Hello everyone,

I have 2 simple questions regarding the long-defunct SonarLint for Visual Studio 2015 flavor. I’m aware that it was dropped and is unsupported, as well as the Visual Studio version, but please hear me out.

We have legacy code running on Visual C++ 6 (1998) and 9 (2008) that is stuck with Visual Studio 2015 due to stuff getting dropped within Visual Studio 2017 and newer (actual internals of the IDE we rely on, not dependencies). For these parts, we cannot update the Visual C++ or Visual Studio version, but I’d like to rely on my beloved SonarQube for IDE (back then still called SonarLint) when maintaining it - it is a bit critical.

I found the latest version supporting it to be 4.38.0.36876 and will install it if there is no newer version for VS2015? It is not on the marketplace anymore, and I will rely on the VSIX file, therefore.

My second question is about the CFamily analyzer embedded. Based on the version above, and digging through the code, it is 6.26.0.36731. I could not find any related documentation for this old version, except for the current 2025.1 LTA documentation saying that all Microsoft C/C++ compilers and any version are supported. With that old version, was it already the case?

Thanks in advance for your response! And again, yes, these software in question, as well as the SonarQube for IDE versions, are highly outdated - I’m aware of that.
I won’t need any further support with this, then, I think I can manage myself :smiley:

Cheers :clinking_glasses:


PS: If you read this and think to yourself “oh my” - I’m with you.

Hello @EclipseWizard,

Version 4.38 seems to be indeed the last version that supports VS2015. In the version 5.0, the support for it has been dropped.

Here is the list of the supported C++ versions for SonarQube for Visual Studio. I am not sure if that was still the case for 6.26.0.36731 as it is no longer supported.

Hope that helps!
