So, two examples of needing libgcc_s.so.1 from the above
list are (not from a detailed match of your environment
but still suggestive):
# ldd /usr/lib/libc++.so.1
/usr/lib/libc++.so.1:
libcxxrt.so.1 =3D> /lib/libcxxrt.so.1 (0x312e6618b000)
libgcc_s.so.1 =3D> /lib/libgcc_s.so.1 (0x312e6575b000)
libc.so.7 =3D> /lib/libc.so.7 (0x312e61cf7000)
# ldd /lib/libcxxrt.so.1
/lib/libcxxrt.so.1:
libgcc_s.so.1 =3D> /lib/libgcc_s.so.1 (0x2a835b629000)
libc.so.7 =3D> /lib/libc.so.7 (0x2a8358f46000)
FreeBSD has its own libgcc_s.so.1 that is used sometimes,
even when no lang/gcc* port nor a system-gcc/g++ is involved.
This is normal for FreeBSD. The lang/gcc* ports provide their
own libgcc_s.so.1 instances but it takes -Wl,-rpath=3D. . .
use to cause bindings to the appropriate port's file instead
of using the FreeBSD one. On at least aarch64, FreeBSD's
libgcc_s.so.1 need not be sufficient for use by code generated
by a lang/gcc* compiler (C or C++). The file from the port
may be required.
