Does not show line number when link with boost_stacktrace_addr2line.
Environment
Package Name/Version: boost/1.76.0 Operating System+version: Linux Ubuntu 20.04.3 LTS (in docker) Compiler+version: GCC 9 Docker image: ubuntu/latest
Description
I find it does not show the line number if I link with boost_stacktrace_addr2line, but if I link with boost_stacktrace_backtrace, the line number shows up. The stacktrace is always shown but the line number is only shown if I link with boost_stacktrace_backtrace rather than boost_stacktrace_addr2line which is different with what the document says.
The other linked libraries are always the same which are backtrace and dl, and the addr2line is at the path /usr/bin/addr2line.
I have tried to install boost with conan and apt respectively, and the result is the same.
Did I misunderstand the document? And is it expected?
