Eclipse ninja: build stopped: subcommand failed

[Bubar80]

Hello,
For about a week I am trying to get projects running on Eclipse with mixed results.
Sometime I can compile and debug with no issues and then suddenly, I get the "ninja: build stopped: subcommand failed" message at the end of a compile and from there, my project will not generate the .bin or .elf file anymore.

Even if I delete this project from the drive, as long as I re-create an empty project with the same name, I get the the same error message and .bin/.elf files are not generated.
I tried deleting the ".metadata" folder with no changes.

My only way around this is to re-create a project with a different name.
It works for a while and then after doing some code changes and a few successful compiles, I get again the ninja error message. Reverting the code do not do anything.
But making a new project using the same code but a slightly different name does work for a while.
My project file path do not have space.
I had "." in the file name and I replace it with "_" with no changes.
Making the project name longer of shorter doesn't seem to change anything.

It seems to me that at some point a setting changes in my project and that Eclipse or the IDF toolchain associate those changes to the project name and save this somewhere. I have not been able to find where this association is saved.

Any idea if there is a file I could flush so that I don't need to change project name all the time?
Or does anybody knows why I get a "ninja: build stopped: subcommand failed" error message?

Thanks for any help.

Can you post the messages of such a compile here? The 'ninja failed' message tends to be caused by an error earlier (sometimes much earlier) in the compile process.

Hi,
See below the end of the compile log as there is a 60 000 character limitation on the forum. Let me know if you need more log.

I see now that there are 2 other error messages in the compile log. Not sure what they mean...

That ccache error clarifies things... and the base directory plus the path of the specific file the error is on come dangerously close to the Windows 260 char path size limit. I think this topic is related; you could try and see if any of the solutions there work for you.

[Bubar80]

Yes, that was it!
I have moved my workspace folder to get a shorter path, and sure enough, it is stable now.

The thing that surprises me is that when the workspace path is too long, I am able to compile and debug for a while until suddenly it is no more possible. It may be happening when I include an header file which is outside the workspace, not sure yet.
But one thing is sure, ones it stop working, there is no way back unless I recreate a project with a different name (same character length, same path).

Anyway, I will also try some of the solutions from the post you mentioned.
The 260 characters limit may become an issue for me as some of the code I use is shared with other projects and is in other folders.

Thanks for the help.
