        <pre>Compiling of lldb under Red Hat Enterprise Linux 7 (with SWIG 2 from the repo)
results in this error message:

Scanning dependencies of target swig_wrapper
[ 12%] Building LLDB Python wrapper
/home/build/devel/clang/11.0.0/llvm-project-11.0.0/lldb/bindings/./python/python-typemaps.swig:484:

In file python-typemaps.swig, line 484 one finds the C++11 keyword "delete":

481 struct Py_buffer_RAII {
482   Py_buffer buffer = {};
483   Py_buffer_RAII() {};
484   Py_buffer &operator=(const Py_buffer_RAII &) = delete;
485   Py_buffer_RAII(const Py_buffer_RAII &) = delete;
486   ~Py_buffer_RAII() {
487     if (buffer.obj)
488       PyBuffer_Release(&buffer);
489   }
490 };

C++11 support requires at least SWIG 3. So in my opinion the minimum
requirement should be changed.

After installing SWIG 3 from the CentOS 7 repo the build works fine.</pre>
