Solved Undefined symbol "_ZTVN10__cxxabiv117__class_type_infoE

[hruodr]

I have a problem compiling a program in FreeBSD 11.4 that I did not have before.
Well, it compiles, but when running I get the above error:

Undefined symbol "_ZTVN10__cxxabiv117__class_type_infoE

It seems it has to do with compiler, gcc10.

The program is the shared library libMk4tcl2.4.9.7.so for tcl8.4. Ldd gives no dependency:

# ldd /usr/opt/tcl84/lib/Mk4tcl2.4.9.7/libMk4tcl2.4.9.7.so
/usr/opt/tcl84/lib/Mk4tcl2.4.9.7/libMk4tcl2.4.9.7.so:
#

Any hint?

Thanks!

add -lc++

add -lc++

Thanks. That worked. What did change in FreeBSD that it became necessary?

dunno, i think i first encountered it when moving from gcc to clang
i think libstdc++ (gcc) was pulled in by default but im not sure
