It provides the editor, project tools and controls for calling external compilers, linkers and debuggers. On Windows, the official MinGW setup package includes a compiler toolchain; other packages may not. The latest stable release listed by the project is Code::Blocks 25.03, dated March 31, 2025.
What Code::Blocks does—and what it does not
Code::Blocks gives you a graphical environment to edit code, organize projects, build programs and work with a debugger. The actual compilation and linking are performed by external tools that the IDE invokes. As the Code::Blocks User Manual puts it, “Code::Blocks itself, is NOT a compiler nor a linker, but it creates a graphic interface to these tools (and many others) to help you to build your executables by using external compilers and linkers.”
That distinction matters during setup: installing the IDE alone does not necessarily install a compiler. You need both Code::Blocks and a compatible, configured toolchain to build a program.
What you can use it for
The project describes Code::Blocks as a free, extensible IDE for C, C++ and Fortran. It supports Windows, Linux and Mac, and its plugin-based design lets the environment be extended. The official feature list documents capabilities including:
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Project and workspace management, including multi-target projects and inter-project dependencies.
- A custom build system and parallel builds.
- Editor features such as syntax highlighting, code folding, code completion, a class browser, smart indentation and tabs.
- Debugger interfaces for GNU GDB and Microsoft CDB, with features such as breakpoints, watches, call stack, disassembly and memory inspection.
These are documented features, not a guarantee of identical support for every language, compiler, operating system or release. Fortran is explicitly within the project’s scope, and the feature list includes Fortran code folding; the available information does not establish that every C/C++ assistance feature has equal Fortran support.
Choose the right download and compiler
The official downloads page lists binaries for Windows, Linux and Mac OS X. It says default builds are 64-bit starting with release 20.03, while 32-bit builds remain available. Check the package description for the release you are downloading: installer contents can differ.
Rank #2

| Windows package | What the official page says it includes | What to check |
|---|---|---|
codeblocks-25.03mingw-setup.exe |
Code::Blocks plus GCC, G++, GFortran, Clang and GDB 14.2.0 from WinLibs. | This is the package identified for a bundled compiler toolchain and debugger. Confirm the download page still lists the same contents for your chosen release. |
| Standard setup package | Code::Blocks and plugins; the page does not make the same compiler-bundle claim. | Install a compatible compiler separately if needed, then configure it in the IDE. |
| Non-admin or no-setup variants | Variants are listed on the downloads page. | Review each package’s description; do not assume it contains a compiler. |
The listed Windows MinGW bundle provides GCC/G++ for C and C++, and GFortran for Fortran. If you use a package without a compiler, install a compatible toolchain for your system and point Code::Blocks to it. Compiler choices documented by the project include GCC (including MinGW), MSVC++, Clang, Digital Mars, Borland C++ 5.5 and Open Watcom; support listings describe integrations, not compilers included with every download.
On Linux, a compiler may already be installed, but this depends on the distribution and what was installed. Check for a working compiler rather than assuming Code::Blocks or the operating system supplied one.

Create a C or C++ project
The project wizard sets up a starter project and asks you to choose a language, compiler and build targets. Code::Blocks stores project sources and build settings in a .cbp project file, according to the manual.
- Open File → New → Project.
- Choose a project wizard, such as Console application, and select the language.
- Enter a project name and destination folder.
- Choose the compiler and the Debug and/or Release build targets offered by the wizard.
- Finish the wizard, then add source files from the project-management context menu if needed.
- Build and run the project using the IDE’s build controls.
A successful build depends on the selected compiler being installed and correctly configured, as well as the project’s language and build settings being appropriate for the source files.

Using Code::Blocks for Fortran
Fortran is an explicitly supported use case in the project’s overview and manual. The Windows MinGW setup package listed above includes GFortran. For other operating systems or packages, ensure a Fortran compiler is installed and configured before building. The project’s feature documentation confirms Fortran code folding, but does not establish feature parity with C and C++ for completion, debugging or project templates.

- Confirm that the compiler is installed. If you chose a Windows package without the MinGW bundle, install a compatible compiler separately.
- In Code::Blocks, inspect the selected compiler and its installation path; make sure it points to the toolchain you installed.
- Check that the project language and build settings match your source files, and that the intended Debug or Release target is selected.
- Build again. If the error remains, use the compiler’s reported message to distinguish a missing toolchain or path from a source-code error.
