about makefile and stuff

mentrial · 02-10-2003, 06:48 AM

i'm a real

both with linux and c++ (or any other)

i was trying to make this

#include <iostream.h>

int main()
{
cout << "¡Hola mundo!\n";
return 0;
}

yes, i know it's simple but i can't even do that

i wrote the code in a new file in emacs, and when i try to compile it it say's that i needed a makefile
the book from where i'm learning doesnt say anything about a makefile

if anyone could help my with this i'll by gratefull

well that in itself doesn't need a makefile, you'd use one when distributing an application but just that you'd compile using "gcc code.c -o code" or such like. nothing else would be needed. btw you're using deprecated code now. cout is no longer resident in the default name space. either add a line saying "using namespace std;" before using it, or change "cout" to "std::cout"

ummm thanks, but what's "gcc code.c -o code" keeps telling me that it doesn't found a makefile.
cant i use cout? what's that stuff?

sorry.. can you say that again.... you type "gcc....." in a terminal if that's what you mean.

you can set emacs up to do it, but i don't use emacs so can't help you with that. you could write a makefile for it if you wanted to ... just have a look on google for some beginners guides, you'd only need a line or two.

or u can use "g++ code.c -o code" and run the executable by typing "./code"

If you invoke compile from emacs you'll have to modify the
mini-buffer to say

Code:

gcc code.c -o code

rather than make (or make -k in your case) :)

Alternatively, create a file named Makefile
and do something like that :}

Makefile:

Code:

#Make for code snippet
BASEDIR=${PWD}
CCC=g++
CC=gcc
#directories for include files
INC=-I/usr/lib/qt/include -I/usr/local/include/stlport 
#required libraries
LIBS=-L/usr/lib/qt/lib -lqt-mt -L/usr/local/lib -lstlport_gcc
CFLAGS=-g -DLINUX -DLINUX_GPP -Woverloaded-virtual  ${INC} 

code: code.o
	${CCC} ${CFLAGS} ${LIBS} code.cc  -o code

Edit INC and LIBS (or actually everything) to your hearts content ;)

Cheers,
Tink
