Comipling Source code error

[SindhuVadde]

Hi, Thanks for sharing the code. We have cloned the source code but when we run the following script scripts/build-u-boot.sh we are getting following error. We have installed gcc version then also we are getting same error. How can i resolve this error.

The error message I see in your screenshot says *** Your GCC is older than 6.0 and is not supported.

So this error message means your arm-none-eabi-gcc version is older than 6.0. Or perhaps you have installed a newer arm-none-eabi-gcc but it's not in your $PATH.

When you type this:

arm-none-eabi-gcc --version

What version does it say? If it says earlier than 6.0 then that's the problem.

We have installed gcc version then also we are getting same error.

Do you mean you installed arm-none-eabi-gcc? That is the gcc you need to update, not gcc. The latest versions are here: https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads

Please install version 11.3.rel1, and follow the instructions on that site. When you are done installing, typing arm-none-eabi-gcc --version will say:

arm-none-eabi-gcc (Arm GNU Toolchain 11.3.Rel1) 11.3.1 20220712

Hi, Thanks for the reply. We have downloaded [arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-elf.tar.xz] from this https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads. For adding PATH Variable we refer the following page.https://docs.oracle.com/cd/E19062-01/sun.mgmt.ctr36/819-5418/gaznb/index.html And Here is my path /home/username/Downloads. I added path. Still it is showing the same error. Am i downloaded wrong tool chain or PATH setting procedure. Here is the path when i use echo $PATH

Ah, yes I see now. You downloaded aarch64-none-elf which is the wrong compiler. You need arm-none-eabi.

This is the one you need: arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-eabi.tar.xz

Also, you need to add the path to the arm-none-eabi-gcc binaries to your PATH, not just the path to your download directory. Please keep in mind that this has nothing to do with STM32MP1 or with this repo, it's really about learning bash commands and how to install software on your particular linux distribution. But I can try to help a little. You will need to learn some basic things about Linux and about using the command line, so keep reading basic Linux tutorials and basic command line usage.

Here is a relevant thread from the arm-gcc forum: https://community.arm.com/support-forums/f/compilers-and-libraries-forum/52159/how-to-install-gnu-arm-embedded-toolchain

So, after you download and then unzip/untar the file, you need to add to $PATH the path to the actual file named exactly arm-none-eabi-gcc. For example if you downloaded and extracted the files into /home/username/Downloads then you would do this:

export PATH=/home/username/Downloads/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-eabi/bin:$PATH

Notice I added bin/ to the end, because this is where the binaries live in the extracted files. Also notice I put the new path to the arm-none-eabi-gcc binary in the front of $PATH, rather than after it. This is to give priority to the newly installed binaries over any older versions you might have.

Make sure that /home/username/Downloads/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-eabi/bin is an actual directory on your computer. I'm just guessing what it might be, so you must verify on your own system. If you type this:

ls -l /home/username/Downloads/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-eabi/bin

It should list the files in that directory, including one named arm-none-eabi-gcc. If it doesn't, then you need to figure out where you actually downloaded and extracted the files before adding this path to PATH

Again, I must stress strongly: you will need to learn basic command-line usage (also known as shell, which is typically bash) in order to make much progress. Here are some resources:

Hi, @SindhuVadde just checking if you've made any progress.
