#MCUXpresso-IDE Program "arm-none-eabi-c++" not found in PATH

Hello,

I am reaching out to you regarding an issue I am experiencing with the latest version of #. I recently changed computers and installed IDE v25.6 [Build 136] released on June 27, 2025. After importing my project from Git, it does not compile. I receive the following error messages: "Program 'arm-none-eabi-c++' not found in PATH" and "Program 'arm-none-eabi-gcc' not found in PATH.

On the previous version of (v24.12 [Build 148]), this project works perfectly. Interestingly, I am able to create new projects in the new version and compile them without any problems. Additionally, I can import and compile other projects, but one particular project is problematic.

Upon comparison, I noticed that some Path Variables are missing in the Link Resources for this specific project: cmsis_pack_root, $, cmsis-rte, and $.

Could you please help me resolve this issue?

Hi @Brainiac

New projects work fine → toolchain is correctly installed in v25.6.

So i think you can check Toolchain Settings

Right-click the problematic project → Properties

If it still hasn't been resolved, you can link your git. I can try.

Hello @Harry_Zhang ,

Thank you for your response. I have just done the checks, and the parameters of the toolchain are identical. If it helps you understand the problem, I have installed on my new PC the version MCUXpresso IDE v24.12 [Build 148] [2025-01-10], and the project works perfectly. Therefore, it is not an issue with the OS.

Unfortunately, I am unable to attach my GIT with the project.

Hi @Brainiac

So based on your description, this may be an issue with MCUXpresso IDE 25.03.

Unfortunately, I am unable to obtain a more detailed description of the issue and cannot reproduce it, so I am unable to locate the root cause.
