I assume this may be related to the incompatible versions of the tools. How to handle this?

With the new versions of newlib, the macro should read (ptr)->__cleanup), not (ptr)-> __sdidinit).

Fixed on 2022-10-09.

I have just tried on Eclipse Marketplace. The newest version is still 6.3.0. I will wait a bit until it appears on the Marketplace to give it a try. Many thanks!

Ah, sorry for the misunderstanding, the fix is only in the project git, it was not published yet, due to a problem with the GitLab build infrastructure.

I'll make the release when possible and let you know.

Great! Thanks!

As a workaround, you can also manually patch that faulty macro, it is a simple change.

[eraus]

Sounds good. I see your diffs.

6.3.1 was published.

Please check it and confirm it also works in your environment.

I see 6.3.1 published. Here are what I have tried.

1. When I went to the Eclipse Marketplace, I see my 6.3.0 was automatically updated to 6.3.1. As I am a new user for Eclipse, I am not sure if this was done automatically or not. To make sure, I removed it and reinstalled 6.3.1.
2. The xPack tools I installed was recognized with the new 6.3.1.
3. I then created a new Blinky project, I see that the syscalls.c still has (ptr)->__sdidinit).
4. I have not patched up the files yet. I am still in the process trying to figure out where the original files are saved. Before installing 6.3.1, I thought the original syscalls.c file was part of 6.3.1. Now that you have fixed the issue in the repo, but I still have this issue, I am not sure where it came now. Please shed some lights here, and I will do some more tries after this.

I'm afraid you messed something :-(

I suggest you download a fresh Eclipse Embed CDT, create a new workspace and install the plug-ins.

The normal way is to simply update the Eclipse, but once something goes wrong, sometimes there is not much to do to fix it than restart from scratch.

[eraus]

I started a new workspace, and everything worked well with the newest versions of tools. Many thanks!

Thank your help!
