Hello,
let me bring two tests from the configuration into focus.
These are plainly misconceived to properly examine BSD systems.
I do not understand how the C-code snippets used by "./configure"
are brought in, so I must refer to "./config.log" in explaining
the reasons of failure for OpenBSD or FreeBSD.
A general observation is that these two BSD versions do __not__
automatically include "<sys/types.h>", which GNU/Linux is very keen
in doing. This is the reason why both tests considered here are
misconceived, as they fail in the configuration stage for the
wrong reason.
If these problems should be regarded as bugs of the GNU Autotools,
then please help me by forwarding the following remarks to the
suitable authority!
1. OpenBSD and FreeBSD
From config.log:
configure:24416: checking wether getutent is declared
configure:24416: gcc --std=gnu99 -c -g -O2 conftest.c >&5
In file included from conftest.c:295:
/usr/include/utmp.h:54: error: syntax error before "int32_t"
/usr/include/utmp.h:63: error: syntax error before "int32_t"
The file "conftest.c" __must__ be written with the inclusion
#if HAVE_UTMP_H
# include <sys/types.h>
# include <utmp.h>
#endif
Presently <sys/types.h> is missing. Addition of this header file
will prevent the syntax error to go away, thus rendering the test
meaningful again. It will still fail though, since neither OpenBSD
nor FreeBSD knows of getutent(), pututent(), but that is another
story. However, the files "inetutils/src/utmp_*.c" will still fail
at compile time since the are not written with this latter deficiency
in mind.
2. FreeBSD
This one is very important since it prevents the building of
lib/libgnu.a properly.
From config.log:
configure:10925: checking whether forkpty is declared without a macro
configure:10952: gcc --std=gnu99 -c -g -O2 conftest.c >&5
In file included from conftest.c:135:
/usr/include/libutil.h:69: error: syntax error before "void"
/usr/include/libutil.h:83: error: syntax error before "size_t"
/usr/include/libutil.h:85: error: syntax error before "int64_t"
(further four similar statements)
The file "conftest.c" __must__ be written with the inclusion
#if HAVE_LIBUTIL_H
# include <sys/types.h>
# include <libutil.h>
#endif
The further tests
configure:18419: checking whether forkpty is declared
configure:10925: checking whether openpty is declared without a macro
configure:23478: checking whether openpty is declared
must be altered in an identical way.
According to the manual page pty(3) in FreeBSD, openpty(3) and
forkpty(3) are in fact expecting
#include <sys/types.h>
#include <sys/ioctl.h>
#include <termios.h>
#include <libutil.h>
but my quick tests indicate that <sys/types.h> and <libutil.h>
together with the linker flag "-lutil" would be sufficient
to conduct the tests used in the configuration step.
