5. Using XFree86 with Motif

The Motif libraries shipped with LynxOS x86 2.3.0 and 2.4.0 can be used with the XFree86 libraries. Follow the steps outlined below after you have installed XFree86 and LynxOS Motif on your system.

5.1. Copy Motif files

You must create symbolic links for the Motif libraries and utilities in the /usr/X11R6 directory tree.

      ln -s /usr/bin/X11/uil /usr/X11R6/bin
      ln -s /usr/lib/libUil.a /usr/X11R6/lib
      ln -s /usr/lib/libMrm.a /usr/X11R6/lib
      ln -s /usr/lib/libXm.a /usr/X11R6/lib
      ln -s /usr/lib/X11/uid /usr/X11R6/lib/X11
      ln -s /usr/include/Xm /usr/X11R6/include
      ln -s /usr/include/Mrm /usr/X11R6/include
      ln -s /usr/include/uil /usr/X11R6/include
  

The Motif imake-configuration files are part of the LynxOS X Window package. They must be copied to the /usr/X11R6 directory tree.

      cp /usr/lib/X11/config/Motif.* /usr/X11R6/lib/X11/config
  

5.2. Motif library patch for LynxOS x86 2.3.0

The XFree86 libraries are compiled with the -mposix compiler option while the Motif libraries shipped with LynxOS x86 2.3.0 are not. This incompatibility will cause Motif XmFileSelection widgets to be linked with the wrong (i.e. POSIX) directory routines. To circumvent this problem apply the following patch to the library:

      cp /usr/lib/libXm.a /usr/X11R6/lib
      ar x /usr/X11R6/lib/libXm.a Xmos.o
      ar x /lib/libc.a directory.s.o
      ld -r -o x.o Xmos.o directory.s.o
      mv x.o Xmos.o
      ar r /usr/X11R6/lib/libXm.a Xmos.o
  

This patch is not necessary for LynxOS revisions after 2.3.0.

5.3. X11R6 config file patch

Edit /usr/X11R6/lib/X11/config/lynx.cf and change the definition of HasMotif

from

       #define HasMotif    NO
  

to

       #define HasMotif    YES
  

5.4. Motif config file patch

The file Motif.tmpl shipped with LynxOS Motif must be modified to work with XFree86. In every reference to UnsharedLibReferences the first argument must be changed

from

       UnsharedLibReferences(<Something>LIB, Arg2, Arg3)
  

to

       UnsharedLibReferences(<Something>, Arg2, Arg3)
