This is probably a really stupid thing to ask considering the development I'm doing (effectivly creating a virus scanner), but how do I link classes/cpp files?
I have 3 applications/sections that I can compile/combine with a makefile, that's fine, but I need them to run 1, 2, 3 once the output from the makefile is done.
Currently the only section to actually run is whichever I have "main" in and obviously if I put that into all three, they won't compile as one.
I've been looking all over the place at all sorts, header files and such, but there is no mention of how to actually do this although I'm sure it must be possible. I'm used to being able to do this in Java and I'm sure I've seen C++ applications do it, but not worked out how.
I have 3x .cpp files which are combined into one using a makefile:
# Virus Scanner scanner.out : ProgramList.o MD5Hash.o HazardCheck.o g++ -o scanner.out ProgramList.o MD5Hash.o HazardCheck.o /usr/lib/libstdc++.so.5 CONFIG/rudeconfig.lib HASH/src/libhl++.a ProgramList.o: PROGRAMS/ProgramList.cpp g++ -c PROGRAMS/ProgramList.cpp MD5Hash.o: HASH/MD5Hash.cpp g++ -c HASH/MD5Hash.cpp HazardCheck.o: CONFIG/HazardCheck.cpp CONFIG/hazard.conf g++ -c CONFIG/HazardCheck.cpp clean: rm *.o scanner.out #END OF MAKE FILE
scanner.out will run, but only whichever .cpp has "main()" in it, so the other two are defunct but are included within scanner.out. If I compile the three files separately I end up with three programs, but I need them to work together as a single application.
I'm doing all my work on Linux using vi to edit the files, but I assume what I want to do is generic between systems.
Any/All help is appreciated.
