10.5 added contents of cmake/os/FreeBSD.cmake in c991efd9c3.
in the merge to 10.11, d002b1f removed this file.
In the past FreeBSD.cmake was removed in 5369df741b
in the 10.11 branch as no remaining code was needed. The combination
of this and the merge lead to the the file being removed. My assumption is
this was a non-stable branch at the time.
The purpose of this patch is clang doesn't have /usr/local/lib in
the path. As such there are various depedency linkages that will fail.
For example pcre and libfmt.
On all Unix platforms, link libexecinfo as system library,
if it contains backtrace_symbols_fd function, and libc does not contain
this function
Also remove cmake/os/OpenBSD.cmake, as after the fix it serves no purpose.
Accidental change in compile-time definitions for FreeBSD
Revert the accidental setting of "HAVE_BROKEN_REALPATH"
on current versions of FreeBSD,
do it for both autotools ("configure.in")
and cmake ("cmake/os/FreeBSD.cmake").
is not needed any more with current versions of FreeBSD.
(Entries 52410 and 52412 in the Bug DB)
That change is based on Dan Nelson replying on the
FreeBSD mailing list, freebsd-questions@freebsd.org
in a thread running from 2010-Apr-29 to 2010-May-1 titled
"Need info about FreeBSD and interrupted system
calls for MySQL code"
Also, ensure the cmake settings correspond to the autotools
ones: Add "HAVE_BROKEN_REALPATH" to cmake.
cmake/os/FreeBSD.cmake:
With current versions of FreeBSD, threading is not done on
the user-level any more, so the huge "net retry count"
is not needed any more.
However, it is still being kept as a comment for now,
so that it can be re-activated should the need arise.
In addition, set "HAVE_BROKEN_REALPATH" to completely
mirror the autotools path.
configure.in:
With current versions of FreeBSD, threading is not done on
the user-level any more, so the huge "net retry count"
is not needed any more.
This definitely holds for FreeBSD version 6 and up.
Adapt the informational messages to the path taken.
