Are you tired of seeing the dreaded “arm-poky-linux-gnueabi-gcc not found” error when trying to build your project with Bitbake? Don’t worry, you’re not alone! This error can be frustrating, but it’s actually quite easy to resolve. In this article, we’ll take a deep dive into the world of Bitbake and explore the reasons behind this error. We’ll also provide you with step-by-step instructions on how to fix it, so you can get back to building your project in no time!
What is Bitbake?
Before we dive into the solution, let’s quickly cover what Bitbake is and why it’s used. Bitbake is a build automation tool used in the OpenEmbedded project, which is a framework for building embedded Linux systems. It’s a Python-based tool that uses recipes to build and configure target images for various platforms. Bitbake is commonly used in the development of Linux-based devices, such as routers, set-top boxes, and other embedded systems.
The Error: Arm-Poky-Linux-Gnueabi-Gcc Not Found
So, what does the “arm-poky-linux-gnueabi-gcc not found” error mean? In simple terms, it means that Bitbake can’t find the arm-poky-linux-gnueabi-gcc compiler, which is required to build your project. This compiler is a cross-compiler that’s specific to the ARM architecture, and it’s used to compile code for ARM-based devices.
The error usually occurs when the compiler is not installed or not properly configured on your system. It can also occur if the compiler is installed, but Bitbake can’t find it due to incorrect PATH settings or missing dependencies.
Fixing the Error: Step-by-Step Instructions
Now that we understand the error, let’s fix it! Here are the step-by-step instructions to resolve the “arm-poky-linux-gnueabi-gcc not found” error:
Step 1: Install the Arm-Poky-Linux-Gnueabi-Gcc Compiler
The first step is to install the arm-poky-linux-gnueabi-gcc compiler on your system. You can do this by running the following command:
sudo apt-get install gcc-arm-linux-gnueabiThis command installs the arm-linux-gnueabi-gcc compiler and its dependencies on your system.
Step 2: Update Your PATH Environment Variable
Once the compiler is installed, you need to update your PATH environment variable to include the path to the compiler. You can do this by adding the following line to your ~/.bashrc file:
export PATH=$PATH:/usr/lib/gcc-cross/arm-linux-gnueabi/4.8/binThis line updates your PATH environment variable to include the path to the arm-linux-gnueabi-gcc compiler.
Step 3: Verify the Compiler Installation
To verify that the compiler is installed correctly, you can run the following command:
arm-poky-linux-gnueabi-gcc --versionThis command should display the version of the arm-poky-linux-gnueabi-gcc compiler installed on your system.
Step 4: Configure Bitbake to Use the Compiler
Finally, you need to configure Bitbake to use the arm-poky-linux-gnueabi-gcc compiler. You can do this by adding the following lines to your local.conf file:
TCLIBC_TOOLCHAIN_VERSION = "linaro-4.8"
Toolchain Tmin = "arm-poky-linux-gnueabi-gcc"This configuration tells Bitbake to use the arm-poky-linux-gnueabi-gcc compiler for building your project.
Step 5: Re-Run Bitbake
Once you’ve completed the above steps, you can re-run Bitbake to build your project. If everything is configured correctly, you should no longer see the “arm-poky-linux-gnueabi-gcc not found” error.
Troubleshooting Tips and Tricks
If you’re still experiencing issues after following the above steps, here are some troubleshooting tips and tricks to help you resolve the error:
- Check your PATH environment variable: Make sure that your PATH environment variable is set correctly and includes the path to the arm-poky-linux-gnueabi-gcc compiler.
- Verify the compiler installation: Run the command “arm-poky-linux-gnueabi-gcc –version” to verify that the compiler is installed correctly.
- Check your local.conf file: Ensure that your local.conf file is configured correctly and points to the correct compiler.
- Try a different compiler version: If you’re still experiencing issues, try installing a different version of the arm-poky-linux-gnueabi-gcc compiler.
Conclusion
In conclusion, the “arm-poky-linux-gnueabi-gcc not found” error is a common issue that can be resolved by installing the arm-poky-linux-gnueabi-gcc compiler, updating your PATH environment variable, and configuring Bitbake to use the compiler. By following the steps outlined in this article, you should be able to resolve the error and get back to building your project with Bitbake.

Frequently Asked Question
Having trouble with Bitbake and that pesky “arm-poky-linux-gnueabi-gcc not found” error? Relax, we’ve got you covered!
Q1: What’s the deal with this error? Is Bitbake broken?
Don’t panic! The error message “arm-poky-linux-gnueabi-gcc not found” is not a sign of Bitbake being broken. It simply means that the build process can’t find the required compiler, `arm-poky-linux-gnueabi-gcc`, which is part of the Yocto Project’s toolchain.
Q2: Why does Bitbake need this special compiler, anyway?
The `arm-poky-linux-gnueabi-gcc` compiler is a cross-compiler, specifically designed for building ARM-based projects. Since Bitbake is used for building embedded systems, it needs a compiler that can generate code for the target architecture (in this case, ARM). This special compiler ensures that the resulting binaries are compatible with the target device.
Q3: How do I fix this error? Is there a magic fix?
No magic fixes here, but a simple solution! You need to ensure that the Yocto Project’s toolchain is installed and configured correctly. Check that you’ve run the `source oe-init-build-env` command to set up the build environment, and that the `-arm-poky-linux-gnueabi-` compiler is present in your PATH. If you’re still stuck, try reinstalling the Yocto Project’s toolchain or seeking help from the community.
Q4: What if I’m using a virtual environment or Docker? Do I need to install the toolchain inside the container?
Good question! If you’re using a virtual environment or Docker, you’ll need to install the Yocto Project’s toolchain inside the container or virtual environment. This ensures that the compiler is available within the build environment. Just remember to update your `PATH` environment variable accordingly.
Q5: This is all so confusing! Where can I learn more about Bitbake and the Yocto Project?
Don’t worry, we’ve all been there! The Yocto Project has an amazing documentation and community resources. Start with the official Yocto Project documentation and tutorials. You can also explore online forums, such as the Yocto Project mailing list or Stack Overflow, for more specific questions and answers.
