Building on the Hurd

Building on the Hurd

[Evans Winner]

Does anybody here know anything about building Emacs on the GNU/Hurd/
Mach platform?  I am trying to get a Debian Hurd system up and
running, which, I am aware, is experimental.  apt-get won't let me
install any flavor of Emacs because of dependency problems, so I tried
building from cvs and the compile failed with an error.  I tried
building the 22.1 release tarball and got the same error.  I posted a
note about it to emacs-pretest-bug, for whatever that might be worth.

Are there, possibly, libraries I need that I don't have, or maybe
options I need to pass to configure?  Configure runs without any
problems, so I'm not sure how to proceed.  I will post the last few
lines of make output in case anyone recongnizes something.

What is FFDLY, anyway?

Thanks for any leads.

Plain old Debian GNU/Linux on x86:

/usr/include/asm/termbits.h:

struct termios {
        tcflag_t c_iflag;               /* input mode flags */
        tcflag_t c_oflag;               /* output mode flags */
        tcflag_t c_cflag;               /* control mode flags */
        tcflag_t c_lflag;               /* local mode flags */
        cc_t c_line;                    /* line discipline */
        cc_t c_cc[NCCS];                /* control characters */
};

struct termios2 {
        tcflag_t c_iflag;               /* input mode flags */
        tcflag_t c_oflag;               /* output mode flags */
        tcflag_t c_cflag;               /* control mode flags */
        tcflag_t c_lflag;               /* local mode flags */
        cc_t c_line;                    /* line discipline */
        cc_t c_cc[NCCS];                /* control characters */
        speed_t c_ispeed;               /* input speed */
        speed_t c_ospeed;               /* output speed */
};

//...

/* c_oflag bits */

#define FFDLY       0100000

Right.  Hmm.  Of course the problem is that on this system
grep -r FFDLY /usr/include/* results in nothing.  There is
in fact no asm/ subdirectory.  I wonder if there is some
package I can conveniently install that provides that.

In any case, I looked at the code and decided that there was
a good chance I could just delete the one symbol.
Compilation then proceeded past (yay!) to another error
(boo!) in (iirc) fileio.c line 6153 in which the symbol
`insdef' was undefined in a struct.  All my googling has
told me so far is that it seems to have once been a part of
the Emacs code, but it looks like it's no longer used,
except that compiling on this platform has caused the code
to reach this point that usually isn't reached.  At least,
that's my guess.  Does `insdef' have a standard meaning to C
coders?

I am beginning to think that it would be better to just
install Hurd from the ISOs (which means buying a replacement
for my broken IDE CD-ROM drive).

OSX, which is some dodgy bastardisation of BSD/mach I think:

geespaz:~ phil$ grep FFDLY /usr/include/*/*
/usr/include/sys/termios.h:#define      FFDLY           0x00004000      /* form feed delay */
 
SunOS:

bash$ grep FFDLY /usr/include/*/*
/usr/include/sys/termios.h:#define      FFDLY   0100000

Couldn't find it on plain FreeBSD though:

asdf ~ grep FFDLY /usr/include/*/*
asdf ~ grep FFDLY /usr/include/*  
asdf ~ find /usr/include -name termios.h
/usr/include/sys/termios.h
/usr/include/termios.h

You should be able to pick one up for a few quid at a car 
boot sale nowadays. I've got several spare myself.

You can loop-mount the ISO from the harddrive by using
mount ~phil/hurd.iso /mnt/cdrom -o loop,ro

However this won't work a boot time.
You might be able to use the ISO from your existing Hurd install
to attempt to repair the installation.

I think you will be much better off asking such questions on
emacs-devel@gnu.org, not here.
