10 months ago I have exactly the same exception. I wanted to compile pdlib to get facerecognition work.
System: TrueNAS-13.0-U6.1

System: FreeBSD system 13.2-RELEASE-p8 FreeBSD 13.2-RELEASE-p8 GENERIC amd64 Issue: Unable to compile PDlib due to 'ld: error: unable to find library -lstdc++' and 'Error code 1' Expected behaviour: PDlib compiles on FreeBSD
Context: Installing Dlib, following this procedure works: https://github.com/matiasdelellis/facerecognition/wiki/PDlib-Installation
Next step, installing PDlib is met with an error during the 'make' command, when following: https://github.com/matiasdelellis/facerecognition/wiki/PDlib-Installation
git clone https://github.com/goodspb/pdlib.gitcd pdlibphpize./configuremake==> issue arises here 'Error code 1' and 'ld: error: unable to find library -lstdc++', see belowsudo make installPossibly because FreeBSD uses clang, not gcc. I have tried multiple work arounds, even removing lstdc from the makefile, but unfortunately this results in crashes when trying to load the .so in PHP.
Maybe it is possible to include clang or allow for a more generic way of compiling?
