linking issues

[cwebdesign]

I installed RE-flex on macos using homebrew. I use g++-14 from homebrew.
I'm trying to link in the generated code in my app with the reflex library, but I get errors:

Any ideas on what I could do?
My code links properly on other platforms.

[genivia-inc]

My typical development environment is MacOS M1 (arm64) and haven't had any problems compiling and linking with clang. I've verified that c++ -std=c++14 works fine, where c++ runs clang++ version 14.0.0.

Check with nm:

$  nm -gU lib/libreflex.a
