As people have said, check the path. Don't start copying the cygwin DLLs around - that is not necessary, may cauxse problems later and won't solve the problem. And when it comes to setting the Windows PATH variable and others I've found this small program to be quite useful and better than squinting at the MS control panel aplet.
I am assuming you are using the Windows Shell here. If you invoke the compiler from a cygwin Bash shell, all the paths should be set for you.
I am trying to execute my first "Hello World! I have written a small hello-world program, and saved it in hello. From the command prompt I write:. Something with my installation or my paths seems to be not Ok, but I cannot figure what.
I have run the exe file of cygwin, and in the installation directory I have got all necessary files, I think: bin folder, lib, Cygwin. I have read that in case of such error message I should check whether the cygwin1. I have looked there, and I don't have such a file there. I have cygwin1. I think that the hello-world program shouldn't contain any syntax errors, I have just copied it.
Also, when I write. I get the same error message: that the command is not recognized. I would appreciate if someone give me a hint what should I look at. Thank you. I don't know how important this is, but I receive an error message when I try to compile the program in the DOS command prompt:.
Solution 4 I am assuming you are using the Windows Shell here. View more solutions. Author by user Updated on July 09, How do I copy the result from the shell? It is very long, and I suppose there should be a way, but I simply can't copy anything from the shell. If there is no way, I will try to write it here it is 10 lines. RobS almost 14 years.

1. Installing a C++ compiler, debugger, and make for Windows XP - Your Answer
Once you have a compiler, you will also want to consider what kind of development environment you want to employ when writing your programs. The CygWin compiler itself takes about 60Meg of disk storage. In fact, you're really getting a pretty comprehensive Unix emulation package.
Depending upon what you opt for in the way of a development environment, you may need anywhere from 2 to 30Meg additional space for the development environment. It can be anywhere. Cygwin creates one by default inside its own installation area, but I like to keep it in a separate directory so if you have to uninstall or reinstall CygWin, you don't risk losing your personal data files.
Just save it under any name that the browser will permit e. Repeat as necessary with the other two files. Poke around their site a bit, just to get familiar with it. You may need to go back there if you have questions. When you're ready to install, click on their "Install Cygwin Now" link to run their setup. Follow the instructions provided by the CygWin setup program. Basically, you answer the usual kinds of installation questions about where you want to put it, choose a nearby site from which to download the bulk of the package, and then sit back.
The installation takes place in two steps. First, the files are downloaded onto your disk, then they are installed. Set up an empty directory folder anywhere on your hard drive for this. Once you have successfully installed the compiler, you can delete this directory to save space. You can select which packages you want to download and install.
You can always come back later and run the setup program again to install additional packages, remove ones you have decided you don't want anymore, or to check for updates to the ones you have already installed. Click on the circular arrows besides each of the following until a version number is displayed: gcc, gdb, make. When you select these, you will find that certain other packages get selected automatically as well. That's because the items you chose require those others in order to run properly.
These will add up to about 60Meg of disk space. In addition, some packages that you might want to add to your minimal install include:. I generally create a shortcut icon on my desktop with target. Support for making secure, encrypted connections to other machines over a network. A variant of the emacs text editor - this runs as a native Windows application or as an X window application. If you get this, also get Editors:xemacs-sumo.
A reasonable text editor. See my comments in Section 4. If you don't use emacs or vim, then get this lightwweight editor because you will want some kind of Unix editor.
If you get this, get Net:openssh as well. OK, time to test the basic compiler installation. You should have a command window now, running bash. Different disk drives can usually, but not always, still be accessed by putting the letter in front of a color, e. Try using ls and cd to move around, looking at your drives. When you're comfortable with that, cd to a directory where you can work. Use your favorite editor to create a file hello. This should compile the program. Use ls and you should find that an executable, hello.
If all has gone well, you now have a working compiler. Unix allows a system administrator to make directories appear to be in more than one place at a time. We'll use the same technique to set up a more convenient name for the drives on your PC. Now try. Do the same for any other hard drives on your machine. You may also want to mount drives for your floppy or CD reader as well. The simplest case for each compiler involves compiling a single-file program or a program with one.
For example, use an editor to prepare the following files:. The compiler generates an executable program called a. If you don't like that name, you can use the mv command to rename it.
Alternatively, use a -o option to specify the name you would like for the compiled program:. As you progress in your study of programming, you will discover that programs that can or should be written in a single source code file become increasingly rare. In fact, the earliest stage of compilation, the preprocessor , actually replaces each include by the full contents of the included file. A typical program will consist of many.
Splitting the program into pieces like this helps, among other things, divide the responsibility for who can change what and reduces the amount of compilation that must take place after a change to a function body.
When you have a program consisting of multiple files to be compiled separately, add a -c option to each compilation. This will cause the compiler to generate a. Then invoke the compiler on all the. If there are no other. The same procedure works for the gcc compiler as well. Actually, you don't have to type separate compilation commands for each file. You can do the whole thing in one step:. But the step-by-step procedure is a good habit to get into.
As you begin debugging your code, you are likely to make changes to only one file at a time. If, for example, you find and fix a bug in file2. An even better way to manage multiple source files is to use the make command. Another useful option in these compilers is -D.
This can be useful as a way of customizing programs without editing them. This is useful in conjunction with compiler directive ifdef , which causes certain code to be compiled only if a particular name is defined.
For example, many programmers will insert debugging output into their code this way:. Follow the links to learn more about the GCC 4.
