Notes For CodeBlocks 13.12 For Windows (Jan 2014) Goto "Settings" menu ⇒ "Debugger." ⇒ Expand "GDB/CDB debugger" ⇒ Select "Default" ⇒ In "Executable path", provide the full-path name of " gdb.exe", for example, " c:\Program Files\codeblocks\MinGW\bin\gdb.exe". It shall be set to the "MinGW" sub-directory of the CodeBlocks installation directory, for example, suppose that CodeBlocks is installed in " c:\Program Files\codeblocks", set it to " c:\Program Files\codeblocks\MinGW". Verify the Compiler's and Debugger's Path: (For CodeBlocks 13.12 For Windows) Goto "Settings" menu ⇒ "Compiler." ⇒ In "Selected Compiler", choose "GNU GCC Compiler" ⇒ Select tab "Toolchain Executables" ⇒ Check the "Compiler's Installation Directory".

Download the installer with GCC Compiler, e.g., (98 MB) (which includes MinGW's GNU GCC compiler and GNU GDB debugger). Select your operating platform (e.g., Windows 2000/XP/Vista/7).

CodeBlocks is surprisingly versatile, and in my opinion, much better than the Visual Studio suite. It supports interactive debugging (via GNU GDB or MS CDB). It supports many compilers, such as GNU GCC (MinGW and Cygwin) and MS Visual C++.

Major point of my posts is to aid in the learning process.CodeBlocks is an open-source, cross-platform (Windows, Linux, MacOS), and free C/C++ IDE.

I may also give inefficient code or introduce some problems to discourage copy/paste coding. They are meant to just illustrate a point. Any samples given are not meant to have error checking or show best practices. So if you haven't already, try explicitly setting your application to use stdcall for WinMain and set the function to extern "C" and see if this builds. If the inverse is true and you have a calling convention other than cdecl as the default, then the compiler will look out for main and silently change the calling convention to cdecl. Int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
Then VC will silently switch it to the correct calling convention and name mangling type. The function as int WinMain(HINSTANCE, HINSTANCE, LPSTR, int) So if you have the default calling convention as cdecl and c++ name mangling and define VC treats main, wmain, WinMain and wWinMain as special, it explicitly looks out for these and makes sure that they are built with the correct calling convention. It is also looking for a C name mangling instead of C++. The WinMain function must be compiled using the stdcall calling convention, but if you look at tutorials and such a lot of them don't include the calling convention, and they still build. I remember gcc being more picky about the definition of WinMain compared to VC. YouĬan always follow a different path later, when your knowledge and skills have improved. While such tools can be used to develop Windows applications I believe that, for a beginner, using Visual Studio and its IDE is a better path to follow. The complexity of properly installing and configuring non-Microsoft development tools. Using Visual Studio also provides the added benefit of simplifying the learning process by removing This will provide many advantages, including helpful tips while coding from IntelliSense. Work from within the IDE instead of using the command line. It also contains many helpful project templates that simplify the process ofĬreating a new application as illustrated in the images that Sam has posted. It is a fully featured environment for coding, buildingĪnd debugging Windows applications and is integrated with the Windows SDK (Software Development Kit) which contains many necessary headers, libraries and helpful tools. I also recommend that you install Visual Studio 2017 Community ( ) and use the Visual Studio IDE during the learning process. Parameter list for the _stdcall convention. The following WinMain is the number of bytes in the function's I suggest you read the documentation in the links provided in his post. Help me!Īs Sam Hobbs has indicated in the above post WinMain is the entry pont for a Windows application. Searched all over the internet but didn't find an apt answer. Undefined reference to don't know what it is or how to resolve it.
But when I copied the very first empty window program from module 1 of the documentationĪnd built it in vs code using the command gcc filename.h it showed an error of To learn a bit more effectively, I decided to copy and build the program and then understand it well. I started learning the windows API for c to build GUI for windows.
