<div dir="ltr"><div>Hi Dimitry, this definitely worked. I am passed by the linking errors regarding libc++ or similar.

If you only want the clang static analyzer, there is no need to check out and build libc++ as part of the process. The rest of the build can just use the system C++ library, which will be libstdc++ on Xubuntu.<br>
<br>
That said, without the full build log, it is hard to say what went wrong. Specifically, which references were undefined?<br>
