libclang-cpp12-dev 1:12.0.0-3ubuntu1~20.04.3 (armhf binary) in ubuntu focal

 Clang project is a C, C++, Objective C and Objective C++ front-end
 based on the LLVM compiler. Its goal is to offer a replacement to the
 GNU Compiler Collection (GCC).
 .
 Clang implements all of the ISO C++ 1998, 11, 14 and 17 standards and also
 provides most of the support of C++20.
 .
 This package contains the Clang C++ library.
 .
 The C++ Interface to Clang provides an API that exposes
 facilities for parsing source code into an abstract syntax tree (AST),
 loading already-parsed ASTs, traversing the AST, associating physical source
 locations with elements within the AST, and other facilities that support
 Clang-based development tools.
 .
 This package contains symlinks without a version number, which needed by
 linker at build time.
