SYSV IPC:function not implemented

SYSV IPC:function not implemented

Post by Damien Ne » Thu, 15 Apr 1993 12:01:04



I'm trying to get SYSV IPC working on my 0.99.8 kernel. The diffs installed
nicely for the most part, and I added the ones that didn't by hand. The kernel
compiled without complaint. However, whenever I run a program that uses IPC,
I get a `Function not implemented.' error. I'm at a loss. Does anyone have any
suggestions?

Many thanks!

For ipcdelta.tar.z

1) The patch in fsync.cd is needed only with linux-0.99.7.
   Back it out with patch -R if you applied it.

2) The diffs in ipc.cd fail in kernel/sys.c
   The patch is trying to delete the stub for sys_ipc()
   present in this file. So edit kernel/sys.c and remove
   the lines

   int sys_ipc (void)
   {
        return -ENOSYS;
   }

Mail me if you have problems.

HELP please HELP please HELP (I've fallen and I can't reach my beer!)

        Seriously..... I need some help with my Xconfig now that I've gotten
        an SVGA monitor.  (I've been doing great with a basic 640x480 setup...
        but....)

        I've a DELL 486 Performance series.... the VGA chipset on the board is
        a WDC31.  Running in normal vga mode 640x480 with the "pvga1" chipset
        has worked great with the following Xconfig entries, but I can't
        seem to get 1024x768 INTERLACED to work for me.

#######  current (working just dandy) settings
# clock  horzontal timing      vertical timing
 "640x480"   25     640  672  768  800    480  490  492  525
#######

                The new monitor is a "1024x768 i" monitor (from dell as well)
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                If anyone has any ideas, I could surely use them
(Mailing me a shrink wrapped Xconfig that works would certainly be a bonus)
:)  ( note: I'm running Xfree-86 1.2 -> it's grrrreat !)
                        Thanks !!

                        -Lance  

(If anyone is interested I'll mail ya anything that I get !)

The WD90Cxx chipset isn't yet supported for interlaced modes.  It should
work in the next release of X386.

Please follow the comp.windows.x.i386unix newsgroup for more information.

1. Implementing BSD functions in SysV

I was compiling a programme written for BSD on an RT running SysV and
got the following response:

                /bin/cc -a    prog1.o prog2.o -llib1 -llib2 -llib3
        ld: Undefined -
                .bzero
                _bzero
                .insque
                _insque
                .remque
                _remque
                .gethostname
                .inet_addr
                .gethostbyname
                .socket
                .connect
                _gethostname
                _inet_addr
                _gethostbyname
                _socket
                _connect
                _end
        *** Error code 1

        Stop.

It seems that SysV doesn't support these functions (bzero seems easy
enough to implement by hand, insque/remque somewhat harder, and the
socket/inet functions virtually impossible).  Can I replace these functions
with SysV functions and get the same functionality?  If so, how?

Please reply by e-mail.  Thanks in advance.
