Cannot resolve __cxa_pure_virtual in ports of gcc11/12/13

Hi,

As the subject states - With gcc versions upto 10, we had no problem
resolving __cxa_pure_virtual from libsupc++ - but with gcc11 onwards we
cannot seem to resolve it from there? I can add an object file with the
symbol in and it is resolved fine, and the symbol appears to be in
libsupc++?

kalam@EVO64:~/builds/pc-x86_64-gcc13-clean$
bin/linux-x86_64/tools/crosstools/x86_64-aros-nm
bin/linux-x86_64/tools/crosstools/lib/gcc/x86_64-aros/13.0.1/libsupc++.a |
grep "pure_virtual"
                 w __cxa_pure_virtual
0000000000000000 T __cxa_pure_virtual
kalam@EVO64:~/builds/pc-x86_64-gcc13-clean$

Does someone have an idea why this may be/where to look - or how to resolve
it?

Yours,
Nick Andrews.

I'm experiencing something similar.  At link-time I'm not getting dladdr
from libdl.so.  The symbol is in libdl.a, but I can't verify libdl.so as it
is striped.  It is at least defined in dlfcn.h.  Compiling with -static
doesn't work either.
