If you have additional include files, -I flag can be used to specify the include directory containing. The command will compile each C++ source file and create object files. Usual compilation with g++ will involve a command as follows. This article explains how you can set up your own makefile for your C / C++ project. G77 -lc -o fprogram fprogram.o ffunction.o cppfunction2.o Informationįor more information, see this make tutorial from the University of Hawaii.Makefiles provide a way to organize build steps involved in C / C++ project compilation. No other files should be touch fprogram.f make `fprogram' is up to we make changes to the source code in fprogram.f andĬppfunction2.C, make should automatically recompile the affected object files, and relink the final executable.

G77 -lc -o fprogram fprogram.o ffunction.o cppfunction2.o we make no changes to any of the files and rerun make, This first time through, none of the object files exist at all, and so all the source code files are make Similarly, any object files newer than the final executable will cause the executable to be relinked. Example Compilation with Above MakefileĮach time we run make, any source code files newer than their corresponding object files will be recompiled. Also ensure that there is an extra blank line at the end of the Makefile. Make absolutely certain you prefix each command line (the gcc, g77, or similar lines) with a TAB character, not spaces. In this case, C, C++, and FORTRAN source code is compiled into object files. SUFFIXES: line gives a list of file extensions that will be used in the final compilation. OBJECTS=fprogram.o ffunction.o cppfunction2.o cfunction2.o The following lines are entered into a normal Example Makefile to Build Mixed FORTRAN, C, and C++ program
