>Description:
ld(1) from GCC 7.5.0 on NetBSD 9.0_STABLE (GENERIC) #0: Mon Aug 17 14:38:32 UTC 2020 fails to link a shared library (libncurses) with this error:

ld: /usr/lib/crt0.o: relocation R_X86_64_PC32 against undefined hidden symbol `__fini_array_start' can not be used when making a shared object

>How-To-Repeat:
1. Download ncurses from https://invisible-mirror.net/archives/ncurses/current/ncurses-6.2-20200817.tgz
2. Untar, configure.
./configure --prefix=/opt/ncurses --with-shared
3. make

Please quote the full compiler / linker invocation that fails, and ideally
repeat it with -v added and show full output.

That's a default (and has been removed), and not relevant here, I think.
There seems to be a difference between passing ``-Wl,-shared'' and passing =
``-shared'':
With ``-shared'', the library is produced without error:

OK. I've tried gcc-8.3.0 & gcc-10.2.0, clang-8.0.1 & clang-10.0.1. None of them accept ``-Wl,-shared'' as a synonym for ``-shared''.
I'll report a bug with the ncurses maintainer, instead.

-Wl,-shared means "pass -shared to the linker and do nothing else"
while -shared means "tell the compiler driver to build a shared
library", which includes both passing -shared to the linker and also
doing other things. Without the other things, you'll among other
things get the wrong crstuff and it won't work.

"Without the other things, you'll get the wrong crtstuff and it won't

That explains things very well. Thanks.

When discussing this issue with Tom Dickey on the ncurses mailing-list,
he pointed out that passing ``-Wl,-shared'' instead of ``-shared''
works on NetBSD-8.0 for creating a shared library. His build log is
here:
https://lists.gnu.org/archive/html/bug-ncurses/2020-08/msg00086.html
I have access to a NetBSD-8.1 system (gcc (nb3 20180905) 5.5.0) and,
I can confirm that ``-Wl,-shared'' works there, too.
Seems a bit odd, no? Can you explain what's going on here?
Thanks,

It can work by luck (and presence or abscense of other flags, like
-fpie). It still is not the right command.
