Disable code analysis on a per file basis? [message #734842]

Hi all!

I am trying to disable the code analysis tool on a per file basis.

I found two different ways to ignore files for the "Run C/C++ code analysis" context menu operation.
In the build configuration, we can either exclude files to be ignored from build or we can add the to the code analysis rules' exclusion pattern.

But in both case if the user opens an ignored file, the code analysis is performed anyway at file opening. Is there a way to avoid performing this code analysis when opening an editor on a file that should be ignored by the code analysis tool?
Is it a bug?

Thanks for any help

I am trying to do the same thing in Eclipse-4.2, with CDT-8.1.

I want Code Analysis to ignore files with a specific extension (.m4).

Has anyone done this?

Could this be due to the editor used to open the file?
If you chose "Open With" -> "Text Editor", does the Code Analysis still run on the file?

Hello,

as far as I know Code Analysis uses the same file types as CDT.

So you could try this:
Open "Windows -> Preferences -> C/C++ -> File Types"
and remove the *.m4" from the list of the files types.

Open "Windows -> Preferences -> General -> Editors -> File Association"
and add a new file type *.m4 to this list and associate the file type to your preferred editor, probably C/C++ Editor.

Maybe you must trigger a index rebuild after changing the setting.

If that does not work for you you probably could use this method:

Open "Windows -> Preferences -> C/C++ -> Code Analysis"
Here you can customize each checker to exclude or include specific files.

A short feedback which one of this version work for you is welcome.

regards,
Klaus

Open "Windows -> Preferences -> C/C++ -> File Types"
and remove the *.m4" from the list of the files types.

.m4 is not listed.

Open "Windows -> Preferences -> General -> Editors -> File Association"
and add a new file type *.m4 to this list and associate the file type to your preferred editor, probably C/C++ Editor.

.m4 already exists, associated with "Autoconf Editor (default)".

Changing to /C++ Editor and reopening the file, I don't see the errors any longer.

No need to re-index (Right click Project->Index->Rebuild)

Perfect. Thank you.
