问题
I want to have a deeper understanding of how C programmes are run.
But IDEs stops us from doing that.
So is it possible that I manually set up the environment and write code in text editors, and finally run it in a prompt?
If the answer is yes, how?
回答1:
As others have said, install MinGW (I'm assuming you are using Windows) and put its bin directory on your path. Open a command line windows, and create a file with a text editor, such as notepad - call it foo.c:
#include <stdio.h>
int main() {
printf( "hello world\n" );
return 0;
}
Then, use the gcc compiler to compile it, creating an executable called foo.exe:
> gcc foo.c -o foo.exe
lastly, run foo.exe from the command line:
> foo.exe
hello world

I don't see why an IDE should prevent understanding how a C program works. An IDE usually abstracts the building process, i.e. it creates build rules for you, runs the program and the debugger. This does not have any effect on the way the program itself works, it's just more "user friendly" (depending on how you define "user friendly").
You can always build programs without the help of an IDE. You can even use Microsofts Visual Studio from the command line, and you won't see the GUI at all. Similar for XCode on Mac OS X.
If you want to build a program without using any IDE, you basically write the source code the same way you do with IDE. You can even use the IDE as editor. Afterwards, you need to compile your program. IDEs usually have functionality that makes writing the source code easier like automatic completion of structure elements, basic syntax checking and the like. If the program consists of only one single source file this is usually rather trivial. If you have more than one source file (which should be true for almost everything other than the usual "Hello World" example) you can still do that manually. However, this is a tedious and error prone process. In the Unix world, make is the tool of choice to automate this. You can use MinGW to get such an environment on Windows. Cygwin is another alternative here. You could, however, also use nmake out of MSVC and write the input for that manually (never did that myself) -- it's basically the same a Makefile is for make.
Creating a Makefile can be non-trivial. There are several generators to make that easier. That's basically the same IDEs do by abstracting the build process. Examples for Makefile generators are the autotools (sometimes also known as "GNU build system") and cmake.
Building programs from the command line also does not have any effect about the program having a GUI or not. You can (assuming Windows again) run any .exe file from the command line. If it's a GUI application the GUI will show up, if it's a console application it will run in the console window.

Download Cygwin and make sure to install GCC, the GNU C compiler.
You can write your C programs in a text editor, compile them with GCC, and then execute them.
回答4:
Of course! There are a bunch of C compilers available for Windows, a few one to get you going:
- Visual Studio has an express edition which is free and comes with a compiler
- MinGW is the Gnu C Compiler ready-to-run for windows
- There are plenty of others, but the ones above should be .. enough for now
As for a text editor, you might want to choose one that comes with C-syntax highlighting, like vi, Emacs or some other text editor. Mastering an editor is by the way really useful, regardless of what your language is.
回答5:
I don't know what you mean. You want to write C programs in a text editor an then, compile?? Ofcourse, you CAN do that:
1- Write a C code
2- Get a compiler such as gcc (there is a windows version)
3- Compile it
4- Run it from console
But, I am not sure if that is what you want to know.
回答6:
You can compile programs for Windows (if that's what he meant) from the command line using all the available tools in the Windows SDK (formerly called the Platform SDK, I believe) which is free to download from Microsoft. I think it has all the same tools Visual Studio has if not most of them.
回答7:
Of course. You'll need something like MinGW compilers set to compile your application (or you could use the IDE-provided compiler). Then just use CMD and execute appropriate compile commands.
Actually, every IDE provides just more easier way to do the same compilation.
回答8:
If you're interested in how large projects are organised, you could try downloading the source code for something like Apache httpd or PHP. These are both in C. On Linux/Mac you can compile them from the command-line using a few simple commands (see the documentation).
回答9:
If you want to see how the build works, most if not all IDE's create a build log which shows the actual command lines issued to invoke the compiler/linker etc. Nothing prevents you from issuing these commands directly on the command line.
What an IDE typically also does for you is dependency management; this is difficult to maintain manually, and best left to the IDE for large projects.
You do not need to download and install any specific compiler or toolchain as some have suggested; the one you have with your current IDE will be sufficient. For example if you have VC++2008 (or 2008 Express), the command line tools are described here.

Here is some simple step that would make you to compile and run c program without IDE
1 - install the TCC (Turbo C compiler)
2- open Notepad and write C code
3 - save as a.c in C:\TC\BIN
4 - then open CMD
5 - compile c code by "tcc a.c"
6 - finally run "a.exe"
回答11:
You just need to install the MinGW compiler and set path to the gcc executable and you're ready to go. Then you can write C code in editor and compile it in command line just like you would on Linux.
