Clang is mainly for the benefit of Mac (recent OSX, macOS come with
clang only). The main differences are compiler options, warnings in
Ardour does however compile with clang on GNU/Linux, we do use it for
static analysis: https://nightly.ardour.org/list.php#clang_analyzer
What version of clang are you using? Could you post a compile log how it
fails or file a bug ticket?

We do strive towards clean warning-free code. But for a project this
large that supports 20+ different architectures, more than 4 different
compilers (incl MSVC), and depends on 30+ 3rd party libs, -Werror is not
reasonable. There are also plenty of warnings from 3rd party
