SQLite.so not linked with libstdc++, undefined symbol: _ZTVN10__cxxabiv117__class_type_infoE

[dagbdagb]

So, this issue belongs with slimserver-vendor, but that project does not allow for opening tickets.

0. Environment
   gcc (Gentoo 10.2.0-r5 p6) 10.2.0
   Copyright (C) 2020 Free Software Foundation, Inc.

This is perl 5, version 32, subversion 0 (v5.32.0) built for x86_64-linux-thread-multi
(with 76 registered patches, see perl -V for more detail)

On my system (gentoo) buildme.sh will build with clang out of the box, if clang is found. I believe the consensus is that additional perl modules should be built with the same compiler as the main environment?

export CC=gcc
export CXX=g++
export GXX=g++ 

.....ensures that the entire enchilada is built with the preferred compiler, on my system.

SQLite.so needs to be linked with libstdc++. For some reason, this lib is not found during the build_module run tests.

To get around this, I built slimserver-vendor with the '-t' option (skip tests) to buildme.sh, then rebuilt SQLite.so manually, like this:

cd DBD-SQLite-1.58/
x86_64-pc-linux-gnu-g++  -shared -O2 -pipe -march=native -fomit-frame-pointer -Wl,-O1 -Wl,--as-needed -Wl,-Bsymbolic  SQLite.o dbdimp.o sqlite3.o  -o blib/arch/auto/DBD/SQLite/SQLite.so ../build/lib/libicuuc.a ../build/lib/libicudata.a ../build/lib/libicui18n.a  -L/home/dagb/gits/slimserver-vendor/CPAN/DBD-SQLite-1.58/../build/lib -licudata_s -licui18n_s -licuuc_s  

Copying the result to the right location in the slimserver directory makes for a functional slimserver.

I was able to get here, and I post this half-assed workaround for the benefit of other tinkerers. I assume someone versed with the code in question is much better suited to decide where the actual bug is, and how to fix it properly.

Warning (mostly harmless): No library found for -lstdc++ is a lie.

Thank you for the continued maintenance of Logitech Mediaserver!

The issue here is that Gentoo does not create a link for libstdc++ in /usr/lib. It could be found only in /usr/lib/gcc/x86_64-pc-linux-gnu/... (depends on arch)
Perl MakeMaker (used to create Makefile) will not look into gcc lib folder (you can verify lib path with perl -V:libpth command), so it won't find libstdc++ and will drop -lstdc++ from gcc cmd line.
Easiest solution would be to create libstdc++ symlink in /usr/lib
