How to Install CodeBlocks IDE on Windows 11 with Compilers ( GCC , G++)

How to use C11 standard in Code::Blocks

I am struggling to make


compatible with


. Despite my efforts, I am unable to find a solution to this problem.

I visited


, proceeded to

compiler settings

and then

Other options

. Despite adding


and trying with


, neither of them appeared to be effective.

After compiling


, I switched to a different compiler (not gcc-4.9), but unfortunately, it did not yield any outcome.

Upon attempting to compile the program that follows:


int main(void){ int arr[] = {0,1,2,3,4}; for(int i=0;i<5;i++){ printf(“%d “,arr[i]); } return 0; }

I get the following:

|6|error: ‘for’ loop initial declarations are only allowed in C99 or C11 mode|

However, executing the task in the terminal (specifically on Ubuntu 15.04, 64-bit) is an alternative option.

./install/gcc-5.2.0/bin/gcc5.2 program.c -o program

Seems to work fine.

I am wondering how to get




to function together.

Solution 1:

As the GCC 5.x versions operate with


as their default setting, it is likely that Code::Blocks is utilizing a method (such as providing




to the compiler) to achieve a distinct outcome.

Examine the various choices submitted to the compiler and discover a method to view the precise command used by Code::Blocks during compilation. Afterward, determine the means to rectify the issue.

Options that are used are:

-Wall -Wextra -Werror -Wstrict-prototypes -Wconversion -std=gnu11 \ -O0 -g -ansi `pkg-config --cflags gtk+-3.0`



is causing harm and can be compared to




. It directly reverses the effects of





Solution 2:

Codeblocks 13.12 for Windows is equipped with an outdated GCC version (4.7.1) which is incompatible with C11.

  • Obtain the most recent version of the Mingw 64 compiler through manual download, as it is unlikely that Mingw32 is updated to incorporate GCC versions from C11.
  • Upon installation, the software will be stored in a relatively unknown directory, such as

    \ \ \ \ \ \ C:\Program\ Files\mingw\-w64\x86_64\-4\.9\.1\-win32\-seh\-rt_v3\-rev1\mingw64\ \ \ \ \

  • To include the path mentioned above in Codeblocks, navigate to Settings, then Compiler, and finally Toolchain executables. Here, you can find the Compiler’s installation directory. Simply press the “auto detect” button.
  • Verify that the C compiler in the current tab is


    , taking into consideration that there may be several installations of GCC on your system. Additionally, ensure that the make program is


  • To create a new flag in the Compiler settings tab, right-click on the list of
    Compiler Flags
    and choose “New flag.” Enter “C11” for the name and


    for compiler flags . Confirm the changes by clicking OK and verify the presence of the newly created C11 option.
  • In order to ensure adherence to C11 standards, both the option ” treat errors ” (which addresses warnings required by ISO C) and the option “-Wall” (which enables all common compiler warnings) should be checked.

Solution 3:

Though I am new to this, I hope my input can be of assistance even though the discussion is dated.

The code shown in the image is an instance of forc99.c, which is featured in C Primer Plus and labeled as example 12.2.

I created new flag

Navigate to the Settings and select the Compiler option. Then, right-click on “general” and choose the “New Flag” option. Enter the necessary details as shown in the image and click on “Ok”. Finally, make sure to check the box of the newly created flag to ensure it has been successfully added. This method has proven to be effective.

The image displays an option for c99 support named -std=c99, located just above the option the speaker created. This option can be used instead.

For code::blocks 16.01 mingw 32bit, I use 4.9.2 as the MSDT.

Solution 4:

Access the “Compiler Flags” tab under “Settings” and select “General”. Then mark the checkbox beside “Follow the C++11 ISO with g++” before clicking “Done”.

Updated 3rd party libs

  • move astyle (plugin) out of beta into v3.0 release
  • updated exchndl (crash handler) to v0.8.2
  • updated exception handler to v0.8.1
  • updated wxPDFDoc library to recent GIT version to resolve licensing issues
  • updated exchndl (crash handler) DLL to v0.8.0
  • updated library to v0.9.5 for better wx30 compatibility

Need to enable C++11 in Codeblocks

In Codeblocks 16, I must activate C++11.

Numerous guides suggest that one can simply opt for the “Have g++ follow the C++11 ISO C++ language standard


feature located in “Settings > Compiler… > Compiler Settings > Compiler Flags”. Nevertheless, I cannot locate this option within my Compiler Flags.

Some propose inserting


in the “Other compiler options” field. However, this method fails to build the code and generates an error message in the “Build Messages” section.

On my Windows 7 system, I am utilizing the Codeblocks 16 IDE, which includes the GNU GCC Compiler.

Solution 1:

Instead of solely relying on the -std=**** option, an alternative approach to rectify the problem (which is clearly caused by the compiler and not Code::Blocks) is to install a newer version of mingw.

Solution 2:

The expected appearance of Code::Blocks 16.1 is with the latest version of GCC (TDM-GCC 4.9.2) included.

To determine your GCC version, utilize the following command.

gcc --version

The MinGW compiler, gcc.exe, can be found in the directory ./CodeBlocks/MinGW/bin.

Ensure that the file you download from CodeBlock’s website is codeblocks-16.01mingw-setup.exe.

Solution 3:

The problem lies in your compiler. To resolve it, you may opt to download the most up-to-date version of MinGW.

After the download is complete, you will be able to choose the C++11 standard by modifying the compiler flags.

Solution 4:

Navigate to the compiler settings by selecting “settings” and then “compiler”. Once in GNU GCC mode, go to the “Compiler settings” and select “Compiler flags”. Then, make sure to check the option for “Following the ISO C++11 language standard” under the g++ compiler.

That’s all there is to it. Take a look at this useful Youtube resource.

Which Version of Code::Blocks supports C++11, C++14 and C++17 Compilers?

I am in need of the current version of Code::blocks as I am currently using Code::Blocks 10.05 on Windows 7 with Server Pack 1 installed. Unfortunately, the Code::blocks I am using does not support the three compilers I mentioned earlier. I am unable to install VS due to data limit, but I require at least C++11. If possible, providing me with that version of Code::blocks would be greatly appreciated. Thank you.

Solution 1:

Your code cannot be compiled by Code::Blocks since it requires a more recent compiler version like GCC or Clang.

To acquire additional details, please consult the following: How to Enable c++17 Support in code blocks .

Solution 2:

The most recent version (20.03) of the compiler supports C++11, C++14, C++17, and C++20, depending on the capabilities of the compiler. To ensure that you always have access to a compiler that is up-to-date with the latest standards and can be easily upgraded with a single command from the shell, it is recommended that you install the compiler separately using the Msys2 toolchain.

There are different ways to download and install Code::Blocks on your computer:

  • Download the binary release

    This is the easy way for installing Code::Blocks. Download the setup file, run it on your computer and Code::Blocks will be installed, ready for you to work with it. Can’t get any easier than that!

    • Download a nightly build

      There are also more recent so-called nightly builds available in the forums. Please note that we consider nightly builds to be stable, usually, unless stated otherwise.

    • Other distributions usually follow provided by the community (big “Thank you!” for that!). If you want to provide some, make sure to announce in the forums such that we can put it on the official C::B homepage.

  • Download the source code

    If you feel comfortable building applications from source, then this is the recommend way to download Code::Blocks. Downloading the source code and building it yourself puts you in great control and also makes it easier for you to update to newer versions or, even better, create patches for bugs you may find and contributing them back to the community so everyone benefits.

  • Retrieve source code from SVN

    This option is the most flexible of all but requires a little bit more work to setup. It gives you that much more flexibility though because you get access to any bug-fixing we do at the time we do it. No need to wait for the next stable release to benefit from bug-fixes!

    Besides Code::Blocks itself, you can compile extra plugins from contributors to extend its functionality.

Thank you for your interest in downloading Code::Blocks!

Can’t complete `auto` variable of C++11 in Code::Blocks

Encountering this problem is a simple task, yet describing it can be quite challenging. To demonstrate, I have utilized Code::Blocks 13.12 and executed the code snippet in the subsequent manner:

auto **** = std::string("test"); ****.

Upon inputting the concluding

, an auto-complete context menu should appear, but unfortunately, it does not.

However, when I provide the appropriate form of


, such as:

std::string **** = std::string("test"); ****.

The expected
complete menu
appears, but it’s uncertain if the completion tool is compatible with C++11 or if it’s unable to suggest options for the




Navigate to the Settings menu and then open the Compiler section. Look for a C++ compiler that has the -std=c++ compiler flag, apply the flag and save the changes.

Code::Blocks 20.3 hay Code Blocks / Code Block là IDE miễn phí và phổ biến cho lập trình viên C, C++ và Fortran.

Code::Blocks là gì?

Mặc dù Code Block là IDE khá phổ biến nhưng không phải ai cũng biết đến nó. Code Blocks được coi là môi trường lập trình tích hợp (IDE – Integrated Development Environment) miễn phí, đơn giản và hiệu quả, đặc biệt là cho lập trình viên mới vào nghề. Code::Blocks có thể đáp ứng được nhu cầu lập trình cơ bản của người dùng ngôn ngữ C, C++ hay Fortran. Code Block được thiết kế với khả năng mở rộng và cấu hình toàn diện.

Giống như nhiều IDE khác, Code Blocks cung cấp cho bạn môi trường tích hợp bao gồm nhiều công cụ lập trình như chương trình viết mã lệnh (Code Editor), chương trình sửa lỗi (Debugger), chương trình mô phỏng ứng dụng (Simulator)… Nói 1 cách đơn giản hơn, Code Block là phần mềm bao gồm nhiều gói phần mềm khác để phát triển phần mềm, ứng dụng đa nền tảng.

Code::Blocks sở hữu giao diện đơn giản, đa tính năng và hỗ trợ đa nền tảng. Được xây dựng dựa trên nền tảng plug-in, CodeBlocks có thể mở rộng tính năng khi cài thêm plug-in. Chẳng hạn như tính năng sửa lỗi trên Code::Blocks được cung cấp thông qua chương trình mở rộng.

Tính năng chính của Code::Blocks

Tính năng nổi bật:
