I am trying to write a program in C using Dev-C 5.6.1. I go to compile the program, and nothing happens. It compiles with zero errors, zero warnings, and an output of 0 bytes (it doesn't even create an exe file, nor any of the.o files). Download and install Dev C. Now that you have Dev C installed, run Dev C and select File → New → Source File. (We don't need to create an entire project at this point.) Cut and paste the example code into the window and the select File → Save As. Add the source and header files to the new project using Project Add to Project or the '+' sign in the middle of the top toolbar. Go to Project Project Options (Alt+P) Makefile and tick the 'Use custom makefile' option. Then point Dev-C to the custom makefile below.

-->Visual Studio includes a command-line C and C++ compiler. You can use it to create everything from basic console apps to Universal Windows Platform apps, Desktop apps, device drivers, and .NET components.
In this walkthrough, you create a basic, 'Hello, World'-style C++ program by using a text editor, and then compile it on the command line. If you'd like to try the Visual Studio IDE instead of using the command line, see Walkthrough: Working with Projects and Solutions (C++) or Using the Visual Studio IDE for C++ Desktop Development.
In this walkthrough, you can use your own C++ program instead of typing the one that's shown. Or, you can use a C++ code sample from another help article.
Prerequisites
To complete this walkthrough, you must have installed either Visual Studio and the optional Desktop development with C++ workload, or the command-line Build Tools for Visual Studio.
Visual Studio is an integrated development environment (IDE). It supports a full-featured editor, resource managers, debuggers, and compilers for many languages and platforms. Versions available include the free Visual Studio Community edition, and all can support C and C++ development. For information on how to download and install Visual Studio, see Install C++ support in Visual Studio.
The Build Tools for Visual Studio installs only the command-line compilers, tools, and libraries you need to build C and C++ programs. It's perfect for build labs or classroom exercises and installs relatively quickly. To install only the command-line tools, look for Build Tools for Visual Studio on the Visual Studio Downloads page.
Before you can build a C or C++ program on the command line, verify that the tools are installed, and you can access them from the command line. Visual C++ has complex requirements for the command-line environment to find the tools, headers, and libraries it uses. You can't use Visual C++ in a plain command prompt window without doing some preparation. Fortunately, Visual C++ installs shortcuts for you to launch a developer command prompt that has the environment set up for command line builds. Unfortunately, the names of the developer command prompt shortcuts and where they're located are different in almost every version of Visual C++ and on different versions of Windows. Your first walkthrough task is finding the right one to use.
Note
A developer command prompt shortcut automatically sets the correct paths for the compiler and tools, and for any required headers and libraries. You must set these environment values yourself if you use a regular Command Prompt window. For more information, see Set the Path and Environment Variables for Command-Line Builds. We recommend you use a developer command prompt shortcut instead of building your own.
Open a developer command prompt
- If you have installed Visual Studio 2017 or later on Windows 10, open the Start menu and choose All apps. Scroll down and open the Visual Studio folder (not the Visual Studio application). Choose Developer Command Prompt for VS to open the command prompt window.If you have installed Microsoft Visual C++ Build Tools 2015 on Windows 10, open the Start menu and choose All apps. Scroll down and open the Visual C++ Build Tools folder. Choose Visual C++ 2015 x86 Native Tools Command Prompt to open the command prompt window.You can also use the Windows search function to search for 'developer command prompt' and choose one that matches your installed version of Visual Studio. Use the shortcut to open the command prompt window.
- Next, verify that the Visual C++ developer command prompt is set up correctly. In the command prompt window, enter
cl
and verify that the output looks something like this:There may be differences in the current directory or version numbers. These values depend on the version of Visual C++ and any updates installed. If the above output is similar to what you see, then you're ready to build C or C++ programs at the command line.NoteIf you get an error such as 'cl' is not recognized as an internal or external command, operable program or batch file,' error C1034, or error LNK1104 when you run thecl
command, then either you are not using a developer command prompt, or something is wrong with your installation of Visual C++. You must fix this issue before you can continue.If you can't find the developer command prompt shortcut, or if you get an error message when you entercl
, then your Visual C++ installation may have a problem. Try reinstalling the Visual C++ component in Visual Studio, or reinstall the Microsoft Visual C++ Build Tools. Don't go on to the next section until thecl
command works. For more information about installing and troubleshooting Visual C++, see Install Visual Studio.NoteDepending on the version of Windows on the computer and the system security configuration, you might have to right-click to open the shortcut menu for the developer command prompt shortcut and then choose Run as administrator to successfully build and run the program that you create by following this walkthrough.

Create a Visual C++ source file and compile it on the command line
- In the developer command prompt window, enter
md c:hello
to create a directory, and then entercd c:hello
to change to that directory. This directory is where your source file and the compiled program are created in. - Enter
notepad hello.cpp
in the command prompt window.Choose Yes when Notepad prompts you to create a file. This step opens a blank Notepad window, ready for you to enter your code in a file named hello.cpp. - In Notepad, enter the following lines of code:This code is a simple program that will write one line of text on the screen and then exit. To minimize errors, copy this code and paste it into Notepad.
- Save your work! In Notepad, on the File menu, choose Save.Congratulations, you've created a C++ source file, hello.cpp, that is ready to compile. Download plugsound free vst.
- Switch back to the developer command prompt window. Enter
dir
at the command prompt to list the contents of the c:hello directory. You should see the source file hello.cpp in the directory listing, which looks something like:The dates and other details will differ on your computer. If you don't see your source code file, hello.cpp, make sure you've changed to the c:hello directory you created. In Notepad, make sure that you saved your source file in this directory. Also make sure that you saved the source code with a.cpp
file name extension, not a.txt
extension. - At the developer command prompt, enter
cl /EHsc hello.cpp
to compile your program.The cl.exe compiler generates an .obj file that contains the compiled code, and then runs the linker to create an executable program named hello.exe. This name appears in the lines of output information that the compiler displays. The output of the compiler should look something like:NoteIf you get an error such as 'cl' is not recognized as an internal or external command, operable program or batch file,' error C1034, or error LNK1104, your developer command prompt is not set up correctly. For information on how to fix this issue, go back to the Open a developer command prompt section.NoteIf you get a different compiler or linker error or warning, review your source code to correct any errors, then save it and run the compiler again. For information about specific errors, use the search box on this MSDN page to look for the error number. - To run the hello.exe program, at the command prompt, enter
hello
.The program displays this text and exits:Congratulations, you've compiled and run a C++ program by using the command-line tools.
Next steps
This 'Hello, World' example is about as simple as a C++ program can get. Real world programs usually have header files, more source files, and link to libraries.
You can use the steps in this walkthrough to build your own C++ code instead of typing the sample code shown. These steps also let you build many C++ code sample programs that you find elsewhere. You can put your source code and build your apps in any writeable directory. By default, the Visual Studio IDE creates projects in your user folder, in a sourcerepos subfolder. Older versions may put projects in a *DocumentsVisual Studio <version>Projects folder.
To compile a program that has additional source code files, enter them all on the command line, like:
![How to compile a file in dev c free How to compile a file in dev c free](/uploads/1/2/6/1/126133460/109736731.jpg)
cl /EHsc file1.cpp file2.cpp file3.cpp
The
/EHsc
command-line option instructs the compiler to enable standard C++ exception handling behavior. Without it, thrown exceptions can result in undestroyed objects and resource leaks. For more information, see /EH (Exception Handling Model).When you supply additional source files, the compiler uses the first input file to create the program name. In this case, it outputs a program called file1.exe. To change the name to program1.exe, add an /out linker option:
cl /EHsc file1.cpp file2.cpp file3.cpp /link /out:program1.exe
And to catch more programming mistakes automatically, we recommend you compile by using either the /W3 or /W4 warning level option:
cl /W4 /EHsc file1.cpp file2.cpp file3.cpp /link /out:program1.exe
The compiler, cl.exe, has many more options. You can apply them to build, optimize, debug, and analyze your code. For a quick list, enter
cl /?
at the developer command prompt. You can also compile and link separately and apply linker options in more complex build scenarios. For more information on compiler and linker options and usage, see C/C++ Building Reference.You can use NMAKE and makefiles, MSBuild and project files, or CMake, to configure and build more complex projects on the command line. For more information on using these tools, see NMAKE Reference, MSBuild, and CMake projects in Visual Studio.
The C and C++ languages are similar, but not the same. The MSVC compiler uses a simple rule to determine which language to use when it compiles your code. By default, the MSVC compiler treats files that end in
.c
as C source code, and files that end in .cpp
as C++ source code. To force the compiler to treat all files as C++ independent of file name extension, use the /TP compiler option.The MSVC compiler includes a C Runtime Library (CRT) that conforms to the ISO C99 standard, with minor exceptions. Portable code generally compiles and runs as expected. Certain obsolete library functions, and several POSIX function names, are deprecated by the MSVC compiler. The functions are supported, but the preferred names have changed. For more information, see Security Features in the CRT and Compiler Warning (level 3) C4996.

How to Install Dev-C++ and the GLUT Libraries
for Compiling OpenGL Programs with ANSI C
for Compiling OpenGL Programs with ANSI C
(version of July 16, 2009)
These notes explain how to compile programs written in ANSI C with OpenGL and GLUT using the Dev-C++ compiler.
Bloodshed Dev-C++ is a free C++ compiler and development environment for Windows operating systems. Like most C++ compilers, it also can be used to compile ANSI C. By installing the GLUT header and library files, it can be used to write programs that use OpenGL. This is needed to run programs for Edward Angel's textbook, Interactive Computer Graphics 5th edition and possibly other computer graphics texts.
These notes do not explain how to compile OpenGL with C++ . The 6th edition of Angel's book uses C++ which will not work with these notes.
These instructions have been tested on a small variety of Windows 2000 and Windows XP systems. These systems come with the files needed for OpenGL, but not the files needed for GLUT.
Dev-C++ does not work well with Microsoft's Vista. The problem, and a possible fix, is discussed here: http://aresio.blogspot.com/2007/06/vista-and-dev-cpp.html but I have not tested this information.
I. Download Dev-C++ from http://www.bloodshed.net/dev/devcpp.html and install it.
Details:
Get Dev-C++ 5.0 beta 9.2 (4.9.9.2) (9.0 MB) with Mingw/GCC 3.4.2 Although this is a 'beta' version, it works perfectly fine. Click on SourceForge to go to a list of download sites and pick one. The file will be something like devcpp4.9.9.2_setup.exe. Save this file in a place like C:Temp.
When the download is complete, click on the 'open' button to start the installation process. (Or go to C:Temp andDouble click on devcpp4.9.9.2_setup.exe). You will see a few screens that ask you to pick a language (English) and to agree to the license terms. Choose a 'typical' installation.
Accept the suggested destination for the installation:
Many subdirectories and files are extracted to the destintion:
Answer 'yes' when it asks if you wish to install Dev-cpp for all users. Note: if the installation fails, re-install and try 'no' for this.
A screen says the installation is complete:
Keep the check mark in the box. Click on 'Finish'. A first-time configuration screen appears:
Pick 'English' and 'New Look'. In the next several screens, hit 'Yes' for its suggestions.
Eventually you are done. Click 'OK'.
II. DEV-C++ starts up. Try out the installation with a simple C program.
Details:
The program starts up automatically.
Click File/New/Project. Pick a name for the project (such as 'myProject'). Click 'C Project'. Click on 'Empty Project'. Click 'OK'.
In 'Create New Project', click 'save' (later on you will probably want to create separate subdirectories for your various projects.).
Click 'File/New/Source File' and in 'Add source file to current project' click 'Yes'. You now get a screen where you can edit the source file.
Type in a simple C program, as below. Now click 'File/Save As' and save the file as 'hello.c' (or other name.) Important: be sure that the file extension is .c. With any other extension (such as the suggested .cpp) you will have problems compiling.
Now click 'Execute/Compile and Run'
The program will (hopefully) compile, run, and write its output to a DOS window. If you have the
system('pause')
statement in your program, the output will stay in the window until you hit a key. Another way to run the program (after it has been compiled) is to start a DOS window outside of the Dev-Cpp system, then navigate to the subdirectory that holds your project, and type hello.exe.At this point, the compiler and development environment has been installed. You should find Dev-C++ listed under 'Programs' on the 'Start' menu and will now be able to write, compile, and run C (and C++) programs. You will have include files, libraries, and dll's for OpenGL (and all other standard packages) but not GLUT. GLUT manages the windows and other user interface components needed for OpenGL programming, and needs to be separately installed.
If you do not need GLUT , you can quit now.
III. Download and install GLUT
To run OpenGL with GLUT (which is what the programs in Angel's book use), you need to get three files and place each file in its proper directory. All the files you need (and more) are contained in one zip file.
Details:
Download GLUT files from http://chortle.ccsu.edu/Bloodshed/glutming.zip Download the file
glutming.zip
Save the zip file in some convenient location (perhaps C:temp).Double click on glutming.zip (or otherwise unzip it). You will see the files that are in the zip archive. (Your un-zipping program will probably be diferent than the one shown here, but should work about the same.)
Click on 'Extract' to extract all the subdirectories and files. Pick some convenient directory to extract them to (perhaps C:tempglutming). You only need three files, but extract all of them anyway.
Only three of the files in the various subdirectories are needed. Each of the three files should be put in a subdirectory with other files of its type. Use Explorer to move the files to where they are needed.
Note: If you only see some of these files listed in Explorer, click on 'View/Options/View' and then select the radio button 'Show all Files'.
glut.h -- copy this file to C:Dev-CppincludeGL
Copy from your 'unzipped' subdirectories (wherever they are):
To here:
How To Compile A File In Dev C Mac
libglut32.a -- copy this file from your unzipped directories to C:Dev-Cpplib
There may be a newer version of this file there, already. Replace that version with the one you unzipped (if you keep the newer version your programs will not link correctly.)
Copy from your 'unzipped' subdirectories:
To here:
glut32.dll -- move this file to C:WINNTSystem32, or similar location. How to switch between mac and pc in boot camp.
The location for this file depends on your operating system. The directory where it goes is the directory that holds the dynamic load libraries (*.dll). An easy way to find where it should go is to look for glu32.dll (use 'Search' from the start menu).
The directory to use should also have the files glu32.dll and opengl32.dll. These should have come with your operating system.
IV. Test Dev-cpp with GLUT
The essential step in compiling and running a C program that contains OpenGL and GLUT functions is to tell the linker where the libraries are. This is done by clicking Project/Project Options/Parameters/Add Library or Options and then navigating to the libraries you need to include: libopengl32.a, libglu32.a, and libglut32.a. The libraries should be added in that order.
Details:
a. Create a subdirectory for a project. Do this first, before you start Dev-Cpp. Create a new subdirectory with 'Explorer' by clicking 'File/New/Folder'.
For example, create a folder C:GLproject.
b. Start Dev-cpp:
c. Start a new project by clicking File/New/Project. In the panel that pops up, name the project something like 'rectangle', click on 'empty project' and 'C': Click OK.
Note: For compiling with OpenGL you must create a project. You need to have a project (not just a single C file) in order to link in the OpenGL libraries.
d. In the next panel, navigate to your folder C:GLproject, and click 'Save'.
e. In Dev-C++, click 'File/New/Source File' and then in the next panel 'Add to Project' click 'yes'. Click 'File/Save As' and then give the file a name. Navigate to your project subdirectory to save the file in it. Name the file something like 'rectangle.c'
Be sure that the file names ends with '.c' anything else will cause big problems.
f. Click and drag your mouse over the following program so that it is highlighted, then click 'Edit/Copy' from the browser's menu bar.
g. Now click in the editing window of Dev-cpp and then click 'Edit/Paste' in its menu bar. The program will appear in the editing window.
h. Click 'File/Save'. The file in your project directory should now contain an OpenGL program.
i. Tell Dev-cpp what libraries need to be linked. Click 'Project/Project Options'.
j. Now click 'Parameters'. Click the 'Add Library or Object' button and navigate to the libraries that should be added, found under C:Dev-cpplib
- ./lib/libopengl32.a
- ./lib/libglu32.a
- ./lib/libglut32.a
Add them in that order (only). Notice that the slashes will appear in Unix style '/' rather than DOS-style '.
When you are done adding the three libaries, you should see:
The exact pattern of '././.' you see depends on how deep in the directory structure your source file lies.
Click 'OK'.
k. Click 'Execute/Compile and Run'. The program should compile, link, and run:
If things don't work (very common) click on the 'Compile Log' tab for some confusing error messages. If you see something like the following, it means that you made a mistake in adding the libraries to the project:
Try to fix the list of libraries, or perhaps start over from scratch.
