GCC 12.1 and C++23 <stacktrace>

GCC 12.1 and C++23 <stacktrace>

[Helmut Zeisel]

I tried to use C++23 <stacktrace> with GCC 12.1.
I configured GCC 12.1 with

 --enable-libstdcxx-backtrace=yes

built, and installed.
I built my test program with

-std=c++23 -lstd++_libacktrace

(cf. https://stackoverflow.com/questions/72341483/how-can-i-generate-a-c23-stacktrace-with-gcc-12-1 )

but get the error message

/usr/bin/ld: cannot find -lstd++_libacktrace: No such file or directory

Do I need other or additional options? Where can I check whether libstd++_libacktrace was really built?

Thank you,

Helmut

You spelled it wrong. It's stdc++ not std++
