Subject: bug#50494: 28.0.50; OpenBSD pgtk build fails due to the use of libdl
Date: Fri, 10 Sep 2021 02:34:35 +0300

Note: I'm sending this from a Linux machine but this was observed on an
OpenBSD laptop which I currently can't use, however since Emacs 28 is
releasing soon I thought I might as well report this since I happen to
know the solution to this bug.

At some point during a pgtk build (configure --with-pgtk) ld(1) will
error out since it can't find libdl, causing the build to fail.
This occurs since on OpenBSD libdl doesn't exist, instead providing the
same facilities through libc (this is a common issue when porting
programs to OpenBSD).

Workaround:
1. Run ./configure --with-pgtk
2. Open src/Makefile
3. Find the line PGTK_LIBS=...
4. Remove -ldl (the last library listed)
5. Run make

This produces a working Emacs AFAICT.

Sorry for not providing the specific error message returned by ld, and
not reporting this from the affected machine.  If this is critical, I
could try to get that laptop to work again and give some more
information.

Regards,
Daniel
