Also you can use MinGW, which lets you install a gcc for windows.

Unfortunately, there is no in-built compiler. You need to install one. That's the MSVC compiler, not a different one. Show 10 more comments. Active Oldest Votes.

If instead of installing just GCC you install the entire MSYS2 toolkit, you'll get the commandline tools linked to a package repository that works just as well as the linux distributions.

I was known of using MingW before. Skip To Main Content. Safari Chrome Edge Firefox. The compiler provides a shortcut to access the command line with the appropriate environment variables already set.

To invoke the compiler from the command line: Open the Windows Start. You can see the executable program name, simple. If you get an error such as 'cl' is not recognized as an internal or external command, operable program or batch file,' error C, or error LNK, 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.

If 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 at the top of this page to look for the error number. This 'Hello, World' example is about as simple as a C program can get. Real world programs have header files and more source files, link in libraries, and do useful work.

You can use the steps in this walkthrough to build your own C code instead of typing the sample code shown. You can also build many C code sample programs that you find elsewhere.

To compile a program that has additional source code files, enter them all on the command line, like:. The compiler outputs a program called file1. To change the name to program1. The compiler, cl. You can also compile and link separately and apply linker options in more complex build scenarios. By default, the MSVC compiler treats all files that end in. The cl. This name appears in the lines of output information that the compiler displays.

The output of the compiler should look something like:. If you get an error such as 'cl' is not recognized as an internal or external command, operable program or batch file,' error C, or error LNK, 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. If 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. Real world programs usually have header files, more source files, and link to libraries.

You can put your source code and build your apps in any writeable directory. To compile a program that has additional source code files, enter them all on the command line, like:. Without it, thrown exceptions can result in undestroyed objects and resource leaks. 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. To change the name to program1.

The compiler, cl. You can apply them to build, optimize, debug, and analyze your code.
