1.  X11R6/XFree86[tm] on Interactive Unix

This document provides some additional information about compiling and using
X11R6 and XFree86 on your Interactive Unix, also referred to as ISC.

If you have any suggestions, comments, fixes or ideas regarding X11R6/XFree86
on Interactive Unix, send e-mail to

michael.rohleder@stadt-frankfurt.de

Bug Reports should be sent to

XFree86@XFree86.Org

Questions or anything else should be posted to the NewsGroup

comp.windows.x.i386unix

There is currently no support for shared Libraries so it will be filespace con-
suming if you want to build X11-clients with X11R6. Best you mix X11R6 Server
with X11R5 and X11R4 clients. And only compile clients who need the new facili-
ties provided in the X11R6 Libraries against them.


2.  Things needed for compiling the sources

      gcc
            Use the highest number for x you found.  Fresco will only build
            2.6.3 and later.  I'd tried gcc Version 2.5.8, 2.6.0, 2.6.2, 2.6.3
            and 2.7.2.  Current: 2.7.2.3

            Since 2.6.3 the current source tree should be able to compile with
            a little bit more Optimization:
             #define DefaultCDebugFlags -O3 -fomit-frame-pointer inside
            xf86site.def to overwrite the default -O2.

            With 2.7.x you must specify #define UsePosix               YES
            inside xf86site.def.  This is necessary to build the sources suc-
            cessfully.  Versions prior to 2.7.0 could define it, but don't need
            it for a clean build.

      libg++-2.x.x
            The needed g++ Libraries for use with g++ 2.x.x. As this is only
            necessary for Fresco, it isn't needed anymore since X11R6.1.

      binutils
            You could use the assembler and linker the assembler is most pre-
            ferred,and the linker is needed at least if you want to link
            libFresco.a within a Program.  Don't use strip and ar/ranlib, the
            first generates buggy binaries when stripping (at least on my
            machines) and the last requires the use of ranlib after creating an
            archive, this is not configured.  Current: 2.8.1.0.15 (Used: as,
            ld, ar, strip)

      gnu-malloc
            Due to better memory usage we should use GNU's malloc library on
            systems where possible.

            Enable #define UseGnuMalloc YES inside xf86site.def or within the
            Linkkit site.def.

            Enable and set #define GnuMallocLibrary to your needs, if it isn't
            like the default -L/usr/local/lib -lgmalloc.

      inline-math (optional)
            This is the "original" inline-math package available at your
            favorite Linux Mirror.

            Use #define UseInlineMath YES inside host.def to enable it. Please
            note the changes section what else to do, to use this package.



3.  Changes to the System Header Files

You have to change some of the standard header files supplied with your version
of Interactive. You also need to change some of the include files in the gcc-
lib/include directory.

Let us say the gcc-files are in directory

/usr/local/lib/gcc-lib/i[345]86-isc[34].[0-9]/2.6.x

referred to as "gcc-lib"

3.1  /usr/include/sys/limits.h

and gcc-lib/include/sys/limits.h

               #ifndef OPEN_MAX
               #ifdef ISC
               #define OPEN_MAX        256
               #else
               #define OPEN_MAX        20
               #endif
               #endif











 Information for ISC Users                                                    3



OPEN_MAX had to be increased to prevent Xlib Errors (max no. of clients
reached).

3.2  /usr/include/sys/ioctl.h

surrounded by

             #ifndef _IOCTL_H
             #define _IOCTL_H
             ...
             #endif



to prevent multiple includes.

3.3  /usr/include/errno.h

(and the corresponding gcc-include-file) add

             #include <net/errno.h>



because of EWOULDBLOCK undefined in several places regarding lbx.  Surround
/usr/include/net/errno.h with

             #ifndef _NET_ERRNO_H
             #define _NET_ERRNO_H
             ...
             #endif


to prevent multiple includes were <net/errno.h> is explicit included from the
sources.

3.4  /usr/include/rpc/types.h

copy this file to gcc-lib/include/rpc/types.h and change the declaration of
malloc() to

              #if !defined(__cplusplus)
              extern char *malloc();
              #endif


Note that this is only necessary if you want to build Fresco

3.5  /usr/include/sys/un.h

such a file does not exist on Interactive. You may like to generate it, if you
don't like a warning from depend. It isn't needed to compile the sources suc-
cessfully.









 Information for ISC Users                                                    4



You could use the following to produce it:

              #ifndef X_NO_SYS_UN
              struct  sockaddr_un {
                      short   sun_family;             /* AF_UNIX */
                      char    sun_path[108];          /* path name (gag) */
              };
              #endif


3.6  /usr/include/math.h

To use the Inline Math package you have to change your existing math.h. Please
note, the way I include the new Header file, is different than suggested in
inline-math's README.

Please add the following at the bottom of math.h, before the last #endif

     #if defined(UseInlineMath)

     /* Needed on ISC __CONCAT, PI */
     #ifndef __CONCAT
     /*
      * The __CONCAT macro is used to concatenate parts of symbol names, e.g.
      * with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
      * The __CONCAT macro is a bit tricky -- make sure you don't put spaces
      * in between its arguments.  __CONCAT can also concatenate double-quoted
      * strings produced by the __STRING macro, but this only works with ANSI C.
      */
     #if defined(__STDC__) || defined(__cplusplus)
     #define __CONCAT(x,y)   x ## y
     #define __STRING(x)     #x
     #else   /* !(__STDC__ || __cplusplus) */
     #define __CONCAT(x,y)   x/**/y
     #define __STRING(x)     "x"
     #endif  /* !(__STDC__ || __cplusplus) */
     #endif

     #ifndef PI
     #define PI M_PI
     #endif

     #include "/usr/local/include/i386/__math.h"
     #endif



4.  make World

     BOOTSTRAPCFLAGS="-DISC [-DISC30 | -DISC40] -DSYSV [-Di386]"

      -DISC -DISC30
            these two defines are necessary to build the release I don't know
            if the build will succeed for ISC versions prior than 3.x








 Information for ISC Users                                                    5



      -DISC40
            are only for getting the ISC version and therefore set the HasSym-
            Links to Yes ('cause symbolic linking were only supported from Ver-
            sion 4.x using the S5L Filesystem)

            If you could use long filenames, you could enable the installation
            of expanded Manual Pages by including
             #define ExpandManNames  YES inside xf86site.def.

            A build on ISC 4.x only needs -DISC40 defined in the BOOT-
            STRAPCFLAGS ( -DISC30 will be included automatically ).

            Note: due to some incompatibilities between ISC 4.0 and 4.1, the
            default is to build for ISC4.0, even if you build on 4.1.  If you
            want to build only for 4.1 you should set  #define IscCompileVer-
            sion       410  inside your host.def.

            (the fchmod function isn't available on 4.0, so it won't compile,
            and binaries from 4.1 won't run cause of the unsupported System
            call The libraries build for 4.1 couldn't be used with 4.0 Systems,
            due to some functions not available on 4.0)

      -DSYSV [-Di386]
            standard defines for SystemV Release3 on x86 platform.  You don't
            need to explicitly define -Di386 because this is pre-defined in
            /lib/cpp.


5.  linear Addressing

   o Compiling ...

     If you want to include support for linear addressing into the server bina-
     ries, you have to define

          #define HasSVR3mmapDrv        YES


     in xf86site.def.  This is necessary to get the correct setup to be defined
     for the build.

     You need the mmap-2.2.3 driver installed on your system.  If you don't
     have the mmap-2.2.3 driver installed, you could use the driver source in
     the file

          xc/programs/Xserver/hw/xfree86/etc/mmapSVR3.shar


     or

          /usr/X11R6/lib/X11/etc/mmapSVR3.shar


     Build and install the driver as instructed. You'll need the file








 Information for ISC Users                                                    6



     /usr/include/sys/mmap.h for compiling the X11R6/XFree86 source tree, with
     linear addressing enabled.

   o Using ...

     To use the linear address-mapping of the framebuffer you need the mmap
     Driver by Thomas Wolfram (Version 2.2.3) installed in your Kernel.  If you
     have installed it, most servers will use linear addressing by default.
     Others may require setting the

          Option "linear"


     in your XF86Config.   Check the appropriate manual pages for details.
     Maybe you need also the MemBase specified in XF86Config. Please refer to
     the appropriate README of your Card/Server, for How to use...  Note that
     the P9000 server will not work at all unless linear addressing is avail-
     able.

     I could only test these cards against the linear addressing.

        o Spea/V7 Vega - clgd5428 - VLB

          with 32MB MainMemory installed I couldn't use it.  My tests with dif-
          ferent mappings into the address space results in no Graphics dis-
          played or a spontaneous reboot.

        o ATI GUP      - mach32   - VLB

          with 32MB MainMemory installed I could map the CardMemory at MemBase
          0x07c00000. I could work with all clients until I try to activate a
          Motif 1.1.1 InputField inside a Motif Client like Mosaic-2.4 or
          xplan. This results in a crash of the XServer.

                          !!! You could work around this !!!



          Expand your .Xdefaults with

                          *blinkRate:             0
                          *cursorPositionVisible: false


          This bug seems to be fixed since 3.1.2, and therefore the workaround
          is not needed anymore.

        o ELSA Winner 2000PRO/X Revision G

          if you experience a Problem with this Card you could try to use the
          older Chipset Driver instead "newmmio".

          If you declare









 Information for ISC Users                                                    7



                          Chipset "mmio_928"



          inside your XF86Config, it may be alright again.

          With the current XF86_S3 I don't encounter any problem.


6.  XKeyboard Extension

   o Sample Setup ...

     Here is a sample XKeyboard Definition to include inside the Keyboard Sec-
     tion of your XF86Config File.

              Xkbkeycodes "xfree86"
          /*    XkbSymbols  "us(pc101)+de_nodead"  */
          /*    This has changed between 3.1.2E and 3.1.2F */
          /*    it is now:                                 */
              XkbSymbols  "us(pc102)+de(nodeadkeys)"
              XkbTypes    "default"
              XkbCompat   "default"
              XkbGeometry "pc"

     or you could use this one with the new Options:

             XkbRules        "xfree86"
             XkbModel        "pc102"
             XkbLayout       "de"
             XkbVariant      "nodeadkeys"


7.  Multibuffer Extension

This is an obsolete Extension. Anyway, if you want to include this Extension
inside your build, you have to add: #define BuildMultibuffer        YES inside
xf86site.def Please note, this Extension should be disabled when building the
Loader Server.


8.  Sample Definitions

This is my current host.def, if I build the sources. (So no more changes were
necessary in xf86site.def, either it isn't to bad to have a look inside it ;-)

9.  Installation

After your make World BOOTSTRAPCFLAGS="... succeed,

     make install









 Information for ISC Users                                                    9



to install in /usr/X11R6. Make sure you have enough space, and /usr/X11R6
exists either as a directory or a symlink to another directory maybe in another
filesystem.

     make install.man


to install the compressed nroff versions of the manual pages into
/usr/X11R6/man. This directory will be generated if it doesn't exist.

     make install.linkkit


to install the server binary LinkKit into /usr/X11R6/lib/Server.

            You could tune the Kernel using the command-file

            /usr/X11R6/lib/X11/etc/xf86install

            This will increase the available pseudo devices,
            some Tunable Parameters and install some files
            to use inside sysadm. You could also install
            some additional Fonts and Terminal files.

You also should increase MAXUMEM to its maximum, else programs may die with:

     X Error of failed request:  BadAlloc (insufficient resources for operation)
       Major opcode of failed request:  53 (X_CreatePixmap)
       Serial number of failed request:  37791
       Current serial number in output stream:  37822
       Widget hierarchy of resource: unknown


10.  Using ...

   o Xprt:

     The new Xprint Server is configured to use lpr as its print helper so you
     have to install and configure lpr to use Xprt.

   o Keyboard:

     You don't need any modmap-File to get your keyboard working with any
     iso-8859-1 Font. Simply enable

        o LeftAlt  Meta

        o RightAlt ModeShift

        o RightCtl Compose

     in your XF86Config - Section "Keyboard"










 Information for ISC Users                                                   10



   o xpcterm:

     if you want to get the German 'Umlaut' inside your ISC X11R4 client xpc-
     term when you are using the ega/vga font. Set up the user's .Xdefaults to
     contain:

                   XEga*AT386.Translations: #override \
                             Shift<Key>odiaeresis: string(0x99) \n\
                                  <Key>odiaeresis: string(0x94) \n\
                             Shift<Key>adiaeresis: string(0x8e) \n\
                                  <Key>adiaeresis: string(0x84) \n\
                             Shift<Key>udiaeresis: string(0x9a) \n\
                                  <Key>udiaeresis: string(0x81) \n\
                             Shift<Key>ssharp: string(0x3f) \n\
                              Meta<Key>ssharp: string(0x5c)  \n\
                                  <Key>ssharp: string(0xe1)


     The only disadvantage is that you have to use Alt instead of AltGr to get
     the \ Backslash (on a German Keyboard)

     You have to call your xpcterm with the option -name XEga -fn ega

   o Switching between X11R5 and X11R6 configuration

     to compile X11-Clients as either R6 or R5 clients, should be as easy as
     you only switch the PATH components so that either /usr/X11R6/bin/xmkmf or
     /usr/X386/bin/xmkmf would make the new Makefile.

   o ISC Streams Pipes

     The old path to the pipes on ISC's R4 /tmp/.X11-unix has changed to
     /dev/X/ISCCONN. For compatibility reasons on ISC, the pipes in the new
     directory will be linked to a file inside the old.  This will normally be
     a hard link, so it can't go across filesystems. On ISC Version 4.x this is
     now allowed. But you should use the new S5L on both filesystems.  ISC30
     systems should take care that the two directories are on the same FS. Else
     if you are using a ISC40 compiled binary, the Server could maybe abort due
     to a SIGSYS.  We tried to catch this signal, so if it dumps please send me
     a note.

   o Warnings you may see:

        o Since 3.2A, you could see a warning from pre X11R6.3 clients.

                          Warning: Unable to load any usable fontset



          The case are the new gzipped fonts, but the Warning isn't serious.
