Sonar scanner for C programming language code is not working

As part of BU we have project where we need to run the Sonar scan against it.

code is “.c” files

scan has to be performed against “.c” files

approached followed:- C/C++/Objective-C

first time we started setting up sonar scan for this project

The sonar scan we started doing first on developers laptop.

More details:-

we are able to run the build wrapper command which includes the build command → it is working fine with out any error → but here the issue is it is generating json dump file which is empty (no .c files captured) as shown below

we tried with cleaning and perform build wrapper build command but still same issue where the json dump file has no .c files

for clean rebuild also same issue

Hi,

Can you provide a few more details? Specifically, what version of SonarQube are you on? What’s your compiler? What’s your full compile command, including the build-wrapper?

 
Thx,
Ann

Sonar scanner for C programming language code is not working

As part of BU we have project where we need to run the Sonar scan against it.

code is “.c” files

scan has to be performed against “.c” files

its not like it worked before and stopped working all of the sudden, but it didn’t worked from day one

The sonar scan is not working manually on developers laptop as well as part of the Azure Devops pipeline

More details:-

the json dump file is been generated by build wrapper successfully and when we provide all details for sonar scanner command and start execution it goes to the point where it gets the location of json file and start analyzing . → but this task takes for ever

after almost 20 hours it is able to analyze on 4 files.

we included only required folder and files which are needed for the project

Even this is making the server to be 100% CPU utilized.

even no errors are reported. its just taking time and time and nothing is getting displayed at pipeline log end or even when done via manually

We made some many changes for sonar scanner command (all possiblity changes but no luck)

Hi,

I just found your other topic, created minutes before this one with essentially the same content. Please don’t do that.

I’ve moved the contents of that topic here, and I see from it that you’re on SonarQube 9.2. The current version of SonarQube is 9.8. Please upgrade and see if the problem persists. If it does, then these questions still stand:
