compile program?

Goosie · 06-22-2005, 12:12 PM

Ok, 1 question (this one is more from my lazyness...), im on a linux computer and whenever i want to compile a program i have to type:
c++ (program name.cpp) -o (program name) -Wall -O2
just to compile it and wanted to know if there was a program that cam automatically make it so when i type something like:
compile (program.cpp)
it automatically adds in the extra info? i know it can be coded in c++ but i dont know how to do that yet and wanted to know if there was one already written?

echo "c++ (program name.cpp) -o (program name) -Wall -O2" > batch.sh
chmod 700 batch.sh
./batch.sh

Or learn to make 'make' files.

You could always download the latest version of Dev-C++. It's an Integrated Development Environment (IDE), which is a fancy way of saying you don't need to use command line statements, do your own linking, etc. You just select the type of project you want to work on, write your code in the text editor, click the compile button, and if you don't get any errors, click the execute button and see if you get the desired behavior or a run time error. Works smooth as silk (well, most of the time anyway).

Oh, and did I mention; it's free.

I was thinking about using an IDE but i was told by a ton of people that it does some of the work for you other than compile, and makes you not do some of the work... I wanted to make sure that I actualy know how to do everything that my program is doing... its OK, i guess it isnt that bad to type that to compile a program...

What are you learning by typing that every time?

Do you feel that using a card punch machine to make a stack of 1,000 punch cards representing your program, which you leave in the inbox at your computer center overnight, and then return the next day or maybe the day after that to get the results produced by your program when after the computer operator fed your punch cards into the computer would also teach you something?

nothing, but they said that the IDE's will add stuff to the program that I didnt put there. and by it doing that it might add something and I dont know how to do...

I click on a compile button and a run button everytime I execute a C++ program, and yet I have still been able learn about pointers, classes, inheritance, and polymorphism.

Don't tell anyone, but I also use the following template for every program so I don't have to type it every time:

Code:

#include <iostream>
using namespace std;

int main()
{

     return 0;
}

UFO's do land on earth everyday! they stole my uncle...

well, i guess i might go and try one out

Dev-C++ is great, and like most IDE's, there's also Compile+Run buttons. As long as your program won't cause any compile time errors, click one buttons, it compiles and right after is automatically executed. I've always used IDE's never bothered with that command line compiling.

you're in luck. I made a great makefile that compiles all source files it can find and link then in a final application. Currently it only works for *.cpp file.. I stil haven't added suport to mix *.c files...
here it is

Code:

DIRS := ./ src/
OBJDIR := obj/
EXE  = app

#all .cpp/.c
SRC := $(filter %.cpp, $(foreach DIR,$(DIRS),$(wildcard $(DIR)*.cpp) ))
#all headers with matching .cpp/.c
HDR := $(filter	$(foreach DIR, $(DIRS),$(wildcard $(DIR)*.h)),$(patsubst %.cpp,%.h,$(SRC)))
#all .o from a .cpp/.c
OBJ := $(foreach FOBJ,$(filter %.o, $(patsubst %.cpp,%.o,$(SRC))),$(OBJDIR)$(FOBJ) )
#all .h with matching .o
HOBJ := $(foreach FOBJ,$(filter %.o, $(patsubst %.h,%.o,$(HDR)) ),$(OBJDIR)$(FOBJ) )
#all .o without matching .h 
COBJ := $(filter-out $(HOBJ),$(OBJ))

FLAGS = -Wall

$(EXE): $(OBJ)
	$(CXX) $(FLAGS) $(OBJ) -o $(EXE)

$(HOBJ): $(OBJDIR)%.o: %.cpp %.h
	-@mkdir -p $(OBJDIR)$(dir $(filter %.cpp, $^))
	@touch -a $@
	$(CXX) $(FLAGS) -c $(filter %.cpp, $^) -o $@

$(COBJ): $(OBJDIR)%.o: %.cpp
	-@mkdir -p $(OBJDIR)$(dir $<)
	@touch -a $@
	-$(CXX) $(FLAGS) -c $< -o $@

#clean
.PHONY : c clean
c clean: 
	@echo cleaning temporaries
	-@rm -f $(EXE) $(OBJ) $(foreach DIR,$(DIRS),$(DIR)*.bak "$(DIR)*.*~" )
	-@rmdir -p --ignore-fail-on-non-empty $(filter-out $(OBJDIR)./,$(foreach DIR,$(DIRS),$(OBJDIR)$(DIR) ))

just save this file as 'makefile' and place it in you source directory.
To compile just write 'make' at the commad prompt.
Add/remove directories to the DIRS variable to mntion where your code is
Change EXE variable to your liking. That's the exeutable final name
