Hello there.
I found the reason.
The c++ features used inside Symbolize.h is std c++ 14, but c++ options
listed in wscript in all projects under rtems-tools has -std=c++11,
which cause it failed to build.
I manually modified the options in wscript, it all compiled
The next question is: how can I put a patch to let RSB build with
-std=c++14?
Thanks for having a look a this. I think this bug was already fixed by:

trace: Use c++14 instead of c++11 if possible
llvm version 10 uses features from c++14 standard in the headers. With
that, the record/record-main-lttng.cc doesn't build any more. This
patch
makes sure that c++14 is used if it is available.
Updates #4495
Unfortunately, this fix is not included in the RTEMS 5.1 release. It
will be included in the 5.2 release.
