Like the Turbo C++ IDE, the BGI, Borland Graphics Interface, is old, but it’s not yet outdated. It emulates graphics for the MingW (GCC port) compiler.

WinBGIm is a graphics library ported to computer by Michael Main at the University of Colorado. To setup graphics.h in CodeBlocks, you’ll first have to set up winBGIm library (download graphics.h). There are a few other settings CodeBlocks wants you to make to successfully run or execute C/C++ graphics programs. So, how to include graphics.h in CodeBlocks? If you’ve previously tried downloading graphics.h header file and pasting it in the include folder of your compiler directory, but yet still it showed error, here’s a step-by-step solution to your problem. Why? This is because graphics.h runs only in Turbo C as it is inbuilt there, and is not available in the library folder of CodeBlocks. When you compile such codes in CodeBlocks IDE, it shows error saying “Cannot find graphics.h”. If you know the library’s path (folder), type it in, otherwise do what I do and click the Folder button to browse for the library, as illustrated in Figure 2.You might have come across source codes in C or C++ languages having #include in the program. In Code::Blocks, these options are set in the Linker Settings tab, found in the Compiler Settings dialog box (shown in Figure 1).įor example, to set the location of a library you’ve downloaded, choose either Project, Build Options or you can choose Settings, Compiler. The only complex settings required in Code::Blocks are choosing specific directories for libraries and header files. This choice replaces the -c switch at the command prompt.

To compile a project without linking, choose Build, Compile Current File. This configuration automatically applies the -g switch used at the command prompt. If you plan on debugging your code in Code::Blocks, ensure that the project is created with a debugging build. The settings and dialog box are pretty much identical summon the dialog box by choosing Project, Build Options. Unlike the Compiler Settings dialog box, the Project Build Options dialog box applies only to the current project. Or you can create a new entry on the Compiler Flags sub-tab by right-clicking.Ī similar dialog box is provided for Code::Blocks projects. If you click the Other Compiler Options tab, you can enter switches manually. The Global Compiler Settings screen is chosen, Compiler Settings tab, Compiler Flags sub-tab set as shown in Figure 1. To summon the Compiler Settings dialog box, choose Settings, Compiler in Code::Blocks. Setting compiler options in Code::Blocks (click to embiggen).
