CodeBlocks preprocessor file

This is a discussion on CodeBlocks preprocessor file within the C++ Programming forums, part of the General Programming Boards category; Sorry to 'bump' a somewhat oldish topic but I'm getting back onto the command line stuff again in this sites ...

    Sorry to 'bump' a somewhat oldish topic but I'm getting back onto the command line stuff again in this sites tutorials..

    I figured that I can browse to the path of my .exe (that I compiled in codeblocks) in the cmd line and run it from there by typing the name and specifying parameters.

    I cannot figure out how to specify these parameters within the codeblocks IDE, is this even possible?

    Is there built in commands for preprocssing, compiling and such within ms DOS without the need for downloading anything?

    If so where can I find documentation on this?

    With regard to the g++ compiler I tried to download it but it took 6 hours only to fail at the very end. I had a choice of mirrors does anyone know of a faster way to download it?

    I think the command-line parameter choice thingy only appears if you have specified a project (as opposed to just compiling a single file).

    There is no native compiler to MS-DOS. (To the best of my knowledge, there's no "native" compiler in any operating system although my understanding is a lot of linux distributions these days come with gcc already installed by default.)

    If you have Code::Blocks then you should have the MinGW C++ compiler (called g++, with an option for some outrageous name like mingw-c++.exe) already there.

    Look for Set programs' arguments... under Project

    No - you need a compiler. Once you have that, a single command will take care of preprocessing, compiling and linking.

    You should have gotten that along with CodeBlocks. If you didn't, you downloaded the wrong package. You want the one called codeblocks-10.05mingw-setup.exe. Here:

    Sorry this compiling stuff really threw me from the beginning. Yes I have the 10.05mingw package.

    I just noticed a setup file in the mingw folder... tdm-mingw-1.908.0-4.4.1-2.exe

    Do i have to run this or is g++ already installed? I see no g++ reference anywhere, heck I don't even know what it is I'm just trying to go through tutorials and if I don't want to skip over something just because I don't fully understand it.

    I browsed the codeblocks docs but I got reminded of using gamemaker: unless I know exactly what I'm looking for and know exactly why I am using it, its all nonsense.

    Whats the difference between compilers? I thought codeblocks was a compiler and g++ was something entirely different, as would be the ms visual studio.

    The language itself is hard enough.

    Codeblocks is not a compiler. Codeblocks is an "integrated development environment", that is, an editor that does syntax highlighting and has a button you can push that will run a compiler.

    This is complicated but the learning of the language and an application that can faciliate the learning are so intertwined that this is hard to avoid.

    So codeblocks uses g++? What different compilers are there?

    In my programming experience(albeit there little of) I have always been fascinated with the lowest level stuff, all the way down to the circuit boards. I have to learn somewhere so I'm digging around with what I can find/do.

    If I want to run a simple piece of code I would rather do it in the command line than an entire IDE, so I guess I am looking for the 'bare bones' as I am going. Obviously I don't want to do everything from scratch but I atleast want to know/need to know what is going on.

    I'm going to be lazy and let someone else do the listing.

    Actually CodeBlocks is an IDE ... with the right settings it can work with any compiler...

    What different compilers are there...

    List of compilers - Wikipedia, the free encyclopedia

    If you're looking for downloadable stuff...

    Free Compilers and Interpreters for Programming Languages (thefreecountry.com)

    Well that's good, and we should all know how... but if you ever get into a real project; several EXEs and DLLs, settings, dialogs, etc... you will very quickly yearn for the organizational tools a good programmer's IDE provides...

    You shouldn't have to run that unless you de-selected it in the wizard when you installed CodeBlocks. It's included in the standard install.

    Look in C:\Program Files\CodeBlocks. You should see a folder called MinGW -- that's the GCC compiler directory. It contains the C compiler (gcc) and the C++ compiler (g++). In the MinGW directory you will find bin, include and lib directories. Since you want to compile from the command line it will be convenient to add those to your user path, include and lib environment variables. If you don't know how to do that, ask.

    If the compiler isn't already installed, you can either try running that mingw setup file, or uninstall and reinstall CodeBlocks (this time making sure that MinGW is selected in the wizard). Given your inexperience, reinstalling might be the better alternative to be sure it ends up configured correctly.

    IMHO, you don't need to waste time investigating other compilers at this time. Unless you have a compelling need to use another compiler GCC is your best choice for a free, modern, standards-compliant compiler.
