM)

Modified makefile for the Intel® C++ Compiler

Before you can run
nmake
with the Intel® C++ Compiler, you need to set the proper environment. In this example, only the name of the compiler changed:
Example
# name of the program PROGRAM = area.exe # names of source files CPPSOURCES = area_main.cpp area_functions.cpp # names of object files CPPOBJECTS = area_main.obj area_functions.obj # # Intel(R) C++ Compiler options CPPFLAGS = /RTC1 /EHsc # Use the Intel(R) C++ Compiler CPP = icl # link objects $(PROGRAM): $(CPPOBJECTS)      link.exe /out:$@ $(CPPOBJECTS) # build objects area_main.obj: area_main.cpp area_headers.h area_functions.obj: area_functions.cpp area_headers.h # clean clean: del $(CPPOBJECTS) $(PROGRAM)
With the modified makefile, the output of
nmake
is similar to the following:

Using IPO in makefiles

By default, IPO generates "dummy" object files containing in
