Different results for SonarLint 4.1.0 vs. SonarCFamily 6.1 plugin

sonarlint
sonarcfamily
(Petermbauer) #1

After some time i wanted to try the current SonarLint again but so far it does not seem to work well for us:

  • SonarQube 7.6, SonarCFamily plugin 6.1, SonarLint 4.1.0.201901311043 Eclipse plugin

I updated all project bindings several times and have not changed the used Quality Profile. No errors in the SonarLint console.

Issues:

thx,

Hi @petermbauer,

is it a header file?

(Petermbauer) #3

No, all these are implementations in .c files.

thx,
Peter

My best guess is that your project in Eclipse CDT is set in a way that it doesn’t pass properly the configuration to SonarLint making the analyzer behaving in a cascade of recovery/errors. Do you know the type of your project in Eclipse CDT?

Could you please enable SonarLint verbose log and provide me such log? Thank you.

I am using CMake and the cmake4eclipse plugin (https://github.com/15knots/cmake4eclipse) for the project.

This is the output in the SonarLint console. The mentioned build-wrapper-dump.json does not exist, not even the folder sonarlint6649437851434476700 is there.

You can see that Reg_flash.h is not found, that’s why you don’t get good results:

It means that eclipse is not passing the good configuration to SonarLint.
If you open Properties page for Com_Fl.c, do you see good configuration for Path and Symbols and Preprocessor Include Path?

(Petermbauer) #7

Include dirs and so on are set in CMake only so Eclipse does not know about it (its not even a CDT Project). So it looks like this makes SonarLint useless for us.

thx,
Peter

Hi @petermbauer,

I am pretty sure that it is possible to generate Eclipse CDT project from cmake project with “good” configuration.

(Petermbauer) #9

Hi @mpaladin,

i tried to manually add the include dirs to the Eclipse configuration, now the results are the same as in SonarQube :grinning:. I will check whether it is possible to somehow import the include directories from CMake with the cmake4eclipse plugin, otherwise these would have to be managed twice.

thank you for your help,
Peter

Hi @petermbauer,

good to know you made progress. I am not an Eclipse CDT user but I know there are multiple ways to import cmake projects, and unfortunately I don’t know what is the recommended options.
